Description
The application is 200910176476.X for application number, and the applying date is on September 16th, 2009, and denomination of invention is divided an application for the application for a patent for invention of " a kind of altering prevention paper and preparation method thereof ".
Technical field
The present invention relates to a kind of altering prevention paper and preparation method thereof, this altering prevention paper can be widely used in the anti-correction of security, certificate, bill, classified document etc. and false proof.
Background technology
Along with the progress and the expanding economy of science and technology, many marketable securities, certificate, classified document have been subjected to being altered the threat of forging, and many lawless persons utilize and alter the forgery means, carry out fraud, have upset normal financial order and civil order.A series of anti-correction technology is arisen at the historic moment, and compound film technology is a purpose stop to alter to forge, and the safety ink protection is printed on the information on the paper, but these still can not tackle the problem at its root, and has only the use altering prevention paper, just can reach the purpose for the treatment of both principal and secondary aspect of disease.So altering prevention paper arises at the historic moment.
The approach that information is endowed on the paper mainly contains: press printing; Printer prints; Scan and copy; Give by means of stationery etc. by people's hand.The reproduction of information realizes on paper by printing ink and ink.Printing ink and ink all form by colouring agent (dyestuff, pigment etc.) is dissolved or is dispersed in the solvent that is dissolved with binder, stabilizing agent and other auxiliary agents.Classify with regard to used solvent, have water-based, oily ink (printing ink) to distinguish.Used dyestuff has ACID DYES, basic-dyeable fibre, direct dyes etc.Correction fluid be exactly by with printing ink, ink generation physical-chemical reaction, its color is thin out, even a class material that disappears.At present, the commodity of existing correction fluid are many on the market, how with eradicator, opaquing fluid etc. as trade name.Though trade name is not quite similar, but on its chemical composition, mainly comprise following a few class material: organic solvent, mainly comprise ethanol, acetone, ethyl acetate, benzene, turpentine wet goods organic solvent, be mainly used in correction to oily ink (printing ink) information of giving; Acid, alkali mainly are hydrochloric acid, oxalic acid, NaOH etc., and the auxiliary constituent of correction fluid is with organic solvent, oxidant, reductant acting in conjunction; Oxidant, reductant mainly are hydrogen peroxide, hypochlorite (sodium), potassium permanganate, sodium hydrogensulfite etc., are used for the correction of information that water-base ink (printing ink) etc. is given.
Altering prevention paper is started to walk early abroad, and development is fast, and the altering prevention paper that appears at France the earliest is by dosing aldehydes matter in paper, still, because aldehydes matter has oxidisability, making that this paper life-span is very short.Afterwards, states such as Japan, Britain, Germany had taked to add aromatic series organic matters such as the complex compound, acid-base indicator, tannic acid, phenols of some metal etc., existed false proof narrow range, and were only effective to a certain class correction fluid; The paper life-span is short; In atmospheric environment, shortcoming such as easy to change.The progress and the expanding economy of science and technology, an urgent demand improves the quality of altering prevention paper.
Therefore, develop a kind of false proof wide ranges, the paper life-span is long, and is not easy to change, and the altering prevention paper of good stability just becomes the technical barrier that those skilled in the art's urgent need will solve.
