Abstract

The invention discloses UV curable offset printing scale ink for gold and silver cardboards. The UV curable offset printing scale ink comprises the following ingredients (by weight): 33-37% of aldehyde ketone modified acrylate UV resin, 18-22% of bis-functional polyester acrylate UV resin, 7-12% of trimethylolpropane triacrylate, 1.5-2.5% of a cracked photoinitiator, 2.5-3.5% of a hydrogen abstracting type photoinitiator, 6.5-7.5% of an amine photoinitiator, 18-21% of wax and 3.3-4.7% of an auxiliary agent. The prepared one-component UV curable offset printing scale ink is solvent-free when in use, releases no toxic gas, is environment friendly and pollution-free, has characteristics of clear figure after curing, even coloring, good adhesion, fast curing speed and good fluidity, and can meet requirements of decorative ink.

Description

technical field [0001] The invention relates to the technical field of ink, in particular, the invention relates to UV offset printing scale ink on gold and silver cardboard materials. Background technique [0002] Gold and silver cardboard offset inks on the market are mainly solvent-based, and their ingredients contain a large amount of organic solvents, such as ketones, benzenes, esters, alcohols, etc., and organic solvents will volatilize in large quantities during construction Discharged into the air will pollute the environment, which is not conducive to environmental protection, and is not conducive to the health of operators. [0003] Therefore, it is necessary to seek a solvent-free UV offset scale ink for use on gold and silver cardboard. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art and provide a solvent-free environmentally friendly UV offset printing scale ink. After curing, the UV offset p...
