AN ACYLATION PROCESS COMPRISING REACTING (A) A CARBOXYLATED PHENOL-ALDEHYDE RESIN, AND (B) AN AMINEMODIFIED PHENOL-ALDEHYDE RESIN IN A MOLAR RATIO OF CARBOXYLATED RESIN TO AMINE-MODIFIED RESIN OF 1 TO 6:1, SAID CARBOXYLATED RESIN (A) BEING A FUSIBLE, CARBOXYLCONTAINING, XYLENE-SOLUBLE, WATER-INSOLUBLE, LOW-STAGE PHENOL-ALDEHYDE RESIN; SAID RESIN BEING DERIVED BY REACTION BETWEEN A MIXTURE OF A DIFUNCTIONAL MONOHYDRIC HYDROCARBON-SUBSTITUTED PHENOL AND SALICYLIC ACID ON THE ONE HAND, AND AN ALDEHYDE HAVING NOT OVER 8 CARBON ATOMS AND HAVING ONE FUNCTIONAL GROUP REACTIVE TOWARD BOTH COMPONENTS OF THE MIXTURE ON THE OTHER HAND; THE AMOUNT OF SALICYLIC ACID EMPLOYED IN RELATION TO THE NON-CARBOXYLATED PHENOL BEING SUFFICIENT TO CONTRIBUTE AT LEAST SALICYLIC ACID RADICAL PER RESIN MOLECULE AND THE AMOUNT OF DIFUNCTIONAL MONOHYDRIC HYDROCARBON-SUBSTITUTED PHENOL BEING SUFFICIENT TO CONTRIBUTE AT LEAST ONE DIFUNCTIONAL MONOHYDRIC HYDROCARBON-SUBSTITUTED PHENOL RADICAL PER MOLECULE; SAID RESIN BEING FORMED IN THE SUBSTANTIAL ABSENCE OF PHENOLS OF FUNCTIONALITY GREATER THAN TWO, AND SAID PHENOL BEING OF THE FORMULA
