ABSTRACT:
A coating composition for use as an overcoat or heat resistant coating having improved heat resistance comprised of an aqueous latex polymer emulsion and a water soluble or water-dispersible resin which containing a sufficient number of either (a) carboxyl groups or (b) carboxyl and amide groups which will form at least one anhydride ring or imide, in the presence of sufficient heat, and release water molecules, with the latex polymer having a particle size of less than about 1600 Angstroms and containing an effective amount of a nitrogen containing volatile base to achieve a pH of greater than about 7.5 to keep the resin solubilized or dispersed.
