Title:
(METH)ACRYLIC RESIN COMPOSITION, IMIDIZED (METH)ACRYLIC RESIN COMPOSITION, AND FILM OBTAINED BY MOLDING THEM
Document Type and Number:
WIPO Patent Application WO/2008/056769
Kind Code:
A1
Abstract:
Disclosed is a (meth)acrylic resin composition having a carboxylic acid group produced by heating a (meth)acrylic resin (C) which is obtained by polymerizing a monomer mixture (A) containing 80-99% by weight of a (meth)acrylic acid linear alkyl ester and 1-20% by weight of a (meth)acrylic acid tertiary butyl ester in the presence of an acrylic acid ester-based crosslinked elastic particle (B). The acrylic acid ester-based crosslinked elastic particle (B) is obtained by blending and polymerizing 0.5-5 parts by weight of a polyfunctional monomer having two or more non-conjugated double bonds per a molecule with 100 parts by weight of a monomer mixture containing 50-100% by weight of an acrylic acid alkyl ester monomer and 0-50% by weight of a methacrylic acid alkyl ester monomer. This (meth)acrylic resin composition enables to produce a film having excellent chemical resistance (particularly, resistance to sunscreen compositions).
