| description | PURPOSE:To provide the subject composition causing no spray and reversion unevennesses, excellent in coating workability and durability, useful for e.g. metallic base coating, comprising each specific graft copolymer and modified vinyl copolymer and a polyisocyanate compound. CONSTITUTION:The objective composition comprising (A) a graft copolymer 60-120 in hydroxyl value prepared by copolymerization between (1) 10-30wt.% of a macromonomer, (2) 0-30wt.% of styrene and (3) 40-90wt.% of another ethylenically unsaturated monomer, (B) a modified vinyl copolymer prepared by copolymerization between (a) 5-75wt.% of cellulose acetate butyrate and (b) 95-25wt.% of a vinyl monomer mixture of 1-50wt.% of at least one kind of OH-contg. functional vinyl monomer and 99-50wt.% of another vinyl monomer, and (C) a polyisocyanate compound, pref. in a weight ratio A/B of (10:90) to (90:10). The amount of the component C to be incorporated is pref. such that the equivalent ratio NCO/OH be 0.52 to 2.0 (where, OH is the sum of the respective hydroxyl groups in the components A and B). |
