Title:
ADHESIVE, BONDED OBJECT AND BONDED OBJECT MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/021521
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an adhesive which has high adhesive strength in adhesion between a polyvinyl alcohol-containing film and a substrate and excellent curing rate, and with which bonded objects with reduced warping can be obtained. The present invention is an adhesive for bonding a polyvinyl alcohol-containing film to a substrate and comprises a (meth)acrylic polymer (X) with actinic ray curable groups and a non-(meth)acrylic polymer (X) compound (Y) with actinic ray curable groups. Another present invention is an adhesive for bonding a polyvinyl alcohol-containing film to a substrate comprising a polymer (X') with actinic ray curable groups and a non-polymer (X') compound (Y') with actinic ray curable groups and for which the crosslink density determined from the storage elastic modulus of a rubber-like flat region obtained by measuring dynamic viscoelasticity after curing is 0.4 mol/L to 2 mol/L.
