ABSTRACT:
A resin composition for a water-repellent coating which is excellent in adhesion to a substrate and weathering resistance and has a high hardness equivalent to that of a hard coating and excellent acid resistance, which can exhibit these properties in spite of a low fluorine content, the composition containing a polymer (A) formed from 20 to 80% by weight of a fluorine-containing monomer (a) having a carbon-carbon unsaturated double bond and a perfluoroalkyl group, 20 to 80% by weight of a monomer (b) having a carbon-carbon unsaturated double bond and a crosslinkable functional group and 0 to 30% by weight of a monomer (c) having a carbon-carbon unsaturated double bond other than the monomers (a) and (b), and a polymer (B) formed from 20 to 100% by weight of a monomer (b) having a carbon-carbon unsaturated double bond and a crosslinkable functional group and 0 to 80% by weight of a monomer (c) having a carbon-carbon unsaturated double bond other than the monomer (a) and (b), and a water-repellent coating composition which is a solution of the above resin composition in a solvent.
