Claim 1

AN ESTERIFACTION PRODUCT OF (1) AN OXYALKYLATED C4- TO C18-HYDROCARBON-SUBSTITUTED DIFUNCTIONAL MONOCYCLIC MONOHYDRIC PHENOL-C1TO C8-ALDEHYDE RESIN IN WHICH THE C4-TO C18SUBSTITUTENT IS IN ONE OF THE POSITIONS, ORTHO AND PARA OF THE PHENOL AND IN WHICH THE ALDEHYDE IS ONE WHICH HAS BUT ONE FUNCTIONAL GROUP REACTIVE WITH SAID PHENOL IN WHICH THE RATIO OF OXYALKYLENE GROUPS TO PHENOLIC NUCLEI IS FROM LESS THAN 2:1 TO ABOUT 0.5:1, AND THE ALKYLENE RADICALS OF THE OXYALKYLENE GROUPS ARE THOSE OF ALPHA, BETA-ALKYLENE OXIDES AND ARE SELECTED FROM THE CLASS CONSISTING OF ETHYLENE, PROPYLENE, BUTYLENE, HYDROXYPROPYLENE AND HYDROXYBUTYLENE RADICALS, AND THE OXYALKYLENE GROUPS ARE LINKED TO THE PHENOLIC NUCLEI AT THE 1-POSITION, AND (2) THE FATTY, ACIDS OF AN OIL OF THE CLASS CONSISTING OF DRYING AND SEMI-DRYING OILS IN AMOUNT AT LEAST 20% BASED STOICHIOMETRICALLY ON THE TOTAL HYDROXYL CONTENT OF THE OXYALKYLATED RESIN; WITH THE PROVISO THAT AT LEAST 50% STOICHIOMETRICALLY OF THE TOTAL HYDROXYL CONTENT OF THE OXYALKYLATED RESIN IS ESTERIFED BY A MATERIAL OF THE CLASS CONSISTING OF SUCH FATTY ACIDS AND POLCARBOXY ACID CONTAINS THE PROVISO THAT THE POLYCARBOXY ACID CONTAINS ONLY OXYGEN, HYDROGEN AND CARBON AND IN AMOUNT DOES NOT EXCEED 70% BASED STOICHIOMETHRICALLY ON THE TOTAL HYDROXYL CONTENT OF THE OXYALKYLATED RESIN.
