PROCESS FOR THE PREPARATION OF WATER-DILUTABLE RESINS, RESINS PRODUCED THEREBY, AND THEIR USE IN THERMOSETTING SURFACE COATINGS

Resinous compounds, for aqueous thermosetting coating dispersions or solutions ether neutralization, are prepared by reacting a diglycidyl ether of a dihydric phenol with a mono-carboxylic acid and dimerized unsaturated fatty acids, with epoxy equal to or in slight excess over carboxyl, below 150.de...

Zusammenfassung:	Resinous compounds, for aqueous thermosetting coating dispersions or solutions ether neutralization, are prepared by reacting a diglycidyl ether of a dihydric phenol with a mono-carboxylic acid and dimerized unsaturated fatty acids, with epoxy equal to or in slight excess over carboxyl, below 150.degree.C in the presence Or an epoxy/carboxyl esterification catalyst to produce a non-acidic intermediate, and reacting the intermediate below 150.degree.C with a polycarboxylic acid anhydride in amounts to provide an acid value from 5-35; aqueous dispersions are prepared by at least 50% neutralization of compounds having acid value 5-15.
