Heat sensitive substrates coated with waterborne coating compositions

A coated substrate comprising:

• A) a heat sensitive substrate having a heat distortion temperature less than 120 degrees C., and
• B) a coating layer deposited on at least one surface of the substrate, wherein the coating layer is deposited from a waterborne coating composition comprising:
• (a) a continuous phase comprising water, and
• (b) a dispersed phase comprising:
• (i) pigments;
• (ii) polymeric particles prepared from the polymerization of a mixture of ethylenically unsaturated compounds including ethylenically unsaturated monomers comprising from:
• (A) 2 to 30 percent by weight of a multi-ethylenically unsaturated monomer and
• (B) at least 30 percent by weight of an aldo or keto group-containing ethylenically unsaturated monomer, the percentages by weight being based on total weight of the ethylenically unsaturated monomers;
• and
• (iii) a polyhydrazide.
