Abstract
Abstract COATING COMPOSITIONS CHARACTERIZED IN THAT THEY ARE WATER-SOLUBLE UPON NEUTRALIZATION COMPRISING (A) CARBOXY GROUP CONTAINING REACTION PRODUCTS OF ALPHA-BETA ETHYLENICALLY UNSATURATED CARBOXYLIC ACIDS AND/OR DICARBOXYLIC ACIDS AND/OR ANHYDRIDES AND/OR SEMI-ESTERS AND/ OR SEMI-AMIDES WITH DIENE POLYMERS AND UNMODIFIED AND/ OR MODIFIED UNSATURATED FATTY ACIDS WITH MORE THAN 8 C ATOMS; (B) ONE OR MORE HEAT-REACTIVE CONDENSATION PRODUCTS OF FORMALDEHYDE WITH PHENOL CARBOXYLIC ACIDS, WHICH, IF DESIRED, CAN BE ETHERIFIED AND FURTHER, IF DESIRED, CONDENSATION PRODUCTS OF FORMALDEHYDE WITH PHENOLS AND/OR UREAS AND/OR AMINOTRIAZINES CAN BE CO-EMPLOYED; AND, OPTIONALLY, (C) ONE OR MORE POLYHYDROXY COMPOUNDS WITH AT LEAST TWO HYDROXY GROUPS AND A MOLECULAR WEIGHT OF BETWEEN 50 AND 3000 ARE DESCRIBED. THE COMPOSITIONS, WHILE BEING QUICK DRYING, ARE NOT OVERLY SENSITIVE TO OXIDATION PERMITTING THOROUGH DRING OF COATINGS.
