摘要： The invention relates to formation of a resin film excellent in adhesion with metal or other material and also excellent in alkaline resistance. The invention presents a water-based resin dispersion having an acid value of 0 to 15 obtained by emulsion polymerization of a monomer mixture comprising, in 100 parts by weight of .alpha.,.beta.-ethylenically unsaturated monomer, (1) 1 to 20 parts by weight of .alpha.,.beta.-ethylenically unsaturated monomer with a .beta.-ketoester group, (2) 0.05 to 5 parts by weight of crosslinking .alpha.,.beta.-ethylenically unsaturated monomer with two or more radically polymerizable groups, and (3) the rest of other .alpha.,.beta.-ethylenically unsaturated monomer than (1) and (2), by using a radically polymerizable emulsifier at a ratio of 0.2 to 10 parts by weight against the total of 100 pats by weight of the .alpha.,.beta.-ethylenically unsaturated monomer.

摘要： The invention provides a rust inhibiting technology for zinc-coated and uncoated steel which insures at least the equivalent of results obtainable by the technology using a Cr-containing coating composition. This method comprises coating a zinc-coated or uncoated steel substrate with a water-based resin composition comprising a carboxylated polyolefin resin and 70-0 part by weight of solid matter of at least one member selected from the group consisting of polyurethane resin, polyester resin, acrylic resin, epoxy resin, and alkyd resin as supplemented with 0.01-0.5 part by weight of phosphate ion based on 100 parts by weight of total solid matter of said water-based resin composition and adjusted to a pH value of not less than 7, either followed by heating the coated substrate at 50.degree.-250.degree. C. to dry the coat or preceded by heating said steel substrate at 50.degree.-250.degree. C. to let the then-applied coat dry spontaneously.
