Abstract

Abstract WHEREIN R9 IS A DIIVALENT AROMATIC HYDROCARBN CONSISTING OF POLYISCOYANATE OF THEFORMULA O=C=N-R9-N(-CO-NH-R9-N=C=O)2 WHEREIN R9 IS A DIVALENT AROMATIC HYDROCARBON RADICAL HAVING 1-12 CARBON ATOMS AND METHYLENE BIS(4-CYCLOHEXYL ISOCYANATE) AND AN AROMATIC SOLVENT FOR THE POLYISOCYANATE THAT IS COMPATIBLE WITH THE COATING COMPOSITION. O=C=N-(R9)-N(-CO-NH-(R9)-N=C=O)2 WHEREIN R1 IS A HYDROCARBON GROUP HAVING 2-20 CARBON ATOMS; R2 IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND AN ALKYL GROUP HAVING 1-4 CARBON ATOMS; R3 AND R4 ARE R8-COO-CH2-; R5 IS AN ALIPHATIC HYDROCARBON GROUP HAVING 1-6 CARBON ATOMS; R6 AND R7 ARE INDIVIDUALLY SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, A SATURATED ALIPHATIC HYDROCARBON GROUP HAVING 1-6 CARBON ATOMS; AND R8 IS FROM DRYING OIL FATTY ACIDS, AND CORRESPONDINGLY (2) 5-60% BY WEIGHT OF AN ALKYD RESIIN OR A BLEND OF ALKYD RESNS; WHEREIN THE ALKYD RESIN IIS THE ESTERFICATION PRODUCT OF DRYIING OIL FATTY ACIDS, A POLYHYDRIC ALCOHOL AND AN AROMATIC DICARBOXYLIC ACID OR AN ANHYCARBOXYLIC ACID AND AN ANHYDRIDE OF AN AROMATIC DICARBOXYLIC ACIID; AND UTILIIZED WIITH SAID COATING COMPOSITION ABOUT 0.5-200% BY WEIGHT, BASED ON THE WEIGHT OF THE COATIING COMPOSITION, OF A OLYISOCYANATE SOLU- -COO-R5-N(-R6)-R7 AND HAVING ATTACHED TO THE POLYMER BACKBONE 0.515% BY WEIGHT, BASED ON THE WEIGHT OF THE POLYMER, OF PENDENT AMINO ESTER GROUPS OF THE FORMULA -(C(-R1)(-C<(=N-C(-R3)(-R4)-CH2-O-))-CH(-R2))- 1. A COATING COMPOSITION COMPRISJNG 5-60% BY WEIGHT OF A POLYMER BLEND AND 95-40% BY WEIGHT OF A SOLVENT FOR THE POLYMER BLEND IN WHICH THE BLEND CONSISTS ESSENTIALLY OF (1) 40-95% BY WEIGHT OF AN ACRYLIC VINYL OXAZOLINE ESTER POLYMER THAT HAS A RELATIVE VISCOSITY OF ABOUT 1.03-1.30 MEASURED ACCODING TO ASTM-D-445-64T, METHOD B AT 25*C. AND WHICH CONSISTS ESSENTIALLY OF A BACKBONE OF 50-96.5% BY WEIGHT, BASED ON THE WEIGHT OF THE POLYMER, OF POLYMERIZED ETHYLENICALLY UNSATURATED MONOMERS SELECTED FROM THE GROUP CONSISTING OF AN ALKYL METHACRYLATE HAVING 1-8 CARBON ATOMS IN THE ALKYL GROUP, CYCLOHEXYL METHACRYLATE, ACRYLONITRILE, STYRENE AND MIXTURES OF THESE MONOMERS AND UP TO 20% BY WEIGHT, BASED ON THE WEIGHT OF THE POLYMER, OF A HYDROXY CONTAINING MONOMER SELECTED FROM THE GROUP CONSISTING OF HYDROXY ALKYL ACRYLATE AND HYDROXY ALKYL METHACRYLATE HAVING 2-4 IN THE ALKYL GROUPS AND CONTAINING IN THE BACKBONE 3-35% BY WEIHT, BASED ON THE WEIGHT OF THE POLYMER, OF POLYMERIZED VINYL OXAZOLIINE ESTERS OF THE FORMULA
