Abstract
A printed substrate, wherein a printed polymer layer is present on a surface of the substrate, is disclosed. The printed polymer layer comprises a polymer chosen from one or more of polyvinyl chloride, a copolymer of vinyl chloride and vinyl acetate, and a terpolymer of vinyl chloride, vinyl acetate and ethylene; a plasticizer; a colorant; and calcium carbonate.
Claims19
A printed substrate, wherein a printed polymer layer is present on a surface of the substrate;
- wherein the printed polymer layer comprises:
- (a) a polymer chosen from one or more of polyvinyl chloride, a copolymer of vinyl chloride and vinyl acetate, and a terpolymer of vinyl chloride, vinyl acetate and ethylene;
- (b) a plasticizer;
- (c) a colorant;
- and
- (d) calcium carbonate;
- wherein the weight ratio of calcium carbonate to polymer in the printed polymer layer is in the range of 0.1 to 3.5.

A method for printing onto a substrate, comprising steps of
- applying a dispersion of polymer particles in a liquid plasticizer to a substrate to form a polymer layer, wherein the polymer is chosen from one or more of polyvinyl chloride, a copolymer of vinyl chloride and vinyl acetate, and a terpolymer of vinyl chloride, vinyl acetate and ethylene;
- printing an ink onto the polymer layer to form a printed polymer layer, wherein the ink comprises a colorant and thereby the printed polymer layer comprises the colorant;
- and
- curing the printed polymer layer to change the printed polymer layer from liquid to solid;
- wherein the dispersion of polymer particles in a liquid plasticizer comprises calcium carbonate, such that the weight ratio of calcium carbonate to polymer is in the range of 0.1 to 3.5.
