Abstract

PURPOSE: The titled composition, prepared by synthesizing from a specific high polymeric diol, alicyclic diisocyanate hydrazine and alicyclic diamine, having improved dyeability, color fastness, dye preventing property on dye transfer and solvent resistance, etc. and suitable for artificial leather.
CONSTITUTION: A composition synthesized from (A) a high polymeric diol, consisting of a diol containing a polyeth polyoxyethylene chain (or a mixture diol with a diol containing no polyoxyethylene chain) with a polyoxyethylene chain content of 5W50wt% based on the total high polymeric diol and having an average molecular weight of 300W5,000, (B) an alicyclic diisocyanate, (C) hydrazine and (D) an alicyclic diamine. The component (B) is isophorone diisocyanate or the component (D) is isophoronediamine, or the component (B) is isophorone diisocyanate and the component (D) is isophoronediamine. The molar ratio of the total amounts of the components (C) and (D) to the comp component (A) is 0.5W 4.0, and the molar ratio of the component (D) to the component (C) is 4.0W20.
