Title:
PHOTOCURABLE PRESSURE-SENSITIVE ADHESIVE COMPOSITION, PHOTOCURABLE PRESSURE-SENSITIVE ADHESIVE LAYER, AND PHOTOCURABLE PRESSURE-SENSITIVE ADHESIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2011/068117
Kind Code:
A1
Abstract:
Provided is a photocurable pressure-sensitive adhesive composition which does not cause squeeze-out under ordinary temperature and pressure conditions and exhibits sufficient initial tack via drying and crosslinking and which is easily curable by light irradiation and can form a curable pressure-sensitive adhesive layer having high peel resistance. Also provided are a photocurable pressure-sensitive adhesive layer and a photocurable pressure-sensitive adhesive sheet.
A photocurable pressure-sensitive adhesive composition which comprises both a graft polymer obtained by grafting a chain that contains a monomer bearing a cyclic ether group onto a (meth)acrylic polymer that contains 0.2 to 10wt% of hydroxyalkyl(meth)acrylamide monomer units, and a cationic photopolymerization initiator; a photocurable pressure-sensitive adhesive layer using the same; and a photocurable pressure-sensitive adhesive sheet.
