Abstract

This invention relates to an anti-false fiber noncarbon paper and its production method aiming at overcoming the shortcoming of not anti-false of the current bills made of carbon copy paper which is made by adding a certain quantites of anti-false fiber original paper to produce primary anti-false then to be specially coated to produce the noncarbon paper with anti-false function.

Description

technical field [0001] The invention belongs to the technical field of papermaking, in particular to an anti-counterfeit fiber carbonless copy paper and a production method thereof. Background technique [0002] At present, carbonless copy paper is widely used in commercial forms such as banking, taxation, telecommunications, post and telecommunications, insurance, etc. for its advantages of easy use, clean hands, large number of copies, clear handwriting; convenient processing, neat overprinting; especially suitable for computer printing. Invoices, forms and documents for food, beverages, etc. [0003] With the expansion of the use of carbonless paper, some bill applications require carbonless copy paper to have anti-counterfeiting functions. At present, the anti-counterfeiting technology application of domestic carbon-free paper products mainly uses watermark anti-counterfeiting carbon-free paper produced by watermark base paper. Watermarking is to use equipment with cor...
