SOLUTION: For manufacturing a base coat, an aqueous composition contains (i) at least one aqueous polymer dispersion wherein a polymer P has a glass transition temperature lower than 0 deg.C, and (ii) at least one water-soluble bivalent metal cation. Here, from 80 to 99.5 mass % at least one monoethylenically unsaturated, hydrophobic monomer A, from 0.5 to 10 mass % at least one ethylenically unsaturated monocarboxylic acid or dicarboxylic acid or anhydride thereof as a monomer B and, occasionally, from 0 to 10 mass % at least one ethylenically unsaturated monomer C other than monomers A and B are polymerized and introduced into the aqueous polymer dispersion, and the total mass content of monomers A, B and C is 100 mass %.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject coating agent capable of forming a coat which has excellent wet abrasion resistance and hardly becomes dirty without using an expensive production method by including a specific aqueous polymer dispersion, inorganic pigment, etc., and bringing the pigment volume concentration to at least a specific value without essentially including any volatile organic solvent. SOLUTION: This coating agent is obtained by including (A) at least one kind of an aqueous polymer dispersion capable of forming a thin film at room temperature and containing at least one kind of a polymer made from (i) 80-99.95 mass % of at least one kind of monomer selected from e.g. acrylic esters each having a 2-20C alkanol or 5-10C cycloalkanol and (ii) 0.05-10 mass % of at least one kind of monomer selected from e.g. ethylene-based unsaturated carboxylic acids, (B) at least one kind of inorganic pigment or the like, (C) 0.05 to =10.

Abstract: PROBLEM TO BE SOLVED: To obtain a coated product not generating while powder (ausbluehens) and not changing its strength and visual appearance with water by coating a molded product with a radiation-curable prepared product containing a polymer having ethylenic unsaturated double bonds and subsequently curing the coated product by the irradiation of UV light or electron beams. SOLUTION: The content of ethylenic unsaturated double bonds is usually 0.01-1.0 mole/100 g of polymer. The ethylenic unsaturated double bond is preferably a group of the formula: P-Z-X-CR =CHR [X is a single bond, CH2 or CO; Z is a single bond, O or NH; P is a 2-10C organic group or a single bond; R is H or methyl group; R is H, methyl group, phenyl group when X is CO or CO2 Y (Y is H or a 1-4C alkyl group)]. Silicones, polyurethanes, polyesters, polyethers, epoxy resins, melamine resins and methacrylate ester copolymers which have ethylenic unsaturated groups, respectively, are important as the polymer.

Abstract: PROBLEM TO BE SOLVED: To obtain a water-based preparation that can be used in mineral formed products and gives a coating layer having low water absorption and causing no change giving adverse effects on its strength and optical appearance even after exposure to damp for a long time by using a polymer having a specific glass transition temperature and an anionic emulsifier. SOLUTION: The objective preparation comprises (A) at least one selected from polymers P that are composed of an ethylenically unsaturated monomer M, disperse in aqueous phase, have a glass transition point ranging from -25 to +80 deg.C, as a coating layer-forming component, (B) at least one selected from anionic emulsifiers consisting of salts of the formula (Alk is a 10-18C saturated alkyl; Et is 1,2-ethylene; (n) is 20-40; M+ is a monovalent cation or a cation equivalent) or a mixture thereof. In a preferred embodiment, at least one kind of nonionic emulsifier is contained in addition to the salt of the formula, and the total amount of the emulsifier is 0.2-10 wt.% based on the component A.

Abstract: PROBLEM TO BE SOLVED: To ensure high stability under weathering conditions and to impart very good surface characteristics by coating a mineral molding with a 1st preparation contg. a binder copolymer and an inorg. pigment and then coating the coated molding with a 2nd preparation contg. a binder copolymer and, if desired, an inorg. pigment. SOLUTION: The above preparations are thin film forming aq. preparations. The above copolymers P1, P2 consist of monomers A, B and, if desired, a monomer C. The monomer A is a vinyl arom. compd. A1 and/or a 1-C alkanol methacrylic ester A2. The monomer B is an ester of an α,β-ethylenically unsatd. carboxylic acid having a 1-12C alkanol and different from the ester A2 and/or a vinyl ester of an aliphatic carboxylic acid. The monomer C is an α,β- ethylenically unsatd. monomer other than the monomers A, B. The volume concn. of the pigment in the 1st preparation is higher than that in the 2nd preparation by at least 10. The glass transition temp. of the copolymers is in the range of -25 to +80 deg.C.
