Abstract
To provide an aqueous composition for aqueous coating that contains a polymerized substance of a N-vinyl carboxylic acid amide and that dries efficiently when used to produce a coating substance. A composition for aqueous coating liquid, comprising at least a copolymer of a N-vinyl carboxylic acid amide monomer and a monomer of a salt of an unsaturated carboxylic acid, and water, in which the molar ratio between the N-vinyl carboxylic acid amide monomer and the monomer of a salt of an unsaturated carboxylic acid is 7.0:93.0 to 93.0:7.0, and the weight-average molecular weight of the copolymer is 15,000 to 2,500,000.
