Problems solved by technology

[0003] Aiming at the disadvantages of the carbonless copy paper made by the existing technology, since the chromogen mainly adopts china clay and has a single component, the bills made of the copy paper have poor light resistance, easy oxidation, fading, and short storage time during use. The present invention provides A method for processing carbonless copy paper, the carbonless copy paper produced by the method has good light resistance, is not easy to fade, and has a long storage time

Abstract

The present invention is production process of no-carbon copy paper with high light tolerance, color fastness and long retention time. The production process includes the following steps: preparing cassava-corn glue, preparing developer paint, preparing color base paint, spreading the developer paint to the lower side of paper, and spreading the color base paint to the upper side of paper.

Description

(1) Technical field [0001] The invention relates to a processing method for various multi-part forms, multi-part receipts and invoice paper, in particular to a processing method for carbonless copy paper. (2) Background technology [0002] Carbonless copy paper does not need to be inserted into the "tabulation paper" when copying, and it does not need to be pulled out after writing. One-time copying can directly obtain copying materials, as long as the paper is stacked in the order of upper paper, middle paper, and lower paper, and written or typed with a pen When partial pressure is given, the capsules under pressure will burst, and the chromophores on the reverse side of the upper paper will transfer to the chromophores on the front side of the lower paper for chemical reaction, thus obtaining a clear imprint. Because there is no ink on its surface, it will not stain the paper surface and hands when using it. Checks and trust securities printed on this carbon paper are eas...
