Document Type and Number:
WIPO Patent Application WO/2021/157583
Kind Code:
A1
Abstract:
Provided is a composition having improved storage viscosity. A composition according to one mode of the present invention contains a (meth)acrylic copolymer (A') and epoxy compound (C). The molecule of the (meth)acrylic copolymer (A') includes a XY diblock structure or a XYX triblock structure within the molecule. The average number of repeating units derived from a (meth)acrylic acid ester monomer that has an alkoxysilyl group and that is included in an X-block, is 1.0 or more. Repeating units derived from a (meth)acrylic acid ester monomer that has an alkoxysilyl group and that is included in a Y-block account for 0-3 wt% with respect to the weight of all repeating units included in the Y-block. The molecule weight distribution (Mw/Mn) of the (meth)acrylic copolymer (A') is 1.8 or less.
