Problems solved by technology

Jiangsu Taige Ink Co., Ltd. produces light-changing inks for cigarette packaging materials, mainly used on packaging sheets and skins, such as small boxes of hard cigarette boxes, carton packaging of cigarettes, and soft packaging of cigarettes At present, the small boxes used are all ester-soluble optical variable inks, and their VOCs are mainly ethyl acetate, n-propyl acetate and dilution solvent n-propyl acetate in the ink. The content in the ink is 50-70%, and the dilution ratio According to the original ink: diluent = 2:1, therefore, the release of n-propyl acetate and ethyl

Abstract

The invention discloses an alcohol-soluble nitrocotton optically variable ink. The alcohol-soluble nitrocotton optically variable ink is characterized in that: ethanol is adopted as a main solvent, and other components include: 16.0-20.0% of alcohol-soluble nitrocotton, 4.0-8.0% of alcohol-soluble rosin, 0.0-5.0% of acetyl tributyl citrate, 8.5-9.5% of an optically variable pigment, 45.0-62.0% ofethanol, 8.0-12.0% of ethyl acetate, 2.0-5.0% of dipropylene glycol methyl ether, and 0-0.5% of alcohol-soluble color ink. Resin dissolution, optically variable pigment dispersion, color matching andinspection process methods are adopted to prepare the alcohol-soluble optically variable ink, the invention aims to prepare the optically variable ink that can save energy, reduce emission, lower thecost, meets the requirements of the existing market, and at the same time meets the requirements of environmental protection condition for VOC emission indexes, and the alcohol-soluble nitrocotton optically variable ink has higher economic benefits and social benefits.

Description

technical field [0001] The invention relates to the field of design inks, in particular to an alcohol-soluble nitrocellulose optically variable ink and a preparation process thereof. Background technique [0002] Optically variable ink is based on the interference principle of light. Natural light at different incident angles in different directions will produce coincident light with different interference wavelengths when reflected by the ink layer on its surface, so that the observer will have different visual perceptions of different colors at different angles. This effect cannot be achieved. It is copied by copiers, so it is used as an anti-counterfeiting material on banknotes, securities, tickets and high-end tobacco and alcohol packaging, and optically variable inks have very high requirements for production technology and equipment, so the cost is higher than other ordinary inks. Jiangsu Taige Ink Co., Ltd. produces light-changing inks for cigarette packaging material...
