Description

FIELD OF THE INVENTION

The present invention relates to an IC-mounted card substrate and an IC-mounted card substrate having an image-receiving layer, which are suitably applied in a contact-type or noncontact-type card or sheet, and which electronically store personal information requiring security with respect to prevention of forgery or alteration, an IC-mounted personal-data certification card utilizing the substrate.

BACKGROUND OF THE INVENTION

As a personal-data certification card such as an identification card (ID card) and a credit card, a magnetic card which records data by means of a conventional magnetic recording method has been commonly utilized. However, a magnetic card had problems of insufficient anti-tampering with data due to the ease of rewriting of the data, of insufficient protection of data due to environmental susceptibility of the magnetic record and of insufficient memory capacity. Therefore, an IC card including an IC-tip has become popular in recent years.

However, the quality of information recorded on a conventional pre-formed IC card did not meet the requirements. For example, the surface of an IC-mounted card substrate caused unevenness or ununiformity between an IC-mounted portion and the other portion, due to the differences in factors such as hardness, thermal conductivity, thermal shrinkage after heat press, and resulted in unsuitable as a recording surface. Specifically, an IC-mounted cards had problems of causing unevenness of the surface more easily compared to a card without an IC.

JP-A 7-88974 (JP-A refers to an unexamined and published Japanese Patent Application) discloses providing an image-receiving layer and a cushion layer on an IC card substrate, however, durability of the card was not sufficient because of possible penetration of chemicals or water at the card edges due to inadequate chemical resistance of the cushion layer.

Further, a method, in which a non-cushion actinic ray-cured resin is used in an image-receiving layer of an IC-card in order to reduce thermal shrinkage occurring during printing of information recording, is disclosed in JP-A 2000-298714, however, this method had a problem in that in practical use, curling of the card resulted due to photo-curing shrinkage when the resin was photo-cured. Further, a porous film was used to provide a cushioning property, however, the cushioning property was a problem which caused insufficient printing quality due to the use of a thermal transfer recording medium. The chemical resistance of a material used for a cushion layer also resulted in insufficient durability of the card.

In order to diminish unevenness caused on the card surface, IC-card preparation methods such as, 1) utilizing an electronic part having a predetermined thickness for use in the card and 2) specifying the thickness of an adhesive, were tried in JP-A 2000-211278, however, they were not enough to diminish the unevenness of the surface.

SUMMARY OF THE INVENTION

The object of the invention is to provide an IC-mounted card substrate, which prevents deformation of a card, improves printing properties by use of means such as a thermal transfer recording medium, and exhibits improved durability of the card due to more resistance to penetration chemicals and water through the card's edges and an IC-mounted personal-data certification card utilizing the card substrate.

DETAILED DESCRIPTION OF THE INVENTION

The invention will be detailed below.

In the invention, superior printability onto an image-receiving layer of a card substrate can be achieved without affecting unevenness of the surface by providing a cushion layer comprising an actinic ray-cured resin to solve the problem described above. Further, by the use of a actinic ray-cured resin cushion layer of the invention, a card can be free from damaging due to penetration of such as chemicals, and also damaging of an IC-tip caused by external stress can be prevented through stress relaxation by the cushion layer (strength against point pressure).

A cushion layer comprising an actinic ray-cured resin of the invention can be incorporated into an IC-mounted card substrate by a) being provided between an image-receiving layer and an electronic part fixing layer or by b) being combined with an image-receiving layer (an image-receiving layer is provided with cushioning property to be a cushioning image-receiving layer comprising an actinic ray-cured resin), and thereby printing property, chemical resistance, strength against point pressure and curl property of an IC-mounted card substrate have been enhanced.

In the case of an image-receiving layer being a non-cushioning actinic ray-cured resin layer, a card commonly had a tendency to suffer from curling with photo-curing shrinkage, however, the configuration of a) described above, in which a cushion layer comprising an actinic-ray cured layer is provided under an image-receiving layer, has been able to reduce curing shrinkage due to photo-cure to improve curl property thereby, and a combined-type of b) also has been able to reduce photo-curing shrinkage to minimize curl tendency.

An IC-mounted personal-data certification card prepared by providing a protective layer comprising such as a photo- or thermo-cured resin on the IC-mounted card substrate of the invention can provide a durable IC-mounted personal-data certification card with further enhanced printing property, chemical resistance and strength against point pressure.

The IC-mounted card substrate includes one with a printed format on the card substrate. The embodiment may be of any form, such as a roll, sheet or card form. The format printing is a printing of a format composed of such as ruled lines and boxes for recording information of identification and literatures, concretely, such as a company name, an address, a name, a birth date, a name of a card, a notice and a telephone number of a publisher, etc., and may include plural formats for printing these information.

An IC-mounted personal-data certification card means an IC card provided with an image element on an IC-mounted card substrate and bearing at least one selected from an identifying image such as a face image, an attribute information image and a format printing.

As a print board, a thermoplastic film such as polyester is used, and polyimide is advantageously used in the case of relatively high thermal-resistance being required. The bonding of an antenna pattern with an IC-tip is performed by any method commonly known such as a method utilizing electroconductive adhesives such as silver paste, copper paste, carbon paste, etc, (for example, EN-4000 series produced by Hitachi-Chemical Ind. Co., Ltd. and XAP series produced by Toshiba Chemicals Co.); a method utilizing anisotropic conductive film (Anisolm produced by Hitachi Chemical Ind.

<Method for Equipping an Electronic Part Between the First Sheet Member and Second Sheet Member>

As a manufacturing method of equipping the foregoing electronic part between first and second sheet members, any of a thermal paste-up method, an adhesives paste-up method and an extrusion-molding method, which are commonly known, can be utilized. Further, formation of an identification image such as a face image, format printing or information recording may be performed before or after the first sheet member and the second sheet member are laminated together, and they can be formed by any method such as offset printing, gravure printing, silk printing, screen printing, intaglio printing, letterpress printing, an ink-jet method, a sublimation transfer method, an electrophotographic method and a thermal fusion method.

At the time of lamination, to enhance smoothness of the substrate surface and adhesion of the electronic parts predetermined between the first sheet member and the second sheet member, they are preferably subjected to heating and pressing, and preferably manufactured by such as an up-and-downward press method and a lamination method. Further, planer-press type is preferred so as to provide nearly line contact and avoid using rolls which may provide unreasonable bending force by even a slight shift, taking cracking of IC-parts into consideration. The heating is preferably performed at 10 to 180° C., and more preferably 30 to 150° C. The press is preferably performed at 9.81×10 to 2.94×10 4 kPa, and more preferably at 9.81×10 to 1.96×10 4 kPa. When the pressure is higher than this, IC-tip may be collapsed. The time for heating and pressing is preferably 0.001 to 90 sec., and more preferably 0.001 to 60 sec. When the time is longer than this, the production efficiency is lowered.

Further, when using a moisture-curable adhesive whose reaction speed is decreased by the effect of such as moisture, that means adhesion force or durability of the card being deteriorated, it is more effective to perform the lamination process in vacuo or in a nitrogen atmosphere. In the lamination process, because the first sheet member for a substrate, the electronic parts holding material and the second sheet member for the front surface are laminated with each other together under predetermined pressing and heating conditions, by utilizing the electronic parts holding material itself as an adhesive, the substrate material, the electronic parts holding material and the surface substrate can be laminated in good reproducibility.

The thus laminated sheet prepared as a continuous sheet by adhesive-laminating method or resin extrusion method described above, may be recorded with identification images and bibliographic items after allowed to stand for a predetermined time, and, thereafter, is shaped into a predetermined card size.
