Title:

ACRYLIC ADHESIVE COMPOSITION AND ACRYLIC ADHESIVE TAPE

Document Type and Number:

Japanese Patent JP2014074179

Kind Code:

A

Abstract:

To improve adhesiveness of an acrylic adhesive tape.

An acrylic adhesive composition includes: an acrylic polymer (A); and a (meth)acrylic polymer (B) including a (meth)acrylic monomer having a tricyclic or higher alicyclic structure as a monomer unit, with weight average molecular weight of 1000 or more and less than 30000. The (meth)acrylic monomer is, for instance, a (meth)acrylic acid ester expressed by a following general formula (1): CH₂=C(R¹)COOR² (1). [In the formula (1), R¹ denotes a hydrogen atom or a methyl group, and R² denotes an alicyclic hydrocarbon group having a tricyclic or higher alicyclic structure.]
