<P>PROBLEM TO BE SOLVED: To provide a silicone resin aqueous dispersion excellent in dispersion stability and giving a dry film excellent in water resistance. <P>SOLUTION: There is provided a silicone resin aqueous dispersion which comprises a silicone resin (A) having an amino group, or having a sulfo group and/or a carboxyl group, and water, and contains no surfactant for dispersing the (A). The amine value or the acid value of the (A) is preferably 5-300. At least a part of the amino group is neutralized with at least one neutralizer selected from the group consisting of formic acid, acetic acid, propionic acid and carbonic acid, and at least a part of the sulfo group and/or the carboxyl group is preferably neutralized with at least one neutralizer selected from the group consisting of ammonia, monomethylamine, monoethylamine, dimethylamine, diethylamine, trimethylamine, triethylamine and ethyldimethylamine. <P>COPYRIGHT: (C)2012,JPO&INPIT |
