WATERBORNE COATING COMPOSITIONS AND HEAT SENSITIVE SUBSTRATES COATED THEREWITH |
摘要 |
The present invention is directed to a coated substrate comprising:
A) a heat sensitive substrate having a heat distortion temperature less than 120 degrees C., andB) 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) optional pigments;(ii) polymeric particles containing carboxylic acid functionality prepared from the polymerization of a mixture of ethylenically unsaturated compounds including ethylenically unsaturated monomers; and(iii) a polycarbodiimide or a polyhydrazide. The present invention is further directed to the waterborne coating compositions used to prepare the coated substrates. |

1. 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. |
