RUSH PRODUCT HAVING FILM OF POLYURETHANE RESIN AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a rush product having flexible and dry touch essentially possessed by rush itself and excellent in durability such as abrasion resistance or fastness to friction. SOLUTION: This rush product having the abrasion resistance is characterized in that the rush product has a film of a polyurethane resin which is an aqueous polyurethane resin obtained by reacting a compound having an anionic hydrophilic group and >=2 active hydrogens and an active hydrogen-containing compound containing at least a high-molecular weight polyol with an organic polyisocyanate compound and extending the chain of the resultant isocyanate group-terminated prepolymer with at least one chain extender selected from the group consisting of a water-soluble polyamide, hydrazine and a derivative thereof.
