Abstract
Abstract A thermosetting binder composition for coating, comprising: (I) (1) A non-acidic resinous saturated compound having a molecular weight of at least 900, and an alcoholic hydroxyl content of at least 0.2 eq./100 g; (2) A non-acidic polyester of a polycarboxylic acid crosslinking agent having more than one β-hydroxyl ester group per molecule, and at least one of components (1) and (2) having an alcoholic hydroxyl functionality of more than 2, and (II) A transesterification-promoting metal salt or complex curing catalyst which is soluble in liquid hydrocarbons. For aqueous compositions, component (I) (1) is preferably a neutralized epoxy resin/amine adduct and component (II) should be insoluble in water; they can be used for cathodic electrodeposition.
