Description

[Detailed description of the invention] (Industrial application field) The present invention is inspired by an authentication identification card that views a photographic image layer.

Especially regarding the "IE1 Abetsu card" which has a flat shape and moderate hardness.

(Prior art) As social institutions become more complex and the population increases, as a means of easily, quickly and accurately distinguishing the rights, qualifications, etc. specified for each individual to maintain the normalcy of social institutions and smooth the rotation of the institutions. Increasingly, authentication identification cards, such as driver's licenses, passports, credit cards, deposit carts, or employee credit cards, are being issued for each person.

Furthermore, the use of cards as optical or magnetic card keys in automatic discrimination systems incorporating computers has become widespread, as well as for artificial discrimination of the contents written on the cards.

Therefore, counterfeit creation of written contents as software is increasingly strictly prohibited, and at the same time, as hardware, requirements regarding standards such as shape retention and structural accuracy of the card are increasing.

Generally used edict cards are used in various ways, depending on their purpose of use and how they are carried around at all times. Served.

Many proposals regarding these measures have already been made, including Japanese Patent Publications No. 53-46080, No. 55-44703,

An example of this can be seen in the description of the number, etc.

An example is white opaque resin with certification information printed on it.

A credit card with a transparent resin sheet thermally bonded to both sides of the sheet, and a magnetic tape adhered to the surface of the sheet, or a paper sheet on which names, etc. are written, is pasted, or - optically or mechanically attached to the card Driving licenses, employee licenses, etc. with facial images engraved on them, or developed photo image sheets wrapped in two transparent resin sheets and laminated to prevent quantity.
Alternatively, a part of the sheet carrying authentication information etc. is punched out, a supporting piece such as a face photograph is aligned and filled in the punched out part, and a Seimei resin sheet is pasted on the entire surface of the carrying sheet, or a resin coating is used. The image-bearing side of the photographic paper using the base paper is peeled off at the paper layer of the base paper, the paper remaining on the back side of the image is ground into a thin layer, and the image-bearing thin layer is attached to the support sheet to further form the image. Identification cards are known in which a Seimei cover is adhered to the surface, or other opaque resin films are adhered to the photographic image surface of a Seimei photographic film.

However, in the case of conventional cards, the area for accommodating information is too small for the bulky size of the card, and the structure and

It is constructed by selecting and using resin sheets that have substantially the same thermal behavior.

The card of the present invention has a configuration in which the photographic image layer 1IiI11 is sandwiched between two resin sheets, a transparent resin sheet and an opaque side fat sheet, from both the front and back sides, and the photographic image layer t>iJ is disposed on the front and back sides. The photographic layer may be firmly coated in advance on either one of the resin sheets, or the photographic layer may be sandwiched as a sheet carrying the photographic layer coated on a separate support. Preferably 2 from the number of man-hours required to create the card.
It is in the form of a resin sheet σ) coated in advance.

When storing the 11v information in the photographic layer, a photographic method suitable for the photographic layer is applied. The photographic layer includes a black and white photo layer, preferably a color 1F+3 photosensitive layer, and an image receiving layer of each persimmon diffusion transfer PF type photosensitive material. −j, true law, diazo′q
The thermal behavior of the resin sheet sandwiching the 0'lJ page layer, which is a photosensitive layer etc. Equivalent materials are selected and used through experimentation. Preferably, materials with substantially equivalent thermal expansion rates are selected.

In general, the thermal expansion and contraction caused by heating a resin sheet varies depending on the resin material! 6. The f# resin sheet production method varies greatly depending on the molding temperature, stretching force, stretching direction, or degree of thermal relaxation.
Resin sheet material? At the critical temperature that is uniquely determined by the J film condition, the film may show a sudden fluctuation in elongation or contraction, or it may exhibit linear fluctuations without including the critical point, and the final maximum elongation and contraction directions of the fluctuation are respectively Varies depending on resin sheet type. It is also affected by the physical shape of the resin sheet (e.g. presence or absence of embossment, etc.), the porcelain of the filler, etc.
It should be said that the thermal behavior of resin sheets varies widely depending on the sheet type.

Therefore, the resin sheet related to the present invention is preferably a resin sheet that is formed from the same material, under the same film-forming conditions, has been acclimatized by thermal relaxation treatment, and has substantially the same thermal behavior.

In addition, in the present invention, the above-mentioned Seimei resin sheet, a photographic image sheet carrying a photographic image layer obtained from the photographic layer, and the Seimyo If!
