Abstract

The invention discloses an antifogging application of a radiation curing composition containing a pigment dispersion body. The radiation curing composition includes the pigment dispersion body (A), acationically polymerizable compound (B), and a cationic photoinitiator (C), does not use volatile solvents, is environmentally friendly, has excellent applicability to printing on a plastic film, andcan be quickly cured to show excellent production efficiency; a cured layer formed after the radiation curing composition is cured has excellent antifogging performance on the basis of ensuring excellent chemical resistance, scratch resistance, adhesion fastness with various base materials and traceability in a shrinkage process.

Description

technical field [0001] The invention relates to the fields of radiation curing and anti-fog, in particular to the application of a radiation-curable composition containing pigment dispersion in anti-fog. Background technique [0002] Plastic labels are usually attached to the surface of liquid containers in the existing market for indication or decoration purposes, among which shrink labels or stretch labels with good decoration and processability are widely used. The manufacture of these labels generally involves coating or printing the composition on the surface of a plastic substrate in order to impart decorative properties through the printed pattern. At this stage, research on printing compositions mainly focuses on new environmentally friendly formulations. Under the premise of meeting environmental protection, considerations for performance improvement focus on cost, production efficiency, adhesion, weather resistance, and chemical resistance of printed products. sex...
