    Abstract: PROBLEM TO BE SOLVED: To provide a method for easily producing a (meth)acrylic ester by which a light color esterification product is obtained in high yield. SOLUTION: This method for producing a (meth)acrylic ester comprises esterifying acrylic acid and/or methacrylic acid with at least one compound having at least one alcoholic hydroxyl group while adding to the reaction system a hydrocarbon with a boiling point of 60-140 deg.C as a water azeotropic agent at 90-150 deg.C in the presence of an acidic esterification catalyst and a polymerization inhibitor, and after esterification, distilling the water azeotropic agent and excess (meth)acrylic acid off at 90-150 deg.C under a normal or reduced pressure, and if necessary, neutralizing the product obtained after distillation with at least one basic inorganic compound, wherein a copper (II) salt or a mixture composed of the copper (II) salt and a copper (I) salt to be deposited after esterification as a copper sulfide and separated is used as the polymerization inhibitor.

    Abstract: PROBLEM TO BE SOLVED: To obtain a mixture having a good ability to wet pigments, exhibiting a low yield point even at high viscosity, and being useful as a binder by constructing the mixture from a condensation resin constructed from a urea (derivative) and an acidic-CH aldehyde or ketone and a radiation-curable compound having a plurality of (meth)acryloyl groups. SOLUTION: This mixture is constructed from 10-90 wt. % condensation resin constructed from a urea (derivative) and an acidic-CH aldehyde or ketone and, optionally, HCHO, desirably comprising 50-100 wt.% acidic-CH aldehyde or ketone and 0-50 wt.% HCHO, constructed from an aldehyde or ketone (e.g. i-butylaldehyde) and desirably having a molar ratio of the urea (derivative) to the aldehyde or ketone of 1:4 to 1:10 and 90-10 wt. % radiation-curable compound desirably containing a polyester acrylate or a polyether acrylate having two or more, desirably, 2-20 (meth)acryloyl groups.

    Abstract: PROBLEM TO BE SOLVED: To obtain a polyurethane useful as a material for coating by reacting a specified polyhydric alcohol with an isocyanate. SOLUTION: This polyurethane which is suitable as a material or component of a coating material is obtained by reacting a prepolymer (a) obtained by reacting a polyhydric alcohol having more than one isocyanate-reactive hydroxyl group per molecule with an aromatic or aliphatic polyisocyanate in a ratio of the number of the isocyanatte-reactive hydroxyl groups to the number of the isocyanate groups of below 1 with an isocyanate selected from the group consisting of aromatic or aliphatic polyisocyanates (b) and a chain extender (2) obtained by reacting a polyhydric alcohol (a) with a compound (b) having an epoxy functional group and additionally an alcohol-reactive functional group, a reaction product (b) of the reaction product with an α,β-olefinically unsaturated carboxylic acid, and reacting this reaction product with an amine having a reactive prim. amino group.

    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.
