A means for forming an ultraviolet curing control layer having the second pattern is further provided.

According to the first, third, and fifth aspects of the present invention, the step of applying and curing the ultraviolet-curable resin coating solution by providing the ultraviolet-curable control layer provides The curing speed of the ultraviolet-curable resin coating film in the region can be controlled. If the curing speeds are different, a uniform film cannot be formed, so that the resin layer in that region has a slightly different refractive index than the resin layers in other regions. For this reason, the pattern shape of the substance for controlling the curability cannot be visually recognized in a normal emmetropic state, but can be visually recognized from a certain inclination angle. Compared with those having marks for authenticity judgment at first glance, the present invention has a good forgery prevention effect in that the existence of the authenticity judgment pattern is not easily understood.
can get. Even if the presence is known, it is extremely difficult to reproduce and forge a pattern having such a delicate visibility at a similar visibility level. If the pattern / information differs for each individual, the forgery prevention effect is even higher.

In the inventions according to the first, third, and fifth aspects, an ultraviolet-curable resin preferably used is an acid-curable alicyclic epoxy resin.

Materials used for the ultraviolet curing control layer include materials that promote curing, such as maleic anhydride,
Inorganic acids such as maleic acid, phthalic acid, phthalic anhydride, acetic acid, formic acid, and acrylic acid, or materials that inhibit curing, such as amines, sodium hydroxide, and potassium hydroxide, may be used. Due to problems such as properties, other basic acids such as sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, sodium bicarbonate,
Sodium phosphate, potassium phosphate, sodium hydrogen phosphate,
And potassium hydrogen phosphate are easy to use.

When these materials are selected, consideration must be given to corrosion in the apparatus.

These ultraviolet curing control layers can be applied by, for example, a sponge stamp method, an ink jet method, or a dropping method in which a coating solution containing these materials is contained in a sponge and applied in a desired pattern shape.

The pattern of the colored layer can be formed by thermal transfer of a sublimable dye-containing ribbon, thermal transfer of a pigment-dispersed hot-melt ribbon, pigment-dispersed ink jet, or electrophotographic recording.

As the ultraviolet shielding layer, a heat transfer type film containing an ultraviolet absorbent can be used.

In the method for manufacturing a personal authentication medium according to a second aspect of the present invention, instead of forming an ultraviolet curing control layer having a second pattern on an image receiving layer, a second pattern is provided on the image receiving layer. Except for forming the wettability control layer, the method is the same as the method according to the first aspect.

Further, the personal authentication medium according to the fourth aspect of the present invention comprises a second pattern formed on the image receiving layer instead of the ultraviolet curing control layer having the second pattern formed on the image receiving layer. Except for providing a wettability control layer having a pattern,
It has the same configuration as the personal authentication medium according to the third aspect.

Further, in the method of manufacturing a personal authentication medium according to a sixth aspect of the present invention, the method for forming an ultraviolet curing control layer having the second pattern on the image receiving layer is replaced with a method for forming the second ultraviolet curing control layer on the image receiving layer. Except for providing a means for forming a wettability control layer having the above pattern, the device has the same configuration as the device according to the fifth aspect.

According to the inventions according to the second, fourth, and sixth aspects, by forming a wettability control layer having a second pattern on an image receiving layer, an ultraviolet curable resin coating solution is applied. In the curing step, by controlling the wettability of a desired portion by the wettability control layer, it is possible to change the thickness of the ultraviolet-curable resin layer in the region. When the film thickness is different, the wettability control layer pattern shape cannot be visually recognized in a normal normal viewing state, but can be confirmed by its unevenness or a change in refractive index due to a difference in film thickness. According to these inventions, the anti-counterfeiting effect can be obtained in that the existence of the authenticity determination pattern is not easily recognized as compared with the one having the authenticity determination mark at first glance. Even if the presence is known, it is extremely difficult to reproduce and forge a pattern having such a delicate visibility at a similar visibility level. If the pattern / information differs for each individual, the forgery prevention effect is even higher.

The material of the wettability controlling layer used in the invention according to the second, fourth and sixth aspects includes carnauba wax, paraffin wax, microcrystalline wax, polyethylene wax, stearyl alcohol, silicone oil, silicone Waxes, silicone resins, fluorine-based oils, fluorine-based waxes, fluorine-based resins, higher fatty acid salts such as zinc stearate, and the like can be used.
