PRESSURE-SENSITIVE ADHESIVE SHEET LAMINATE AND CONSTITUENT MEMBER LAMINATE OF IMAGE DISPLAY DEVICE

WIPO Patent Application WO/2016/088697

A1

Provided is a novel pressure-sensitive adhesive sheet laminate capable of minimizing contamination by foreign matter in the interface between an adhesive layer and a mold release layer and/or migrative transfer of a mold release agent to the adhesive layer in affixing a constituent member of an image display device, and that has excellent durability after affixing. A pressure-sensitive sheet laminate in which a substrate layer (layer III) is provided via a mold release layer (layer II) to one side or both sides of a photocurable adhesive resin layer (layer I) containing a photocurable adhesive resin, wherein the photocurable adhesive resin layer (layer I) in its uncured stated is formed from a resin composition containing a (meth)acrylic acid ester copolymer (A), a crosslinking agent (B), and a photoinitiator (C), the mold release layer (layer II) is formed from a resin composition containing an olefin polymer (D), and the photocurable adhesive resin layer (layer I) and the mold release layer (layer II) are formed by coextrusion.
