Abstract: A photocurable primer composition containing (A) an acrylic resin having through an urethane linkage a polymerizable unsaturated group on its side chain and containing the polymerizable unsaturated group in an amount of 0.2 to 2.0 mol/kg in a solid content of the resin (A), (B) an urethane (meth)acrylate oligomer containing at least one polymerizable unsaturated group in one molecule, and (E) a photopolymerization initiator, and a coating method.

Abstract: A repair coating method which comprises coating a photocurable processing composition (I) onto a damaged area of a substrate to form a processed layer, followed by coating a colored base coating composition (II) onto the processed layer to form a colored base layer, and coating a photocurable clear composition (III) onto the colored base layer to form a clear layer.

Abstract: A coating composition comprising(A) a film-forming binder resin,(B) a volatile organic liquid diluent dissolving the film-forming binder resin (A) and(C) fine particles of a polymer which does not dissolve in a solution of the binder resin (A) in the diluent (B) but are dispersed stably in said solution, andthe fine polymer particles (C) being fine particles of gelled polymer obtained by emulsion polymerization of(a) a polymerizable monomer having at least two radical-polymerizable unsaturated groups in the molecule, and(b) a radical polymerizable unsaturated monomer other than the monomer (a),in the presence of a reactive emulsifier having an allyl group in the molecule.

Abstract: Disclosed is an automotive coating composition comprising (i) a basal resin which is either (a) a copolymer containing a specific polysiloxane macromonomer having two or more functional groups selected from the class consisting of hydroxyl and alkoxy groups per molecule and a number average molecular weight of 400 to 100,000 and an oxirane group-containing vinyl monomer as comonomer units or (b) a mixture of a polymer (I) containing said polysiloxane macromonomer as an essential monomer unit and a polymer (II) containing an oxirane group-containing vinyl monomer as an essential monomer unit and (ii) a chelate compound selected from the class consisting of aluminum chelate compounds, titanium chelate compounds and zirconium chelate compounds.

Abstract: An organic solvent-type coating composition comprising as a main film-forming component a modified polyolefin composed of an adduct of a monoepoxy compound with an polyolefin having maleic acid or its anhydride grafted thereto, and a method of coating a plastic material using the coating composition.

Abstract: Discharge lamps are connected to a commerical alternating current power supply through an impedance for blocking high frequency signals and an impedance compensating for the negative resistance of the discharge lamps. The discharge lamps are also connected to the commercial alternating current power supply through a rectifier and oscillator circuit, a voltage signal is generated including the commercial alternating current voltage superposed on a high-frequency, high-voltage signal from the oscillator. This voltage signal is applied to the discharge lamps to energize the same and maintain the lamps in a lighted condition.
