Title:

LAMINATE BODY AND ACTIVE-ENERGY-RAY-CURABLE INK COMPOSITION USING SAME

Document Type and Number:

WIPO Patent Application WO/2015/005453

Kind Code:

A1

Abstract:

　Provided is a laminate body having a decorative layer formed on the surface thereof, having excellent cracking resistance and external appearance retention even in an environment such as one in which the substrate undergoes repeated expansion and contraction. A laminate body on which a decorative layer, which is a cured film made from an active-energy-ray-curable ink composition, is formed on a stretchable substrate, wherein the cured film contains a cured product comprising: a monofunctional monomer (monomer (A)) having a glass transition point at or below -30°C; and an alkylene-oxide-modified tri- or higher-functional monomer (monomer (B)) in which the number of alkylene oxide modifications/number of functional groups, which is the ratio of the number of alkylene oxide modifications and the number of functional groups, is 3 or greater, the number of cracks in a test piece of the cured film after prescribed repeated tensile testing being 3 or less.
