Stabilized coating compositions

Claim 1

A LIQUID COATING COMPOSITION, CHARACTERIZED BY IMPROVED PACKAGE STABILITY AND POT LIFE, COMPRISING AN ORGANIC FILM-FORMING MATERIAL CONSISTING ESSENTIALLY OF (A) A CARBOXYLIC INTERPOLYMER MADE UP OF UNITS FROM A PLURALITY OF COPOLYMERIZABLE ALPHA MONOETHYLENICALLYUNSATURATED MONOMERS INCLUDING CARBOXYLIC UNITS FROM AN ALPHA, BETA MONOETHYLENICALLY-UNSATURATED CARBOXYLIC MONOMER HAVING FROM ONE TO TWO CAROXYL MOIETIES PER MOLECULE IN A PROPORTION SUFFICIENT TO PROVIDE THE RESULTING CARBOXYLIC INTERPOLYMER WITH FROM 1 TO 25 MOL PERCENT OF THE CARBOXYL MOIETY, AND (B) A FILM-FORMING EPOXY COMPOUND COMPATIBLE THEREWITH HAVING AT LEAST ONE OXIRANE MOIETY PER MOLECULE, CHARACTERIZED BY AN OXIRANE OXYGEN ATOM LINKED TO TWO ADJACENT CARBON ATOMS, ANY FUNCTIONAL MOIETIES IN ADDITION TO SAID 1,2-OXIRANE MOIETY IN SAID EPOOXY COMPOUND REACTIVE WITH CARBOXYL MOIETIES OF SAID CARBOXYLIC INTERPOLYMER BEING LIMITED TO HYDROXYL MOIETIES, A QUATERNARY AMMONIUM CATALYST, AND AN ALIPHATIC POLYAMINE POLYACETIC ACID STABILIZER CHARACTERIZED AS HAVING A PLURALITY OF TERTIARY AMINE NITROGEN ATOMS INCLUDING TWO TERMINAL TERTIARY AMINE NITROGEN ATOMS, EACH TERITARY NITROGEN ATOM BEING LINKED TO AN ADJACENT NITROGEN ATOM THROUGH A LINKING DIVALENT SATURATED HYDROCARBON RADICAL OF TWO TO SIX CARBON ATOMS, SAID LINKING HYDROCARBON RADICAL HAVING NO MORE THAN TWO CARBON ATOMS, WHEN SAID PLURALITY OF TERTIARY NITROGEN ATOMS EXCEEDS TWO, THE VALENCES OF SAID TERTIARY AMINE NITROGEN ATOMS IN EXCESS OF THOSE SATISFIED BY LINKING DIVALENT HYDROCARBON RADICAL BEING SATISFIED WITH AT LEAST THREE -CH2-COOH MOIETIES AND NO MORE THAN TWO -CH2-CH2-OH MOIETIES, SAID FILM-FORMING MATERIAL BEING IN SOLUTION IN A VOLATILE LIQUID INERT ORGANIC SOLVENT THEREFOR.
