Description

[Detailed description of the invention] The present invention relates to printed materials such as bankbooks, slips, documents, etc., which have a stamping area to prevent forgery.

BACKGROUND ART Conventionally, identity verification when using bankbooks, slips, documents, etc. has been performed by comparing the impression of a seal affixed in a seal space with the impression of a seal owned by the person.

However, with this method, if a third party obtains a printed matter that already has a seal imprinted on the stamp column,
It is easy to falsify the seal impression to take advantage of this. Furthermore, with the method recently used especially for financial institution passbooks, in which a mask label is attached to the stamp area after stamping, it is relatively easy to peel off this label and falsify the stamped impression.

This proposal was devised in consideration of the above points, and the purpose is to produce printed matter that can easily identify the presence or absence of tampering, even if a seal is already affixed. Therefore, we adopted the following configuration.

That is, a release layer, a pattern printing layer, and an absorbing layer are sequentially laminated on a stamp area or a writing area on a base material, and the release layer is formed of a material with excellent surface smoothness, and the absorbing layer has a high degree of whiteness. It is made of a material that has high opacity and good hiding properties, and also has good absorbency such as ink.

According to this proposal, even if an attempt is made to form a new printing layer or absorbent layer after peeling off the absorbent layer for the purpose of tampering, the selection of an absorbent layer material that has the same white-hiding ability and maintains absorbency. , It is necessary to have considerable knowledge and equipment regarding the selection of printed layers and pattern printing materials with equivalent visual density, and positioning when forming a new printed layer in the case where only part of the printed layer 4 is peeled off. Because of this, it is difficult to falsify, and it is characterized by the fact that it is possible to obtain printed matter that is extremely suitable as a counterfeit prevention printed matter.

The embodiments shown in the drawings will be described below.

1 is the base material for bankbooks, slips, documents, etc.
A release layer 3 is provided on the stamp field 2 on the base material 1 so as to cover part or all of the stamp field.

As this peeling layer 3, a colorless transparent or colored transparent substance with excellent surface smoothness is used. For example, when forming a release layer using a printing method, as an ink body
Hot melt is used as UV silk ink, general silk ink, and wax type. Other methods include stamping with transparent foil, lamination with adhesive film, and the like.

A printed layer 4 with a suitable pattern is further formed on the peeling layer 3 formed as described above. The size of this layer is appropriately determined so as to cover part or all of the release layer.

Printing methods include screen printing, letterpress printing,
Although offset printing can be selected as appropriate, it is preferable that the adhesiveness with the release layer 3 is weak and the film-forming property is weak.

Next, an absorbent layer 5 is provided on the printed layer 4 formed as described above so as to cover the entirety of either the release layer 3 or the printed layer 4, whichever is larger.

The absorbent layer 5 is made of ink, a material that is highly absorbent to ink and has a high concealing property in order to imprint a seal or a signature on the absorbent layer 5.

For example, when the absorbing layer is formed by a printing method, the ink body is a silk screen printing ink containing pigments, absorbents, and additives as main components. As the absorbent, for example, substances such as silica, calcium carbonate, and zinc white are used.

In addition to the ink body, foil stamping may be performed using a foil made of a pigment, an absorbent, and an additive.

Now, the printed matter stamping section 2 created as above
A colorless transparent cover film or a colored transparent cover film 7 on which a release layer 3, a printing layer 4, and an absorption layer 5 are provided, a seal 6 is stamped, and an adhesive treatment 8 is applied on the back side of an OPP film or the like. cover with

In this state, it is issued as a printed matter with the stamp, but if a third party obtains this and peels off the cover film 7 in an attempt to falsify the seal impression 6, the seal impression 6, absorption layer 5, and printing layer 4 will be removed due to the release layer 3. It peels off while remaining adhered to the cover film 7 side.

Therefore, even if an attempt is made to form a new printing layer or absorption layer for the purpose of tampering, it is necessary to select an absorption layer material that has the same white hiding property and retains its absorption properties, a printing layer with the same visual density, and pattern printing. It is difficult to select the material and align the position when forming a new printing layer.
