Abstract: PURPOSE:To provide a water-dispersed paint which is suitable for use as a priming sealer for porous substrates and has excellent adhesion to topcoating paints, by emulsifying a soln. of an acrylic resin having a specified MW and a specified glass transition temp. in an org. solvent. CONSTITUTION:100pts.wt. acrylic resin having an MW of 3,000 to 30,000 and a glass transition temp. of not lower than 30 deg.C (e.g., a methyl methacrylate/ styrene copolymer) is dissolved in 25-150pts.wt. org. solvent. If desired, a surfactant, etc. are added thereto. While stirring in a homogenizer, etc., water is gradually added thereto to emulsify the mixture, thus obtaining the desired water-dispersed paint. The paint is suitable for use as a primer to flow PVC emulsion paints. When a porous substrate is coated with the paint as a priming sealer, the resin penetrates into the substrate to impart sufficient adhesion. Further, the paint is a water-dispersed one and hence it has no fear of causing environmental pollution or a fire by the evaporation of the org. solvent.

Abstract: PURPOSE:To provide a water-dispersible paint which has excellent adhesion to substrates and topcoat, flame retardance and water resistance and is freed from the problem of blistering, by emulsifying an org. solvent soln. of a chlorinate high-molecular compd. in the presence of a surfactant. CONSTITUTION:100pts.wt. chlorinated high-molecular compd. having an MW of 3,000-100,000, a chlorine content of 50-71wt% and a Tg of 60 deg.C or above (e.g., vinyl chloride/vinyl propionate copolymer) is dissolved in 25-200pts.wt. org. solvent having a b.p. of 80-200 deg.C (e.g., n-hexane), If desired, plasticizer (e.g., di-2-ethylhexyl phthalate), stabilizer (e.g., epoxidized soybean oil), etc. are added thereto to obtain an org. solvent soln. 1-20pts.wt. nonionic surfactant having an HLB of 10-18 (e.g., polyoxyethylene nonylphenyl ether) or anionic surfactant (e.g., sodium laurate) is added to 100pts.wt. said soln. Water is gradu ally added thereto while stirring to emulsify the soln.
