Abstract

A urethane compound (A) including units formed from (A1) an isocyanate and (A2) a long-chain alcohol represented by the formula HO—Z(Y—R)n [wherein the R moieties are each independently —O—, —NH—, —O—C(═O)—, —NH—C(═O)—, —C(═O)—NH—, —O—C(═O)—NH—, —NH—C(═O)—O—, —NH—C(═O)—NH—, —NH—S(═O)2—, —S(═O)2—NH—, —NH—(CH2)m—NH—S(═O)2—, —NH—(CH2)m—S(═O)2—NH—, etc. (m is an integer of 1-5), Z is a direct bond or a di- or trivalent hydrocarbon group having 1-5 carbon atoms, and n is 1 or 2]. Also disclosed is a urethane mixture containing the urethane compound (A), and at least one selected from the polyisocyanate (A1), the long-chain alcohol (A2), a blocking agent (A3) and an alcohol compound (A4); an aqueous urethane composition; a method for producing the aqueous urethane composition; a method of treating a substrate; and a treated textile product.
