Water solubilized epoxy resin esters of fumaric- or itaconic-fatty acid adducts

Claim 1

A PROCESS FOR THE PREPARATION OF WATER SOLUBLE EPOXY ESTERS WHICH COMPRISES (I) AT A TEMPERATURE ABOVE 390*F. HEATING AND CONDENSING (A) AN UNSATURATED FATTY ACID HAVING 10 TO 24 CARBON ATOMS IN ITS HYDROCARBON CHAIN WITH (B) 5 TO 25 PERCENT BY WEIGHT BASED ON THE UNSATURATED FATTY ACID OF FUMARIC ACID TO FORM A CONDENSATE-FATTY ACID MIXTURE HAVING AN ACID VALUE IN THE RANGE OF 165 TO 305 (II) SUBSEQUENTLY AT A TEMPERATURE BELOW 390*F. WHICH SUPPRESSES CARBOXY-HYDROXY REACTIONS, REACTING THE CONDENSATE-FATTY ACID MIXTURE WITH SUFFICIENT GLYCIDYL POLYETHER OF A DIHYDRIC PHENOL OR ALIPHATIC POLYOL, HAVING AN EXOPIDE EQUIVALENT BELOW 100, TO REDUCE THE ACID VALUE TO ONE-HALF TO ONE-THIRD OF ITS INITIAL VALUE, FORMING AN EPOXY ESTER COMPOSITION, THE ACID VALUE INDICATING THE PRESENCE OF CARBOXY GROUPS IN THE COMPOSITION. (III) AND THEN REACTING THE EPOXY ESTER COMPOSITION WITH SUFFICIENT AMINO COMPOUND SELECTED FROM THE GROUP CONSISTING OF AMMONIA AND WATER SOLUBLE AMINES TO FORM A WATER SOLUBE AMINE SALT OF THE EPOXY ESTER COMPOSITION.
