PROBLEM TO BE SOLVED: To solve the problems that non-solvent-type water-based coatings or paints widely used are likely to be stained due to their poor stain resistance, be discolored due to their poor weather resistance, and be peeled out and dissolved due to their poor water resistance. SOLUTION: A stain-proof coating agent prepared by making an amphoteric polymeric emulsion adsorb anionic colloidal silica to disperse the silica in the emulsion, the emulsion being obtained by adding a cationic property to the particle surface of an anionic and/or nonionic resin emulsion having negative surface electric potential through neutralization or quaternary ammonium salt formation of a group introduced by a specified monomer into a carboxylated seed latex. The coating agent is applied on a hydrophobic material with a contact angle of 60° or more. COPYRIGHT: (C)2005,JPO&NCIPI
