Abstract
The utility model relates to an anti-counterfeiting paper which can change in types under the situation of temperature inversion. The anti-counterfeiting paper comprises a paper base layer on which an anti-counterfeiting material layer is coated; aqueous solution of the anti-counterfeiting material which can change under the situation of temperature inversion is coated or spayed on the paper by special facilities and then the paper is dried to obtain the anti-counterfeiting paper which can change in types under the situation of temperature inversion. The paper of the utility model can be widely used in the industries such as printing, packaging, etc. Any part of the paper can respond to change in types under temperature inversion if being heated, and the color of the heated part changes from white to blue, and turns to white after heating is stopped. The color of the paper can even turn to yellow if the ingredients of the chemical solution are adjusted. The anti-counterfeiting paper of the utility model has proper cost and can coordinate with other anti-counterfeiting techniques to be widely used in anti-counterfeiting for industries such as printing of books and journals, food packaging, clothing, bills, various cards and certificates, etc.
Description
Technical field
The utility model relates to a kind of paper, but is specifically related to a kind of inversion modification counterfeit prevention paper.
Background technology
Because counterfeit and shoddy goods remain incessant after repeated prohibition, the anti-counterfeiting technology means still very need at present.False proof in industries such as book and periodical printing, packaging for foodstuff, clothes, bill and all kinds of card cards because cost is higher, improved the price of product itself, and the while antifalse effect also haves much room for improvement.
Summary of the invention
The purpose of this utility model, but be to provide a kind of effect inversion modification counterfeit prevention paper obvious, that differentiate easily.
The technical solution of the utility model is as follows.
But a kind of inversion modification cheque paper comprises paper substrate, is coated with the anti-fake material layer on described paper substrate, specifically is to be coated with the anti-fake material layer on the one or both sides of described paper substrate.
But the utility model inversion modification cheque paper, the cost cost is not high, has good false proof indicating effect, can cooperate separately or with other anti-counterfeiting technology, is used for the false proof of industries such as book and periodical printing, packaging for foodstuff, clothes, bill and all kinds of card cards.
Description of drawings
But accompanying drawing is the structural representation of the utility model inversion modification cheque paper.
Among the figure: 1, paper substrate, 2, the anti-fake material layer.
The specific embodiment
Referring to accompanying drawing, but inversion modification cheque paper, by paper substrate 1 with to meet the test solution that matches be that the anti-fake material layer 2 of variable color is formed.After with the industry special equipment anti-fake material liquid being sprayed on the paper oven dry again, form anti-fake material layer 2, promptly made anti-forge paper, be used for printing, packing.When the heating of any position of the possibility of reversal anti-forge paper of making, the effect of possibility of reversal all can appear.The heating position of paper becomes blueness by white, and this position returned to original white again after heating stopped.When this possibility of reversal warm type cheque paper runs into the colourless aqueous solution that is used to test, yellowing immediately.Be stained with test solution with cotton swab or writing brush, but inversion modification cheque paper is somebody's turn to do in contact or wiping, the contact site promptly becomes yellow or other color.
Claims (2)
1. but an inversion modification cheque paper comprises paper substrate (1), it is characterized in that: be coated with anti-fake material layer (2) on described paper substrate (1).
2. but inversion modification cheque paper according to claim 1 is characterized in that: be to be coated with anti-fake material layer (2) on the one or both sides of described paper substrate (1).
