PURPOSE:To obtain the subject composition outstanding in adherability, gloss, clearness, chemical resistance and weatherability, by spiking a specific coating composition for polyurethane resin molded products with an acidphosphoric ester compound. CONSTITUTION:The objective composition can be obtained by spiking (A) a coating composition for polyurethane resin molded products, comprising a polyesterpolyol resin and/or acrylpolyol resin and aminoaldehyde resin and furthermore, pref. a pyrrolidone (derivative) and epoxy group-contg. compound with (B) pref. 0.005-0.10gram equivalent, based on 100 pts.wt. of the solid resin component of the component A, of an acid-phosphoric ester compound [pref. acidphosphoric ester of formula I (R1 and R2 are each H or 1-20C monovalent organic group, one or both of them being organic group) or acidphosphorous ester of formula II]. |
