INK COMPOSITION FOR BLOCKING UV RAYS, AND METHOD FOR PRODUCING SUBSTRATE HAVING EMBOSSED SURFACE USING SAME

WIPO Patent Application WO/2024/095560

A1

The problems addressed are: to provide an ink composition for inkjet printing for blocking UV rays that is capable of forming a printed layer capable of suitably blocking UV rays; and to provide a method for producing a substrate having a desired embossed surface using said ink composition. Provided as a solution is an ink composition for inkjet printing for blocking UV rays, wherein the ink composition contains 55.0 mass% or more of a photopolymerizable monomer, from 3.0 mass% to less than 15.0 mass% of a UV absorber, and from 10.0 mass% to less than 30.0 mass% of a non-polymerizable material, and the content ratio of polyfunctional monomer in the photopolymerizable monomer is 50.0 mass% or more relative to the photopolymerizable monomer.
