Abstract

PURPOSE: Title solution composition that is made by mixing two kinds of specific polyurethane elastomer solutions, thus having high storage stability and giving synthetic leather with high moisture permeation, hydrolysis resistance, flexibility, lightness and uniformly porous structure.
CONSTITUTION: (A) A clear solution of less than 0.05 turbidity that is made by dissolving 20W40wt% of a polyurethane elastomer containing more than 70wt% of polyteteramethyleneether glycol and less than 30wt% of high-polymer diol as polyalkylene glycol or polylactone glycol in a water-miscible organic solvent is mixed with (B) another clear solution of less than 0.05 turbidity that contains 20W40wt% of another polyurethane elastomer containing a polymethylene adipate diol as the high polymer diol component to give the objective solution of 20W38wt% total polyurethane elastomer concentration and 0.2W1.5 turbidity.
