摘要：
Thermosetting bidder composition for coating, comprising:
(I) (1) A non-acidic resinous compound, saturated, molecular weight at least 900, alcoholic hydroxyl content at least 0.2 eq./100 g; (2) as cross-linking agent a non-acidic polyester of a polycarboxylic acid, having more than one beta-hydroxyl ester group per molecule, at least one of components (1) and (2) having an alcoholic hydroxyl functionality of more than 2, and (II) as curing catalyst a transesterification-promoting metal compound which is insoluble in liquid hydrocarbons. The compositions can be used in solvent-based lacquers and paints, in coating powders, aqueous powder suspensions, in aqueous coating compositions for cathodic electrodeposition; for aqueous compositions component (I) (1) is preferably an epoxy resin/amine adduct.
