Abstract
Disclosed are substrates at least partially coated with a multi-layer composite coating system comprising a treatment layer deposited from a composition comprising a radiation cure initiator, wherein the composition is substantially free of any radiation-curable materials. The present invention is also directed to methods for improving the adhesion of multi-layer coating system to substrates, particularly porous substrates; such as wood.
Claims20
A substrate at least partially coated with a multi-layer composite coating system comprising:
- (a) a treatment layer deposited from a composition comprising a radiation cure initiator and a diluent, wherein the composition is substantially free of radiation curable material,
- (b) a colorant layer deposited from a composition comprising a film-forming resin, a colorant, and a diluent, and
- (c) at least one of a sealer and topcoat deposited from a radiation curable composition, wherein the sealer and/or topcoat is applied over at least a portion of the colorant layer and the treatment layer.
A method for improving the adhesion of a multi-layer composite coating system to a porous substrate, wherein the coating system comprises (i) a colorant layer deposited onto the substrate from a composition comprising a film-forming resin, a colorant, and a diluent, and (ii);
- at least one of a sealer and topcoat deposited from a radiation curable composition, wherein the sealer and/or topcoat is applied over at least a portion of the colorant layer, the method comprising:
- depositing a treatment layer from a composition comprising a radiation cure initiator to the substrate prior to depositing the sealer and/or topcoat onto the substrate, wherein the composition from which the treatment layer is deposited is substantially free of radiation curable material.
