Coating composition, substrate, method for coating a porous substrate, and method for improving adhesion of a coating system to a porous substrate

摘要

coating composition, substrate, porous substrate, method for depositing on a porous substrate a multilayer composite coating and method for improving adhesion of a multilayer composite coating system to a porous substrate. Coating compositions are disclosed which include a film-forming resin, an irradiation curing initiator, a dye, and a diluent. These compositions are substantially free of irradiation curable material. Also disclosed are substrates at least partially coated with such compositions, substrates at least partially coated with a multilayer composite coating comprising at least one coating layer deposited from such compositions, and methods for improving the adhesion of a multilayer composite coating system to such compositions. a porous substrate.
