Document Type and Number:
WIPO Patent Application WO/2013/027657
Kind Code:
A1
Abstract:
An adhesive composition is obtained by blending a crosslinking agent and an organic acid into an acrylic resin that is a copolymer of the components (A-1)-(A-3) described below, and the adhesive composition is formed into a sheet shape, thereby obtaining an adhesive sheet.
(A-1) 94.8-99.89% by weight of a (meth)acrylic acid ester that is represented by formula (I) (wherein R1 represents a hydrogen atom or a methyl group, and R2 represents an alkyl group or an aralkyl group, which may be substituted by an -O-(C2H4O)n-R3 group (wherein n represents 0 or an integer of 1-4 and R3 represents an alkyl group or an aryl group))
(A-2) 0.1-5% by weight of a (meth)acrylic monomer having a hydroxyl group
(A-3) 0.01-0.2% by weight of a carboxyl group-containing (meth)acrylic ester that is represented by formula (II) (wherein R4 represents a hydrogen atom or a methyl group, and A represents a C2-4 divalent group)
