ABSTRACT:
Stable coating compositions are made from an aqueous dispersion of an alkyd resin (20-80% by weight of solids) neutralized to a pH of about 7.5 with ammonia or a volatile amine by forming therein an emulsion polymer (80-20% by weight of solids) of one or more vinyl monomers. When coated on a substrate, the compositions dry readily like vinyl emulsion polymers but with a glossy and durable finish like the relatively cheap alkyds. Free radical catalysts, e.g., peroxides, may be encapsulated during the emulsion polymerization and remain stable until evaporation of water.
