Abstract

The invention belongs to the carbonless copy paper processing technology field, in particular to a temperature-changing anti-counterfeiting carbonless CB/CFB paper as well as the production method thereof. The temperature-changing anti-counterfeiting carbonless CB/CFB paper has the technical proposal that temperature-changing materials are added into the common CB coating, and when being heated to reach a certain temperature, the paper is changed from white to other colors. The temperature-changing anti-counterfeiting carbonless CB/CFB paper has the following anti-counterfeiting means that the temperature-changing materials in a certain proportion are added in the common CB coating under room temperature, the appearance of the temperature-changing anti-counterfeiting carbonless CB/CFB paper is identical with the common carbonless paper, but when being heated to reach a certain temperature, the paper is changed from white to other colors, thereby realizing the anti-counterfeiting purpose.

Description

technical field [0001] The invention belongs to the technical field of carbonless copy paper processing, in particular to a temperature-changing anti-counterfeiting carbonless CB / CFB paper and a production method thereof. Background technique [0002] Carbonless copy paper has been widely used in tickets, vouchers, securities, labels, etc. Due to its special purpose, users and management departments often require appropriate anti-counterfeiting functions to be added to the paper to prevent criminals from forgery. [0003] Anti-counterfeiting carbonless paper products currently on the market usually add anti-counterfeiting means to the carbonless paper base paper, and then coat and process to produce carbonless copy paper with anti-counterfeiting functions, such as watermark carbonless anti-counterfeiting fiber carbonless paper, etc. Watermarking is the use of equipment with corresponding patterns and texts (such as watermark rollers, watermark nets, semi-wet embossing roller...
