Abstract

The invention discloses environment-friendly halftone printing ink which comprises the following formula components by weight percent: alcohol-soluble PU resin, keto-aldehyde resin, NC resin, pigments, talcum powder, polyethylene wax, an adhesion promoter, acetic ether, isopropanol and absolute ethyl alcohol. During use, the isopropanol and the absolute ethyl alcohol serve as diluents. The environment-friendly PU resin and the adhesion promoter are selected, the printing ink has a high adhesion force to OPP / PET / NL subjected to surface treatment; the NC resin is selected, so that the printing ink has high strength and solvent release property and has high reproducibility on layered printing halftone dot; by selecting the keto-aldehyde resin, the dispersion property and the color painting property of the pigment and filler are improved, the selected solvent is environment-friendly and non-toxic, is suitable for halftone exquisite printing requirements and is suitable for printing elegant packaging of medicines, food and other artware, and the requirements on market environment friendliness and high-grade exquisite printing can be met.

Description

technical field [0001] The invention relates to an environment-friendly halftone printing ink. Background technique [0002] Currently popular printing inks in the market use solvents that are not environmentally friendly, cause serious environmental pollution, and may cause solvent residues to contaminate packaging, and ink halftone layer printing effects are not good. . Contents of the invention [0003] The object of the present invention is to provide an environment-friendly half-tone printing ink, which has good strength and solvent release, and has the characteristics of good reproducibility of half-tone dots for layered plate printing. [0004] The present invention is achieved in that a kind of environment-friendly halftone printing ink is characterized in that: the weight percentage of its formula composition is: [0005] Alcohol-soluble PU resin 10%-50%, ketone-formaldehyde resin 3%-20%, [0006] NC resin 0-10%, pigment 5%-35%, [0007] Talc powder 0-10%, pol...
