Document Type and Number:
WIPO Patent Application WO/2024/029176
Kind Code:
A1
Abstract:
The present invention addresses the problem of obtaining a photocurable inkjet ink composition that can be brought to a viscosity suitable for inkjet ink compositions, that realizes a satisfactorily high reactivity, and that can reduce the migrating substances that are produced from the coating film of the cured photocurable inkjet ink composition. As a solution to the problem, a photocurable inkjet ink composition is provided that contains the following A to E, has a viscosity of not more than 100 cps, and has a surface tension of not more than 32.0 mN/m: A. an ethylenically unsaturated bond-containing polymeric photopolymerization initiator, B. a thioxanthone-type compound that has a photosensitizing action, C. a (meth)acrylate-type polymerizable compound, D. a (meth)acrylamide-type compound and/or an aminobenzoate compound, and E. a surface conditioner.
