<P>PROBLEM TO BE SOLVED: To obtain polymer aqueous dispersion used for a brighter for floor by forming a film excellent in water resistance, washing resistance and release property. <P>SOLUTION: A polymer aqueous dispersion of a polymer is obtained by emulsion polymerization of a monomer mixture which includes at least an aromatic vinyl compound monomer (A) and a (meth)acrylic acid monomer (B), the content of the (A) component being 65-90 wt% of the total monomer, in an aqueous medium. The polymer aqueous dispersion having predetermined characteristics is used. <P>COPYRIGHT: (C)2013,JPO&INPIT |
