Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a copy form for copying and filling in a lower sheet by filling in an upper sheet, and more particularly, to a copy form that can prevent falsification of entry items by being copied and written on the back side of the upper sheet as a copy.
[0002]
[Prior art]
In this conventional copy form, a dye-encapsulating microcapsule is provided on the back side of the upper sheet, while a developer layer is provided on the front side of the lower sheet, and a transferable developer is formed on the surface of the developer layer. A colorant layer is provided.
[0003]
[Problems to be solved by the invention]
According to this conventional example, copying on the surface of the lower sheet is performed by a reaction between the developer layer provided on the surface and the dye-encapsulating microcapsule layer provided on the back surface of the upper sheet. Since there is a transferable developer layer on the surface of the layer, there is a disadvantage that the copied image is unclear. It is an object of the present invention to provide a copy form that eliminates this inconvenience.
[0004]
[Means for Solving the Problems]
In order to achieve this object, the copy form according to claim 1 of the present application is formed by superposing a lower sheet on the lower side of an upper sheet provided with a dye-encapsulating microcapsule layer on the back side. the, provided with a self-color former layer comprising a dye containing microcapsules and a developer, the surface of the self-coloring agent layer, a developer, metastatic color appearance mainly fluidity oil, wax An agent layer is provided.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment in the case where the present invention is applied to a copy receipt will be described in detail with reference to the accompanying drawings. Here, FIG. 1 is a plan view, and FIG. 2 is a cross-sectional view taken along line AA of FIG.
[0006]
As shown in FIGS. 1 and 2, the copy receipt 1 is composed of an upper sheet 3 serving as a copy of one end side separably bound with a weak adhesive 2 having a weak adhesive force and a lower sheet 4 delivered to an issue destination. As shown in FIG. 1, the upper sheet 3 has a receipt date entry column 6, an issuer entry entry column 7, a receipt amount entry entry column 8, a receipt content entry entry column, under the title 5 “Receipt”. Each entry field 9 is provided and an issuer display 10 is printed in advance.
[0007]
As shown in FIG. 2, on the back side of the upper sheet 3, there are portions corresponding to the entry fields of the receipt date entry field 6, the issuer entry entry field 7, the receipt amount entry field 8, and the receipt content entry field 9. The dye-encapsulating microcapsule layer 11 is provided. As the microcapsules constituting the dye-encapsulating microcapsule layer 11, known ones can be used, but those made into ultraviolet curable inks that can be applied in a spot manner and can be dried quickly without heating are preferable. It is.
[0008]
On the other hand, although not shown, on the front side of the lower sheet 4, the same entry fields are provided at positions corresponding to the lower positions of the entry fields 6, 7, 8 and 9, respectively, as shown in FIG. In addition, a self-coloring agent layer 12 composed of a known dye-encapsulating microcapsule agent and a developer is provided on a portion of the upper sheet 3 facing the dye-encapsulating microcapsule layer 11, and the surface of the self-coloring agent layer 12 is provided. Is provided with a transferable developer layer 13.
[0009]
This transferable developer layer 13 is prepared as a non-aqueous transferable developer ink, and is mainly composed of a developer, fluid oil, and wax. It is prepared by adding a known auxiliary agent such as an agent, a photopolymerization initiator, a thickener, and a gelling agent.
[0010]
As the developer, for example, viscosity, phenol resin, polyvalent metal salt of aromatic carboxylic acid, or a mixture thereof can be used. In particular, zinc of 2,2-bisphenolsulfone compound is used because of good storage stability of printing. Salts and the like are preferred. The fluid oil is colorless and does not have an unsaturated double bond that inhibits the reaction between the color former and the developer, and has a low viscosity and good coating suitability. For example, lubricating oil not containing aromatics and normal paraffin are preferable. Further, as the wax, a relatively hard wax having a colorless melting point of 55 to 85 ° C. and a penetration of the wax of about 5 (25 ° C.) is used as the base wax, and the transferability and contamination are controlled. For the purpose, a soft wax is added to prepare a low hardness, and examples thereof include carnauba wax, wood wax, paraffin wax, and coconut wax.
[0011]
It should be noted that an ethylene-vinyl acetate copolymer is preferably added to the transfer developer ink, and this copolymer is highly compatible with wax and has an action of increasing the viscosity of the ink. This is because the adhesive property to the dye-encapsulating microcapsule layer 11 applied to the back side of the upper sheet 3 is enhanced.
[0012]
Next, a method of using the copy receipt 1 configured as described above will be described. When a predetermined item is entered in each entry column 6, 7, 8, 9 of the upper sheet 3 with an appropriate writing tool such as a ballpoint pen, the transfer pressure developer layer is formed on the back surface of the upper sheet 3 by applying writing pressure. Thirteen transferable developer inks transfer, react with the dye in the dye-encapsulated microcapsule layer 11 to develop a color, and the same content is copied. At the same time, the developer of the self-color-developing layer 12 reacts with the dye of the dye-encapsulating microcapsule layer 11 to develop color on the surface of the lower sheet 4 and the developer of the self-color-developing layer 12 As the color reacts with the dye, the same content as the written item is clearly copied.
[0013]
Here, the upper sheet 3 and the lower sheet 4 are separated, and the copied lower sheet 4 is handed over to the issue destination, while the upper sheet 3 is stored as a copy of the issuer. At this time, even if the person in charge of issuing the copy receipt 1 or the person in charge of accounting falsifies the contents of the upper sheet 3, since the regular contents of the upper sheet 3 are copied and entered, the upper sheet 3 3 is compared, it can be discriminated at a glance whether the description on the front side is regular or has been tampered with.
[0014]
The present invention is not limited to the above-described embodiment. For example, the dye-encapsulating microcapsule layer 11 provided in the upper sheet 3, the transferable developer layer 13 and the self-coloring agent layer provided in the lower sheet 4. 12 may be provided on the entire surface of each sheet 3, 4 as well as the corresponding part of each entry column 6, 7, 8, 9. Of course, the present invention can be applied to copy forms other than the copy receipt 1 that need to be prevented from being falsified. Furthermore, the upper sheet 3 and the lower sheet 4 may be line-bound with a strong adhesive having a strong adhesive force, and a cut perforation may be provided inside the line-bound portion.
[0015]
【The invention's effect】
As is apparent from the above description, according to the copy form described in claim 1 of the present invention, it is possible to clearly carry out copy entry on the lower sheet, and to copy the lower sheet on the lower surface of the upper sheet. Since the same regular entry contents as the entry contents are copied, it is possible to determine at a glance whether the description contents on the upper sheet front side are genuine by comparing the description contents on the front and back surfaces of the upper sheet. It is effective in preventing falsification.
