Abstract
Abstract The present invention is directed to polyglycidyl ethers having, on average, n epoxy groups per molecule, where 1<n≦2, which comprise the reaction products of multifunctional polyglycidyl ethers having, on average, x epoxy groups per molecule, where x>2, with (x-n) mol of monofunctional phenols per mol of the multifunctional polyglycidyl ether and to a process for their preparation and their use in preparing thermosetting coating compositions, particularly for use in electrodeposition coating of articles.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A process for the preparation of a thermosetting resin coating composition suitable for electrodeposition which comprises (A) reacting (1) a polyglycidyl ether having, on average, n epoxy groups per molecule, where 1<n≦2, prepared by reacting a multifunctional glycidyl novolac resin having, on average, x epoxy groups per molecule, where x>2, with (x-n) moles of a monofunctional alkyl-substituted phenol at a temperature of from about 120° to about 180° C. in the presence of an acid or base catalyst, with (2) an amino compound containing, on average, two amino-hydrogens per molecule or an alkali metal salt of an amino acid in aqueous medium at a temperature from about 100° to about 120° C., and then (B) combining the resultant resinous compounds wih a water soluble cross-linking compound in a weight ratio of from bout 95:5 to about 65:35, before or after neutralization.
Claim 2
Dependent Claim
