Abstract
Emulsion type rust-preventive baking composition which comprises a polymer emulsion such as an aqueous acrylic resin emulsion and a heat-fusible organic filler having a melting or softening point within the range of 40.degree.-250.degree. C. which is higher by at least 10.degree. C. than the lowest film-forming temperature of the polymer emulsion, as incorporated in the polymer emulsion. When the emulsion type rust-preventive baking composition obtained by the mixture is coated on reinforcing steel rods or the like treatment targests and baked, the heat-fusible organic filler melts and fills pores in the rust-preventive coat film, whereby the coat film is rendered close and compact to produce excellent rust-preventive effect.
