Claims12
An aqueous emulsion composition which is the product of emulsion polymerization of at least one radical-polymerizable unsaturated monomer in the presence of a water-soluble resin having a graft-polymerizable unsaturated group in the side chain in water or a mixture consisting essentially of water and a water-miscible organic solvent, said water-soluble resin being a water-soluble resin formed by
- (A) co-polymerizing
- (i) a monomer containing one radical-polymerizable unsaturated group of the formula ##STR11## wherein R.sub.4 is hydrogen or methyl, and R.sub.5 is ##STR12## a phenylene group or a lower alkenylene group, wherein R.sub.6 is hydrogen, methyl or ethyl,
- and at least one graft-polymerizable unsaturated group in one molecule,
- (ii) an .alpha.,.beta.-ethylenically unsaturated acid, and/or a monoester between a polyalkylene glycol and acrylic or methacrylic acid, and
- (iii) another radical-polymerizable unsaturated monomer having a Q value, in the Q-e theory, of at least 0.1, and
- (B) neutralizing the resulting copolymer in the presence of the radical-polymerizable unsaturated monomer.
A coating composition comprising the aqueous emulsion composition set forth in any one of claims 10-15, 17, 18, 11 and 1 as a film-forming component.
