Abstract
Abstract Thermosetting binder 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
An aqueous paint composition suitable for cathodic electrodeposition comprising a binder comprising (1) a non-acidic resinous compound having the formula: A--B--C--B).sub.m A wherein m is a number from 0 to 2, A is a group which is linked to B through a tertiary amino function and being derived from an amine having one secondary amino group, B is a group ##STR7## wherein n is a number from 0 to 4, R is a hydrocarbon radical of a dihydric phenol, and C is a group which is linked to B through two tertiary amino functions and being derived from an amine containing at least two secondary amino groups or a primary mono-amino groups, (2) a non-acidic polyester prepared by reacting a polycarboxylic acid or anhydride thereof with at least one hydroxyl-containing compound selected from the groups consisting of glycols, glycol mono-ethers and polyols, and (3) a polyvalent metal compound, said binder having from about 20% to about 100% of the amino groups neutralized with a carboxylic acid.
