Claim:
1. An aqueous liquid composition comprising: a water-based medium containing water; at least one of chitosan and a chitosan derivative selected from the group consisting of hydroxyalkyl chitosans, carboxyalkyl chitosans, carboxyacyl chitosans, succinyl chitosans, and cationized chitosans; and a polymeric acid; wherein the aqueous liquid composition has a pH of not higher than 4.5; wherein the polymeric acid is at least one polymeric acid selected from the group consisting of polyacrylic acid having molecular weight of 150,000 or less, polymaleic acid, phthalocyanine polycarboxylic acid, phytic acid, hexametaphosphoric acid, polyphosphoric acid, polymethacrylic acid and copolymers thereof, styrene-maleic acid copolymer, isobutylene-maleic acid copolymer, vinyl ether-maleic acid copolymer, pectic acid, polyglutamic acid, polymalic acid, polyaspartic acid, and acrylic acid-maleic acid-vinyl alcohol copolymer; wherein a content of the at least one of chitosan and chitosan derivative in the aqueous liquid composition is 0.1 to 40 parts by mass per 100 parts by mass of the aqueous liquid composition; and wherein a content of the polymeric acid in the aqueous liquid composition is 1 to 40 parts by mass per 100 parts by mass of the aqueous liquid compostion.
