Document Type and Number:
WIPO Patent Application WO/2018/169031
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a urethane (meth)acrylate polymer which enables the achievement of a coating film that prevents bleeding of an ultraviolet absorbent, while having excellent weather resistance, scratch resistance and transparency; and a curable composition which contains this urethane (meth)acrylate polymer. The present invention also addresses the problem of providing a laminate and a decorative film, each of which has a layer that is formed of a cured product of the above-described urethane (meth)acrylate polymer or a curable composition containing the above-described urethane (meth)acrylate polymer on the surface. The problems are solved by a urethane (meth)acrylate polymer which has a chemical structure represented by formula (1). (In the formula, A represents a single bond or a methylene group, an alkylene group, an -O- group, an -NH- group, an -S- group, an -SO- group or an -SO2- group, each of which may have a substituent; each of R1, R2, R3 and R4 independently represents a hydrogen atom, an alkyl group, an alkoxy group, an aryl group or a halogen atom; and each of R5 and R6 independently represents an alkylene group, an alkoxylene group or an arylene group.)
