Abstract

An adhesive composition having excellent adhesiveness to a cycloolefin resin or the like. The adhesive composition of the present invention includes a polymer having a repeating unit derived from a polymerizable compound represented by formula (I): Y—N(Ar)(R) Formula (I), in which Ar represents an unsubstituted or substituted C6 to C14 aryl group or an unsubstituted or substituted C6 to C10 aryl C1 to C3 alkyl group; R represents an unsubstituted or substituted C1 to C6 alkyl group, an unsubstituted or substituted C3 to C6 cycloalkyl group, an unsubstituted or substituted C6 to C14 aryl group, or an unsubstituted or substituted C6 to C10 aryl C1 to C3 alkyl group; and Y represents a polymerizable functional group. In Formula (I), a substituent on Ar and a substituent on R can bond to form a divalent organic group.

First claim

The invention claimed is:

1. An adhesive composition, comprising a polymer having a repeating unit derived from a polymerizable compound represented by formula (I):
Y—N(Ar)(R)  Formula (I)

wherein
each of Ar and R represents, respectively,
a phenyl group which is substituted by either a benzyl group or a α,α-dimethylbenzyl group,
and

Y represents an acryloyl group or a methacryloyl, group.

2. The adhesive composition according to claim 1 , wherein the polymer is a homopolymer having a repeating unit derived from one type of polymerizable compound represented by formula (I).

3. The adhesive composition according to claim 1 , comprising:
the polymer, and
a polymerizable compound other than the polymerizable compound represented by formula (I).

4. The adhesive composition according to claim 1 , wherein the adhesive composition is an adhesive composition to be applied on a plastic substrate.

5. The adhesive composition according to claim 4 , wherein the plastic substrate is a polyolefin resin substrate.

6. The adhesive composition according to claim 4 , wherein the plastic substrate is a cycloolefin resin substrate.

7. The adhesive composition according to claim 4 , wherein the adhesive composition is a coating agent.

8. The adhesive composition according to claim 7 , wherein the coating agent is a primer.

9. The adhesive composition according to claim 4 , wherein the adhesive composition is an adhesive.

10. A formed body comprising a film obtained by applying and curing the adhesive composition as claimed in claim 1 on a substrate.

11. A polymer having a repeating unit derived from a polymerizable compound represented by formula (I):
Y—N(Ar)(R)  Formula (I)

wherein
each of Ar and R represents, respectively, a phenyl group which is substituted by either a benzyl group or a α,α-dimethylbenzyl group, and
Y represents an acryloyl group or a methacryloyl group.
