Resins having substantial oil lengths and improved water solubility prepared from polycondensation reaction products

Claim 1

A RESIN HAVING WATER SOLUBILITY AND BEING SUITABLE FOR THE FORMATION OF AN AIR-DRY SURFACE COATING FILM WHICH RESIN COMPRISES A REACTION PRODUCT OF (I) A POLYCONDENSATION REACTION PRODUCT OF (A) AN ACIDIC MEMBER BEING SELECTED FROM AT LEAST ONE MEMBER OF THE CLASS CONSISTING OF TRIMELLITIC ACID, TRIMELLITIC ANHYDRIDE, HEMIMELLITIC ACID, HEMIMELLITIC ANHYDRIDE, TRIMESIC ACID (B) AN ETHER CONTAINING MONOHYDRIC ALCOHOL SELECTED FROM AT LEAST ONE MEMBER OF THE CLASS CONSISTING OF MONOHYDROXYALKYLENE TETRAHYDROFURAN HAVING FROM 1 TO ABOUT 4 CARBON ATOMS IN SAID ALKYLENE GROUP AND POLYALKYLENE GLYCOL MONOALKYL ETHER HAVING FROM 2 TO 8 ETHER GROUPS, FROM 2 TO 3 CARBON ATOMS IN EACH ALKYLENE GROUP, AND FROM 1 TO 8 CARBON ATOMS IN SAID ALKYL GROUP, AND (C) A DIHYDROXYL GROUP AFFORDING MATERIAL DERIVED FROM A COMPOUND AFFORDING 3-4 HYDROXYL GROUPS, AN UNSATURATED FATTY ACID AND A FURAN SUBSTITUTED ALIPHATIC ACID HAVING FROM 1 TO ABOUT 3 CARBON ATOMS IN SAID ALIPHATIC ACID GROUP, SAID MONOHYDRIC ALCOHOL BEING PRESENT IN A MOLE RATIO TO SAID ACIDIC MEMBER OF AT LEAST ABOUT 0.4, SAID POLYCONDENSATION REACTION PRODUCT BEING CHARACTERIZED BY AN OIL LENGTH OF FROM ABOUT 45% TO ABOUT 80%, SAID FURAN SUBSTITUTED ACID BEING PRESENT IN AN AMOUNT SUFFICIENT TO IMPART WATER SOLUBILITY TO SAID REACTION PRODUCT, AND (II) AN ALKALINE AGENT SELECTED FROM THE CLASS CONSISTING OF AMMONIA, ALKYLAMINES, HETEROAMINES, AND ALKANOLAMINES, SAID RESIN BEING CHARACTERIZED BY BEING WATER SOLUBLE.
