| abstract | 1476584 Aqueous coating composition KANSAI PAINT CO Ltd 20 March 1975 [28 March 1974] 11595/75 Heading C3P An aqueous coating composition comprises an aqueous medium and a binder resin neutralized with a base dispersed therein, the binder resin being a copolymer consisting of 7À5-95% by wt. of (A) a monomer prepared by casting 0À8- 1-2 moles of at least one glycidyl ester of acrylic acid and methacrylic acid with 1À0 mole of at least one fatty acid selected from drying oil fatty acid and semi-drying oil fatty acid of which from 0-30% by wt. based on the total fatty acid is an unsaturated fatty acid having conjugated double bonds, 5-20% by wt. of (B) an α,#- ethylenically unsaturated acid and/or maleic anhydride and 0À01-87À5% by wt. of (C) an unsaturated monomer containing substantially no carboxyl group and having a Q value of at least 0À1 as determined by Q-e theory. The copolymer may have an acid value of 25-150 and an average molecular weight of 500- 80,000. The copolymer may be produced by conventional techniques especially using methods employing a solvent in which the copolymer obtained is soluble and which is miscible with water. Suitable sources are alcohols, glycols, alkyl ethers of glycols, glycol acetates, diacetone alcohol, dioxane, tetrahydrofuran, acetone and dimethylformamide. The amount of such solvent is usually 15-90% by wt. of the copolymer solution. The copolymer prepared is rendered soluble or dispersible in water by neutralizing with conventional bases. The neutralized is then dispersed in an aqueous medium to produce the aqueous coating composition which may be used specifically to coat steel plates. Conventional pigments, dispersants, stabilisers and defoamers may also be added. The specific Examples describe the polymerization of:- the monomer obtained by reacting linseed oil fatty acid and glycidyl methacrylate, n-butyl methacrylate and acrylic acid in ethylene glycol monobutyl ether (1b) (1c): the product of safflower oil fatty acid and glycidyl methacrylate with:- acrylic acid and styrene (2b); n-butyl methacrylate and methacrylic acid (2c); n-butyl methaorylate and acrylic acid (2d); and styrene, lauryl methacrylate and methacrylic acid (2f) all in ethylene glycol monobutyl ether; methyl methacrylate, n-butyl methacrylate and acrylic acid in ethylene glycol monoethyl ether (2e): the product of soybean oil fatty acid and glyoidyl methacrylate with styrene, n-butyl methacrylate and acrylic acid in diethylene glycol monobutyl ether (3b) or ethylene glycol monobutyl ether (3c): the product of safliower oil fatty acid and glycidyl acrylate with styrene and methacrylic acid in ethylene glycol monobutyl ether. |
