    Abstract: PROBLEM TO BE SOLVED: To provide a smoothing agent for powder coating, which can impart good smoothness to the powder coating, when compounded with the powder coating in a small amount. SOLUTION: This smoothing agent for the powder coating is characterized by comprising a copolymer obtained by copolymerizing a polymerizable unsaturated double bond-having dibasic acid ester (A) with an alkyl acrylate and/or an alkyl methacrylate (B), wherein the copolymer is obtained by copolymerizing the component (A) in an amount of 2 to 65 wt. % based on the total amount of all the monomers with the component (B) in an amount of 35 to 98 wt. % and has a number-average mol. wt. of 1,000 to 60,000.

    Abstract: PROBLEM TO BE SOLVED: To provide a coating method that is an inexpensive coating process capable of providing a coating composite material having good adhesion, cutting resistance, and smoothness and can achieve coating by a wet-on-wet-on-wet ("WOWOW") method. SOLUTION: In this method, composite coating is formed on a substrate. The method includes the step of (A) coating an aqueous primary coating composition onto a part of a surface of a substrate to form an uncured primary coating thereon. The primary coating composition comprises the following components: (1) at least one heat curable dispersion containing polymeric fine particles having functionality adapted to react with a crosslinking material; and (2) at least one crosslinking material. The fine particle contains (a) at least one acid functional reaction product of ethylenically unsaturated monomers and (b) at least one hydrophobic polymer. COPYRIGHT: (C)2006,JPO&NCIPI
