Abstract
PURPOSE: To obtain titled resin suitable as a material for powder coatings, by reacting an OH group-containing polyester resin with an intermediate having both an epoxy group and an ester group prepared by the reaction between a polyepoxy compound and a monoalkyl terephthalate.
CONSTITUTION: A polyepoxy compound having at least two epoxy groups, e.g., bisphenol A-derived epoxy resin, is reacted with a monoalkyl terephthalate, e.g., monomethyl terephthalate, to obtain an intermediate having both an epoxy group and an alkyl ester group. This intermediate is reacted with an OH group-containing polyester resin at a weight ratio of 28/80W80/20 in the presence of a transesterification catalyst to obtain an epoxy group-containing polyester resin.
USE: This resin is combined with a curing agent such as sebacic acid, dodecanedioic acid, a carboxyl group-containing polyester resin or a carboxyl group-containing acryl resin, to obtain a powder coating which can be cured without evolution of volatile matter.
