Abstract

The invention discloses printing ink for anti-counterfeiting embossed tipping paper. The printing ink is prepared from the following raw materials in parts by weight: 50 to 60 parts of acrylic resin,14 to 18 parts of polyvinyl alcohol, 7 to 10 parts of an ethylene-vinyl acetate copolymer, 5 to 20 parts of pigment, 1.5 to 2 parts of silicon dioxide, 0.8 to 2.4 parts of a dispersing agent, 0.5 to 0.8 part of a leveling agent, 1 to 1.4 parts of an antifoaming agent and 25 to 40 parts of a solvent. The printing ink for the anti-counterfeiting embossed tipping paper is prepared from finely selected raw materials; the contents of the raw materials are optimized, so product quality is improved; and the prepared printing ink for the anti-counterfeiting embossed tipping paper has the advantages ofhigh adhesive force with the surface of the tipping paper, good toughness, small possibility of fading, breaking, cracking and the like in the later embossing treatment process of the tipping paper,applicability to the anti-counterfeiting embossed tipping paper, good stability and good migration resistance.

Description

Technical field

[0001] The invention relates to the technical field of ink for tipping paper, in particular to an ink for anti-counterfeiting embossed tipping paper and a preparation method thereof. Background technique

[0002] In recent years, tipping paper has developed rapidly in China, with great development and innovation in functions and uses. The use of tipping paper by tobacco factories is not limited to packaging, but pays more attention to its decoration, and has higher requirements for the printing aesthetics of tipping paper. Tipping paper has developed from a single single-color product to a multi-color product, and the proportion of multi-color products has increased year by year.

[0003] In the prior art, the production of tipping paper with various colors is usually made by adding pigments or dyes to printing inks and printing them through a printing press. Due to the chemicals used in the printing process of tipping paper, such as inks, pigments, organic solven...
