Abstract:
1. An artifical leather fabricated by infiltrating an aqueous resin dispersion (A) into a fibrous substrate, which satisfies the following requirements (I) to (IV): (I) the aqueous resin dispersion (A) comprises essentially a main resin (a) stabilized with a surfactant, a polymer (b) having a polyoxyethylene group in its side chains, and a surfactant (c); (II) the main resin (a) comprises an urethane resin (a1) and/or an urethane-acrylic composite resin(a2), and the resin skeleton contains from 1 to 10 mmols of a carboxyl group per 100 g of the resin; (III) the polymer (b) is obtained through polymerization of a polyoxyethylene group-having ethylenic unsaturated monomer (b1) and any other ethylenic unsaturated monomer (b2) in a ratio by mass (b1)/(b2)=60/40 to 100/0; (IV) the percentage, % by mass (α) of the polyoxyethylene group in the polymer (b) and the number of mols (β) of amino groups per gram of the polymer (b) satisfy the following formula (1):
