Abstract
An adhesive composition of the present application includes the following components (A) to (C): (A) a radically polymerizable compound; (B) a polymer having a weight-average molecular weight of 35,000 to 110,000 and having a repeat unit derived from a polymerizable compound of formula (I) (wherein X1 and X2 each independently represent a C7 to C20 alkyl group or a C7 to C20 alkoxy group, n represents 0 or 1, Z1 and Z2 each independently represent a single bond or a Cl to C3 alkylene group, each R independently represents an organic group or a halogeno group, m1 and m2 each independently represent any integer of 0 to 4, and Y represents a polymerizable functional group); and (C) a radical polymerization initiator.

An adhesive composition comprising the following components (A) to (C):
- (A) a monofunctional or polyfunctional (meth)acrylate, (meth)acrylamide or an oligomer thereof;
- (B) a polymer having a weight-average molecular weight of 35,000 to 110,000 and having
- a repeat unit derived from a polymerizable compound of formula (I′):
- wherein
- X1 and X2 each independently represent a C7 to C20 alkyl group or a C7 to C20 alkoxy group,
- n represents 0 or 1,
- Z1 and Z2 each independently represent a single bond or a C1 to C3 alkylene group, and
- Y represents an acryloyl group or a methacryloyl, and
- a repeat unit derived from C1-12 alkyl (meth)acrylic acid ester, wherein
- the molar ratio between the repeat unit derived from a polymerizable compound of formula (I′) and the repeat unit derived from C1-12 alkyl (meth)acrylic acid ester is 95:5 to 80:20;
- and
- (C) a radical polymerization initiator, wherein
- the component (B) is 1 to 80 parts by mass with respect to 100 parts by mass of the component (A), and
- the component (C) is 0.01 to 10 parts by mass with respect to 100 parts by mass of the component (A).
