Document Type and Number:
WIPO Patent Application WO/2020/179601
Kind Code:
A1
Abstract:
Provided is a technique for preparing an excellent viscous composition having a pH of about 4-5.5, by using a copolymer obtained through polymerization of, after further adding a compound having two or more ethylenically unsaturated groups, a (meth)acrylic acid and a (meth)acrylic acid alkyl ester in which the number of carbon atoms in an alkyl group is 10-30. More specifically, provided is a viscous composition having a pH of 4-5.5 and a viscosity of 1000-50000 mPa・s and containing, for example: (A) a copolymer obtained through polymerization of 100 parts by mass of a (meth)acrylic acid, 0.5-5 parts by mass of a (meth)acrylic acid alkyl ester in which the number of carbon atoms in an alkyl group is 10-30, and 0.001-0.2 parts by mass of a compound having two or more ethylenically unsaturated groups; (B) a metal salt of a carboxylic acid; and (C) a carboxylic acid.
