DETAILED DESCRIPTION OF THE INVENTION

Lenticular Lens

The lenticular lens used in the present invention refers to an array of lenses (a lens array) comprising a plurality of arranged semicylindrical or arcuate and elongated convexes. The lenticular lens has a convex part surface, on which a plurality of semicylindrical or arcuate and elongated convexes are arranged in parallel, and a backside surface which is a surface of the lenticular lens remote from the convexes. The backside surface is substantially flat. FIG. 1 is a typical diagram showing a principle of the formation of a three-dimensional image or a motion picture by a lenticular lens. Specifically, a lenticular lens 1 has a surface, on which an array of a plurality of semicylindrical or arcuate and elongated convexes 2 arranged in parallel, and a backside surface 3 remote from the convexes 2. The backside surface 3 is substantially flat. An image 4 for the right eye and an image 5 for the left eye are provided preferably in contact with each other on the backside surface 3. When these images are viewed from the convex side, the image 4 for the right eye is perceived by the right eye 6 while the image 5 for the left eye is perceived by the left eye 7. When the image 4 for the right eye and the image 5 for the left eye are constructed so as to form parallactic images by the parallax between the two eye views by a viewer, the viewer perceives the images as a three-dimensional image. On the other hand, when two or more types of images, which are perceived differently depending upon the angle of line of sight, are provided for the image for the right eye and the image for the left eye, angle-dependent different images are perceived. In this case, when these images are brought to continuous images, they are perceived as a motion picture.

The recording medium according to the present invention comprises a layer of this lenticular lens. The lenticular lens layer may be formed of any material without particular limitation so far as the function of the lenticular lens is provided. Preferred materials include resins, for example, PET, PETG, APET, PP, PS, PVC, acrylic resins, and UV curing resins.

Recording Medium According to First Aspect of Invention

A recording medium 10 according to the first aspect of the present invention has a fundamental structure as shown in FIG. 2. In FIG. 2, an ink absorptive layer 8 is provided on a lenticular lens layer 1 in its backside surface 3, and an ink permeable layer 9 is provided on the outermost surface of the recording medium 10 remote from the lenticular lens layer 1.

In the recording medium according to the first aspect of the present invention, recording is carried out by an ink jet recording method from the ink permeable layer 9 side which is opposite to the lenticular lens layer 1. Ink droplets ejected by the ink jet recording method are deposited onto the ink permeable layer 9, are permeated through the ink permeable layer 9, reach the ink absorptive layer 8, and are fixed within the ink absorptive layer 8, preferably the ink absorptive layer 8 in its part very close to the backside surface 3 of the lenticular lens 1 to form an image. The image is formed by an ink jet recording method so as to be perceived as a three-dimensional image or a motion picture through the lenticular lens. The ink permeable layer 9 has the function of leading ink droplets to the ink absorptive layer 8 substantially without the fixation of the ink to the ink permeable layer, preferably the function of leading the ink droplets very rapidly to the ink absorptive layer 8. As a result, even immediately after image recording by an ink jet recording method, any ink does not stay on the recorded face of the recording medium 10, that is, on the surface of the ink permeable layer 9, and the image can be touched by a hand.

The ink absorptive layer 8 may have any composition without particular limitation so far as the ink can be fixed, preferably the ink can be fixed to a part very close to the backside surface 3 of the lenticular lens 1. Preferred materials for the ink absorptive layer 8 include water absorptive resins such as acrylic or methacrylic resins, vinyl chloride resins, vinyl acetate resins, nylons, styrene/acrylic resins, styrene/butadiene resins, polystyrene/acrylic resins, polystyrene/isoprene resins, methyl methacrylate/butyl methacrylate resins, melamine resins, polycarbonate resins, urea resins, epoxy resins, urethane resins, phenol resins, diallyl phthalate resins, and polyester resins, particularly preferably cationic water absorptive polymers, for example, polymers of neutralized salts and quaternized products of dialkylaminoalkyl (meth)acrylates such as dimethylaminoethyl (meth)acrylate and diethylaminoethyl (meth)acrylate, and dialkylaminoalkyl (meth)acrylamides such as dimethylaminomethyl (meth)acrylamide and dimethylaminopropyl (meth)acrylamide, and anionic water absorptive polymers, for example, polymers of (meth)acrylic acid, 2-acrylamide-2-methylpropanesulfonic acid, vinylsulfonic acid, styrenesulfonic acid, itaconic acid, maleic acid, fumaric acid, and arylsulfonic acid.

The ink absorptive layer 8 may comprise water absorptive or particle adsorptive inorganic particles. Examples of inorganic particles include silica, kaolinite, talc, precipitated calcium carbonate, heavy calcium carbonate, zeolite, alumina, barium sulfate, carbon black, zinc oxide, zinc sulfate, zinc carbonate, titanium dioxide, satin white, aluminum silicate, diatomaceous earth, calcium silicate, aluminum hydroxide, hydrated halloysite, magnesium carbonate, and magnesium hydroxide. These inorganic particles are preferably used in combination with a resin as a binder to form an ink absorption layer. Examples of such binders include polyester resins, polyurethane resins, polyester urethane resins, acrylic resins, melamine resins, polyvinyl alcohol resins, polyvinylpyrrolidones, and methylcelluloses. The inorganic particles may be mixed with the above water absorptive resin to form an ink absorptive layer 8.

The ink permeable layer 9 may be formed of any material so far as the material has the function of leading ink droplets to the ink absorptive layer 8. Preferably, the ink permeable layer 9 has a non-water-absorptive porous structure. This porous structure may be formed of particles. Examples of such particles include particles of silica, kaolinite, talc, calcium carbonate, zeolite, alumina, barium sulfate, carbon black, zinc oxide, titanium oxide, organic white pigment, benzoguanamine, crosslinked polystyrene, crosslinked acrylic polymers, and aluminum hydroxide. These particles may be fixed by a binder to form a porous structure. Examples of binders usable herein include polyester resins, polyacrylic resins, polyurethane resins, and various copolymers. Preferred binders include acrylic resins and acryl-styrene copolymers that have no significant water absorption.

In a preferred embodiment of the present invention, surfactants and the like may be added to the ink permeable layer 9 from the viewpoint of improving and regulating the ink permeation rate and the like.

In a preferred embodiment of the present invention, a recording medium having a white background can be provided by rendering any one or both of the ink permeable layer 9 and the ink absorptive layer 8 nontransparent.

Further, in one embodiment of the present invention, a layer may be provided between the ink absorptive layer 8 and the ink permeable layer 9. For example, a layer for enhancing the adhesion between both the layers may be provided.

The recording medium according to the first aspect of the present invention may be produced by dissolving or dispersing the component(s) for constituting the ink absorptive layer 8 and optionally the binder, for example, in water or an organic solvent to prepare a composition, coating the composition onto the backside surface 3 of the lenticular lens, drying the coating, coating a composition, prepared by dissolving or dispersing the component(s) for constituting the ink permeable layer 9 and the binder in a suitable solvent, for example, water or an organic solvent, onto the ink absorptive layer 8, and drying the coating.

A recording medium 20 according to the second aspect of the present invention has a fundamental structure as shown in FIG. 3. In FIG. 3, an ink absorptive layer 21 is provided on a lenticular lens layer 1 on its backside surface 3. More preferably, an ink permeable layer 22 is provided on the ink absorptive layer 21, that is, the surface of the recording medium 20 remote from the lenticular lens layer 1. Further, an adhesive layer 23 which surrounds the peripheral part of the recording medium is provided on the ink permeable layer 22, and also a release sheet 24 is provided on the adhesive layer 23. As will be described later, in the recording medium 20 according to the second aspect of the present invention, ink jet recording is carried out, the release sheet 24 is then separated, and, in this state, the recording medium 20 can easily be fixed through the adhesive layer 23 onto a support such as a wall, a cardboard, or a postcard.

In the present invention, the provision of the adhesive layer 23 on a part of the recording medium in its printing side suffices for the fixation of the recording medium onto a substrate. When reliable fixation is necessary, as shown in FIG. 3, the provision of the adhesive layer surrounding the peripheral part of the recording medium is preferred. Further, in FIG. 3, the adhesive layer 23 is provided on the ink permeable layer 22. Alternatively, as shown in FIG. 4, a construction may also be adopted in which the adhesive layer 23 is provided directly on the lenticular lens 1 in its adhesive layer forming region and the release sheet 24 is provided on the adhesive layer 23. In this embodiment, printing by an ink jet recording method is not substantially carried out in the part where the adhesive layer 23 has been provided. This part may be previously colored and subjected to printing of a pattern. In the recording medium according to the second aspect of the present invention, as shown in FIG. 5, a plurality of recording media are connected to each other by easy separation means 25. Examples of such easy separation means 25 include perforation and incisions to such a level that can easily cause breaking for separation of the plurality of recording media from each other.

The composition of the adhesive layer 23 is not particularly limited so far as the composition has tackiness high enough to fix the recording medium to a support. Further, the material for the release sheet 24 is also not limited so far as the sheet is adhered to the adhesive layer 23, has strength high enough to avoid the separation of the adhesive layer during carrying of the recording medium through an ink jet recording printer, and can easily be separated in the fixation of the recording medium to a support. For example, coated paper is preferred.

As with the recording medium according to the first aspect of the present invention, in the recording medium according to the second aspect of the present invention, recording is carried out by an ink jet recording method from the ink permeable layer 22 side which is opposite to the lenticular lens layer 1.

The image is formed by an ink jet recording method so as to be perceived as a three-dimensional image or a motion picture through the lenticular lens. The ink permeable layer 22 has the function of leading ink droplets to the ink absorptive layer 21 substantially without the fixation of the ink to the ink permeable layer, preferably the function of leading the ink droplets very rapidly to the ink absorptive layer 21. As a result, even immediately after image recording by an ink jet recording method, any ink does not stay on the recorded face of the recording medium 20, that is, on the surface of the ink permeable layer 22, and the image can be touched by a finger.
