ABSTRACT:
This invention relates to coating compositions which are "solid" prior to application, yet, which when applied to a substrate, flow and level in a manner similar to conventional coating compositions. The coating compositions of the invention comprise a gelled coating composition, capable of application and flow on a solid substrate comprising: (a) a water reducible polymer, (b) water, (c) an electrolyte, (d) a colloidal gelling agent, gelable by interaction with the electrolyte, in an amount sufficient, when interacted with said electrolyte, to gel the composition to form a stable semisolid and to provide a composition reducible to a coating application viscosity upon the application of a relatively small shearing force at a relatively small shearing rate; which gelled coating composition, after being sheared to a coating application viscosity, does not recover substantial colloidal gelling agent contributed gel structure and (e) an amount of a gel structure formation rate increasing compound which corresponds, or is hydrolyzable in situ to effectively provide a compound which corresponds to the formula:
