Abstract

PURPOSE: To prepare the title solution non-corrosive to metals, having improved storage stability, and suitable for the coating of synthetic leather, etc., by adding an epoxy compound and an acidic compound to a polyurethane solution.
CONSTITUTION: A solution composed of (A) a polyurethane solution (pref. a solution of polyurethane elastomer free from free isocyanate group), (B) (pref. 0.0001W 5wt% of) an acidic compound such as carboxylic acid (or its halide or anhydride) pref. having an ionization constant of 5×10-1W1×10-6 at 25°C, (C) (pref. 0.01W 1wt% of) an epoxy compound (pref. a water-soluble compound having an epoxy equivalent of ≤500) and optionally (D) (pref. 0.01W0.5wt% of) a tert-amine such as pyridine.
