RESIN COMPOSITION FOR NON-WATER DISPERSION TYPE COATING MATERIAL, AND COATING MATERIAL

PROBLEM TO BE SOLVED: To improve soil resistance and waterproof property simultaneously in a non-water dispersion type coating material. SOLUTION: This resin composition for the non-water dispersion type coating material consisting of (A) a copolymer dissolvable in an organic solvent, and (B) a copolymer non-dissolvable in the organic solvent is provided with that the copolymer (B) is obtained by polymerizing (a) a component consisting of at least one of (a-1) a fluorine-containing monomer and (a-2) a polysiloxane-containing monomer, (b) a hydrophilic monomer without having a dissociative group and (c) a cross-linking monomer, and also the ratio of the (b) to (a) components is (b/a)=(67 to 1,200 pts.wt.)/(100 pts.wt.). Since the copolymer (B) as the core is constituted by the components (a) to (c), and also the weight balance of the components (a) to (b) is properly set, both of the improvement of the soil resistance and insurance of the waterproof property by making the coated film surface as hydrophilic can be attained by the above weight balance and cross-linking effects.
