Abstract
Abstract The invention concerns compositions for producing adherent polymeric coatings on a variety of substrates. The coating compositions comprise polymeric latices of colloidal polymer particles of at least one polymer capable of being deposited in the form of a film. In addition to the film-forming polymer, the coating composition comprises a discrete latex component which is a precursor of a material aiding rapid film formation through inter-reaction with the polymer particles, and may also have an affinity toward the substrate so as to function as a linking agent. This material can cause film formation by disrupting the colloidal stability of the polymer particles. It is possible to select as the discrete latex component a precursor of a material which has the dual function of increasing speed of film formation while fostering the adherence and bonding of the film to the substrate because of the material's relative affinities for the polymer and for the substrate.
