Abstract:
An improved process for applying at least one ink-receiving layer to a non-permeable substrate, said process comprising:(a) applying a porous basecoat to a surface of said non-permeable substrate, said porous basecoat comprising a plurality of pores; (b) applying a topcoat on said porous basecoat, the improvement comprising (1) directly forming said basecoat on said substrate surface; (2) drying said basecoat, followed by applying a re-wet liquid directly to said porous basecoat to form a wetted basecoat, prior to applying said topcoat thereon, to thereby saturate said pores sufficient to prevent any air bubbles from forming in said topcoat; and (3) directly forming said topcoat on said wetted basecoat followed by drying said topcoat, to form said topcoat so as to be substantially free of irregularities or defects wherein said improved process produces a substantially uniform and bubble-free topcoat and is performed without cast-coating or lamination.
