Description
Technical field
The present invention relates to no carbon paper processing technique field, more specifically, relate to a kind of anti-counterfeiting carbonless copy paper and preparation method.
Background technology
In prior art, there is anti-fraud functional no carbon paper and be widely used in the aspect such as bill, voucher.In order to ensure the normal operation of China's economy, hit the bill fraud criminal activity in this field, false proof and fake between trial of strength constantly upgrade, require that manufacturing enterprise constantly releases novel bill anti-counterfeit technology imperative.Along with the development of society and the progress of science and technology, the watermark used in the no carbon paper that bill (as tax bill) is used, color fibre, the single anti-counterfeiting technologies such as temperature change, light change can not meet the requirement that current bill management identifies, need to increase the anti-counterfeiting technology with high-tech, novelty, plyability.
In anti-counterfeiting carbonless copy paper field, the patent relating to anti-counterfeiting carbonless copy paper is more.As patent of invention ZL200410027088.2 relates to color fine anti-counterfeiting carbonless copy paper, patent of invention ZL200710027832 relates to fluorescent grain anti-counterfeiting carbonless copy paper, and also have other anti-counterfeiting carbonless copy papers related to both at home and abroad, comprise watermark, fluorescent fiber, temperature become coating false proof, day photochromic material and Chemical recognition is false proof etc., only in a second to several seconds, just can be differentiated by certain identification facility, and false proof change detects by an unaided eye very accurately obviously.But this kind of anti-counterfeiting technology all needs to be used for manifesting certain anti-counterfeiting characteristic by light, heat, chemical reagent, specific apparatus etc., too much depend on raw material and extraordinary instrument, such that such anti-counterfeiting carbonless copy paper cost is high once fraud molecule is easily copied after getting false proof raw material.
Therefore, marginal period enterprise to be produced constantly releases novel bill anti-counterfeit technology, its product exceeded and depends on additional specified conditions and Special Tool, utilization and easy method thereof just can popularly identify, also possess the false proof bill paper using that anti-counterfeiting information is variable, be easy to administrative department's monitoring.
Summary of the invention
The present invention is intended to solve the problems of the technologies described above at least to a certain extent.
The object of this invention is to provide a kind of have differentiate simple, the popular antifalse effect identified, overcome the anti-counterfeiting carbonless copy paper that existing anti-counterfeiting carbonless copy paper needs the defect by the additional specified conditions of this kind of dependence such as light, heat, chemical reagent, specific apparatus and Special Tool identification anti-counterfeiting characteristic.
A further object of the present invention is to provide a kind of preparation method of above-mentioned anti-counterfeiting carbonless copy paper, the anti-counterfeiting carbonless copy paper adopting this preparation method to prepare does not rely on additional specified conditions and Special Tool, only need carry out by the very common hard material such as nail, plastic cards in life the mode that small size scrapes back and forth or draw, there is the specific anti-false sign information such as the pattern of different colours, word, symbol or lines, thus reach the false proof object differentiating simple, popular identification.
The technical solution adopted for the present invention to solve the technical problems is: a kind of anti-counterfeiting carbonless copy paper, comprise body paper, carbonless copying paper and coating and the anti-counterfeit paint layer with invisible graph form expressing information, described carbonless copying paper and coating contains the microcapsules of different color development color, the coating of described anti-counterfeit paint layer comprises colour development material, adhesive and auxiliary agent, and described invisible graph is worked on body paper or carbonless copying paper and coating through coating method by given shape by the coating of anti-counterfeit paint layer.
In one embodiment, the number proportioning of described anti-counterfeit paint layer is: colour development material 30 ~ 80 parts, adhesive 5 ~ 15 parts, auxiliary agent 1 ~ 5 part.
In a preferred embodiment, described colour development material be atlapulgite, to aryl phenolic resin, zinc salicylate or modified phenolic resins.Wherein said atlapulgite is the clay that the activity based on silicate is stronger.Described zinc salicylate main component is 3,5-bis--2 toluoyl zinc salicylate.Phenolic resin and phenolic resins have different color developing effects by the product of function modified gained, the present invention by modification gained to aryl phenolic resin and modified phenolic resins to raising color development speed, strengthen coloring intensity and there is higher antifalse effect.
In a preferred embodiment, described auxiliary agent is polyoxyethylene nonylphenol ether sodium sulfosuccinic diester, this auxiliary agent plays a part lubrication, accelerates dispersion in described anti-counterfeit paint layer, improve the adaptability of coating processing, especially have good utilization benefit to administration measure and the false proof quality of raising.
In a preferred embodiment, the coating average grain diameter of described anti-counterfeit paint layer is less than 1.0 μm.The readability that the coating particle size direct relation invisible graph of anti-counterfeit paint layer manifests, particle diameter increases its anti-counterfeiting information picture and text definition and is deteriorated.The coating particles size controlling of the anti-counterfeit paint layer that the present invention uses is being less than 1.0 μm, differentiates there is certain benefit to the anti-counterfeiting information picture and text of product.
In a preferred embodiment, the average grain diameter of the microcapsules of described different color development color is less than 10 μm.The crocking resistance of the particle size direct relation no carbon paper of microcapsules, particle diameter increase can cause rub resistance value to raise, and rub resistance value is excessive, and anti-counterfeiting carbonless copy paper is processed and easy mass problem in transportation after manufacture.The grain diameter of microcapsules that the present invention uses controls be less than 10 μm, has significant benefit to the production aft-loaded airfoil of product and transport.
In one embodiment, described is to express anti-counterfeiting information with one or more compounds of pattern, word, symbol or lines with invisible graph form expressing information.
The present invention provides a kind of preparation method of above-mentioned anti-counterfeiting carbonless copy paper simultaneously, comprises the following steps successively: the coating of a, configuration anti-counterfeit paint layer; B, the coating of anti-counterfeit paint layer is worked on body paper or carbonless copying paper and coating by given shape through coating method; C, the carbonless copying paper and coating of the microcapsules containing different color development color by no carbon paper technique coating; D, oven dry, rewinding.
In one embodiment, described coating method is spraying, roll marks, printing or coating.
The anti-counterfeiting carbonless copy paper prepared by above-mentioned preparation method observes changeable anti-counterfeiting information by scraping or drawing, be included in the mode this anti-counterfeiting carbonless copy paper face using the hard material such as nail, plastic cards carry out small size to scrape back and forth or draw, occur the anti-false sign information such as the pattern of different colours, word, symbol or lines.
The invention has the beneficial effects as follows: the preparation method of anti-counterfeiting carbonless copy paper of the present invention is flexibly easy, is easy to production control, be applicable to various ways and produce.The no carbon paper of gained does not rely on additional specified conditions and Special Tool, only need carry out by the very common hard material such as nail, plastic cards in life the mode that small size scrapes back and forth or draw, the specific anti-false sign information such as the pattern of different colours, word, symbol or lines can be there is, thus reach the antifalse effect differentiating simple, popular identification.
