Abstract
Abstract Acidic resins which, after being neutralized, are used in watersoluble paints and comprising the reaction product of (I) a compound having at least one oxirane ring and a mean molecular weight of 100 to 20,000, (II) at least one polyunsaturated monocarboxylic acid having 8 - 20 carbon atoms and (III) an Alpha , Beta -unsaturated monocarboxylic acid of the formula: WHEREIN X, Y and Z are independently selected from the group consisting of hydrogen, alkyl and aryl. This reaction product may also optionally include a phenolic compound (IV), in which case an Alpha , Beta -unsaturated dicarboxylic acid (or anhydride) (V) of the formula: WHEREIN S and T are independently selected from the group consisting of hydrogen, alkyl and aryl, may be substituted for component (III).
