Description

FIELD OF THE INVENTION

The present invention relates to an image recording material and a transfer foil which are suitably applied to a contact- or non-contact type electronic or magnetic card, sheet, and the like, which store personal information and the like for which security is demanded to prevent forgery, altetration and the like.

BACKGROUND OF THE INVENTION

In recent years, contact- or non-contact-type electronic or magnetic cards, and the like, have increasingly been issued in the field of service industry such as banks, business organizations, educational institutions, public agencies, and the like. Personal information such as a portrait, a name, and the like, is recorded on image recording bodies such as cash cards, employee cards, company membership cards, membership cards, student cards, aliens registration cards, various types of license cards, and the like, which are employed in various fields. Accordingly, these cards are subjected to security treatment so that forgery as well as altetration is not readily carried out.

For example, a hologram layer is provided onto a card substrate and a special image is formed so that a portrait, a name, issue date, and the like are not readily imitated. Said image is generally called a diffraction grating image or a hologram image. Said hologram image is formed employing interference infringes obtained by overlapping waves which are reflected from a body or transmitted through a body with the reference waves. By employing said hologram image, the image of the body is stereoscopically reproduced. The surface of the hologram layer is covered with a protective sheet having high light transmission. Employed as said protective sheet are transparent resins and the like which are employed for lamination, and the hologram layer, which exhibits less strength than the card substrate, is covered with the protective sheet and thereby protected.

SUMMARY OF THE INVENTION

However, according to the method for producing cards using the conventional system, for instance, a laminate film and a hologram sheet are separately formed, and after passing through a laminating process, the extra laminate film is trimmed. Specifically for photo-bearing company membership cards, driver's license cards, and the like, in order to ensure positive identification with a flawless image, it is necessary that during the production process, the formation of scratches as well as wrinkling on the surface of the card is minimized, and further, that while cutting the film into a card shape, the generation of fins in the projected area which sticks out to the edges is prevented.

The present invention has overcome the aforementioned problems. An object of the present invention is to provide a transfer foil and an image recording material which enhance security by discouraging forgery, alteration, and the like, and which exhibit improved scratch resistance, are capable of minimizing the formation of scratches as well as winkling, and are capable of decreasing the formation of fins, and a method for preparing said image recording material.

The embodiments of the image recording material, the transfer foil, the transfer foil roll, the preparation method of the image recording material, and the production method for the transfer foil of the present invention will now be described below with reference to the drawings. However, the present invention is not limited to these embodiments, description and drawings. First, FIGS. 1 and 2 show an image recording material preparation apparatus of the first embodiment. FIG. 1 is a schematic structural view of the image recording material preparation apparatus, while FIG. 2 is a view showing the layer structure of an image recording material.

The transfer foil of the present invention comprises a support having thereon a releasing layer and at least one component layer. Further, said releasing layer comprises inorganic or organic fine particles. Still further, the general formulas described below are held:

Further, in order to protect an image recorded on an image recording material, the transfer foil of the present invention is preferably employed for the purpose of transferring a protective layer onto an image recorded on said image recording material. The releasing layer as described herein is the layer which is provided so that a component layer is readily peeled off from the support of the transfer foil. Incidentally, when said component layer is peeled from the support of the transfer foil, the entire releasing layer may remain on the support (namely, the releasing layer is not transferred onto the image recording material). Alternatively, one part of the releasing layer may be transferred onto the support, while the other part of the same remains on said component layer.

Further, said component layer possesses various functions and may be comprised of a single layer or a plurality of layers. Incidentally, preferable examples of said component layer include a transparent protective layer which protects images on the image recording material, a transparent hardening layer which is previously hardened by the irradiation of actinic light to protect images on the image recording material, an adhesive layer which is employed for adhering the transfer foil onto the image recording material, an optical variable device layer which varies optical performance, a barrier layer, a cushion layer, an interlayer, and the like.

Still further, said heat cross linking group and/or said light cross linking group includes at least a vinyl group, a methacryloyl group, an acryloyl group, a glycidyl group, an isocyanate group, and carboxyl group. When said fine particles having a heat cross linking group and/or a light cross linking group are employed, it is preferable that the component layer comprises a hardening layer which is adjacent to the releasing layer, because the effects of the present inventing are pronounced. It is more preferable that when the component layers are peeled from the support of the transfer foil, all component layers are peeled off (namely, the releasing layer is transferred onto the image recording material).

Also listed are those in which the part of the functional group or the entire functional group corresponding to each is modified to alkali metal salts, alkali earth metal salts, transition metal salts, and the like. Of these, preferred are alkali or alkali earth metal salts of polyacrylic acid, polymethacrylic acid, and polystyrene sulfonic acid, and specifically, sodium salts of polystyrene sulfonic acid are preferred from the viewpoint of compatibility with other resins, antistatic properties, and solubility, and viscosity of their solution.

Further, listed as electrically conductive particles are various metals, oxides such as ZnO, TiO 2 , SnO 2 , Al 2 O 3 , In 2 O 3 , MgO, CoO, CuO, Cu 2 O, SrO, BaO, BaO 2 , PbO, PbO 2 , MnO 3 , SiO 2 , ZrO 2 , Ag 2 O, Y 2 O 3 , BiO 3 , La 2 O 3 , Ti 2 O 3 , Sd 2 O 3 , Sb 3 O 5 , K 2 Ti 6 O 13 , NaCaP 2 O 18 , MgB 2 O 5 , and the like, sulfides such as CuS, ZnS, and the like, carbides such as SiC, TiC, ZrC, VC, NbC, WoC, and the like, nitrides such as Si 3 N 4 , TiN, ZrN, VN, NbN, TaN, Cr 2 N, and the like, borides such as TiB 2 , ZrB 2 , NbB 2 , TaB 2 , CrB, MoB, WB, LaB 6 , and the like, silicides such as TiSi 2 , ZrSi 2 , NSi 2 , TaSi 2 , CrSi 2 , MoSi 2 , WSi 2 , and the like, metal salts such as BaCO 3 , CaCO 3 , SrCO 3 , BaSO 4 , CaSO 4 , and the like, composites such as Si 3 N 4 -SiC, 9Ai 2 O 3 -2B 2 O 3 , and the like, materials doped with those, and the like.

In the present invention, electrically conductive particles are preferably mixtures consisting of at least two types of particles having different particle shapes. Entire electrically conductive particles are preferably comprised of some of particles having an average particle diameter of 0.01 to 0.5 μm and the remaining particles having an average particle diameter of 0.5 to 3 μm, and the preferred ratio is such that the former is 50 to 95 percent by weight and the latter is 5 to 50 percent by weight. When an antistatic layer is formed employing only particles having an average particle diameter of 0.01 to 0.5 μm, the resulting layer is effective for minimizing static charge as well as transparent spots. However, the following problems occasionally occur: a plurality of sheets are fed, stable running is not carried out, and adhesion to the sticky surface of an image layer immediately after preparing an image recording material is not minimized. Further, when said antistatic layer is formed employing only particles having a particle diameter of 0.5 to 3 μm, the following effects were obtained: static charge was minimized, the supply of a plurality of sheets was minimized, stable running was carried out, and adhesion to the sticky surface of an image layer immediately after preparing an image recording material was minimized.

Cationic polymerizable compound comprised of cationic polymerizable composition includes (1)styrene derivative, (2) vinylnaphthalene derivative, (3) vinylether and (4) N-vinyl compound.

Radically polymerizable series is preferable in the invention.

The hardenable layer contains unit represented by formula (1). The vinyl polymer having carboxylic acid of the formula (referred as vinyl polymer of the invention) is described.

The vinyl high molecular polymer employed in the invention preferably contains a unit represented by the above mentioned formula (1) at 0.001 to 5 wt %, more preferably 0.001 to 3 wt %. In case that the content of unit represented by the above mentioned formula (1) is not more than 0.001 wt %, the hardenable layer easily deteriorates in stability against chemicals and scratch strength due to reduction of polymerization degree, and in case that it is more than 5 wt %, in particular, more than 10 wt % there is such practical drawback as low yield because it causes gellation during synthesis.

In case that content of carboxyl group is more than 200 in terms of acid value, stability against chemical and strength against scratches deteriorate.

Though density of crosslinking in hardenable layer is improved, it is problematic because adhesive property to neighboring layer deteriorates in case that composition containing resin having unsaturated double bond is added to UV hardenable layer.

An actinic light hardening type resinous layer is provided in such a manner that transparent protective transfer foil 64 in FIG. 11 , optical variable device transfer foil 43 in FIG. 12 , hardening type transfer foil 66 in FIG. 13 , and hardening type resinous layer containing optical variable device transfer foil 44 in FIG. 14 are employed individually or in combination.

After providing the actinic light hardening resinous layer is provided as described above, exposure is carried out employing actinic light to form a hardened layer, and cards are prepared.

The transfer foil of the present invention comprises a support having thereon a layer which contains inorganic or organic fine particles comprising a heat and/or light cross linking group. In addition, said transfer foil comprises a support preferably having thereon a layer which contains inorganic or organic fine particles with an average particle diameter of 0.01 to 10 μm, comprising a heat and/or light cross linking group.

Said heat and/or light cross linking group has at least a vinyl group, an acryloyl group or a methacryloyl group, a glycidyl group, an isocyanate group, and a carboxyl group, and inorganic or organic fine particles comprising a heat and/or light cross linking group are incorporated into at least a releasing layer and a heat and/or light hardening layer.

Further, the transfer foil of the present invention comprises a transparent protective layer and/or an optical variable device layer transfer layer. Still further, said transfer foil comprises at least one releasing layer and the general formula described below is held.

(General Formula 1)

 Average particle diameter of inorganic or organic fine particles in the releasing layer/thickness of the releasing layer×100=1.0 to 400

Optionally employed as fillers of the transfer foil employed in the present invention may be fine organic or inorganic particles which are known in the art, as long as they are not excessively deformed during transfer formation of images.

Specific compounds include, as inorganic compounds, metal oxides such as silica, titanium oxide, aluminum oxide, zinc oxide, magnesium oxide, zirconium oxide, and aluminum borate; metal carbonates such as calcium carbonate, magnesium carbonate, and the like; metal sulfates such as barium sulfate, magnesium sulfate, and the like; metal hydroxides such as aluminum hydroxide, magnesium hydroxide, and the like; metal borides such as titanium boride, zirconium boride, and the like; metal carbides such as titanium carbide, zirconium carbide, niobium carbide, tungsten carbide, and the like; metal nitrides such as titanium nitride, zirconium nitride, tantalum nitride, and the like; metal silicides such as titanium silicide, zirconium silicide, molybdenum silicide,.and the like; others such as kaolin, clay, talc, diatomaceous earth, perlite, bentonite, mica, synthetic mica, and the like.

Listed as organic compounds are particles of melamine resins, guanamine resins, styrene-acryl resins, silicone resins, fluorine resins, polymethyl methacrylate, high molecular weight polyethylene, and the like.

Preferably, the aforementioned heat or light cross linking group containing inorganic or organic fine particles are substantially colorless. Their shape is optional and may be amorphous or crystalline such as spherical, acicular, tabular, or prismatic. However, from the aspect of the uniformity of a filler added layer, the spherical shape is specifically preferred. The preferred particle diameter of fillers varies depending on the thickness of the particle added layer. However, the average particle diameter is commonly in the range of 0.01 to 10 μm (when particles are amorphous, the longest available length of particles is employed), and is preferably between 0.01 and 2 μm. Those, which are specifically preferred in the present invention, are fine filler particles having an average particle diameter of 0.5 μm or less.

The average particle diameter, as described in the present invention, means not always the primary particle diameter of fine particles, and means the average particle diameter of fine particles which are incorporated into the releasing layer. The fine particles in the releasing layer may aggregate to from secondary particles or may be dispersed so as to be incorporated as primary particles. A measurement method is exemplified as follows: the releasing layer is peeled from the transfer foil and the surface of the releasing layer is observed employing an electron microscope. The length in the-long axis direction in the observed state is designated as the particle diameter and the average diameter in an area of 10 mm 2 of the observed releasing layer surface is calculated. Said measurement is carried out at randomly selected 10 positions in the same transfer foil. The average particle diameter of each 10-position is obtained and further the average of the resultant averages is obtained. Thus the average particle diameter of the fine particles of the transfer foil is preferably obtained.

Regarding the relationship between the average particle diameter of fillers and the thickness of the layer, the particle diameter of fillers is specifically preferred to be less than the thickness of the layer comprising particles. Methods to incorporate fillers-into the layer include one in which said fillers may be directly dispersed into the other components, or another one in which fillers which have been dispersed in a suitable dispersion medium may be added. In the present invention, a transfer foil comprising inorganic or organic fine particles in the releasing layer is expressed, and the resultant relationship is preferably in average particle diameter/thickness of the releasing layer×100=1.0 to 400. When the ratio is greater than 400, problems occur in which, when transfer is carried out, particles remain on the surface of the transferred base material, and the overall appearance is degraded. When the ratio is less than 1.0, problems also occur in which, when transfer and peeling are carried out, during peeling the transfer foil from the base material, the extraneous transfer parts remain on the base material surface (hereinafter referred to as fin).

In the present invention, the transfer foil comprises a releasing layer containing inorganic or organic fine particles. It has been discovered that, when the relationship of average particle diameter/thickness of the releasing layer×100=1.0 to 400 is held, the number of fins decreases.

It is preferable that when the inorganic or organic fine particles having a heat or light cross linking group, which are employed in the present invention, are on the surface of the releasing layer, said particles combine with the adjacent layer through actinic light to enhance the layer strength, and also improve adhesion. It is also preferable that when said particles resin in the hardening layer, said hardening layer combines with the adjacent layer through actinic light to enhance the layer strength and improve adhesion.

Of these, preferred are a vinyl group, an acryloyl group or methacryloyl group, and a glycidyl group. It is possible to synthesize these employing specific methods described in Japanese Patent Publication Open to Public Inspection Nos. 07-109355, 08-100006, and 09-204043. Specifically, it is possible to obtain inorganic fillers having a light cross linking group of the present invention, employing reactions of metal hydroxides such as silica having a hydroxide group on the surface of inorganic fillers, aluminum hydroxide, magnesium hydroxide, and the like with silane coupling agents having an unsaturated group such as an acryloyl group, a methacryloyl group, an acrylamide group, maleic acid diester group, an allyl group, a vinyl thioether group, a vinyl amino group, glycidyl group, and the like.

Further, it is preferable that when the fine inorganic or organic fine particle s having a heat cross linking group, which are employed in the present invention, are on the surface of the releasing layer, said particles combine with the adjacent layer through heat to enhance the layer strength and improve adhesion. It is also preferable that when said particles resin remain in the hardening layer, said hardening layer combines with the adjacent layer through heat to enhance the layer strength and improve adhesion.
