Abstract
A method of manufacture for producing a decorative laminate which exhibits through-color printing is provided in which a layer of absorptive PVC resin particles of substantially only one particle thickness is printed with, for example, three differently colored vinyl plastisol printing inks. The decorative article is useful as a floor covering.
Claims10
A method for making a decorative laminate suitable as a floor covering, said method comprising:
- applying to a substrate material a vinyl plastisol composition;
- applying an excess of absorptive PVC resin particles of type GP PVC resin having a particle size diameter between about 6 mils and about 20 mils, a cell classification number of 4 and a plasticizer absorption greater than about 40 grams per 100 grams of PVC resin over said vinyl plastisol composition and the surface of said substrate and removing the excess of said absorptive PVC resin particles that do not adhere to said vinyl plastisol composition;
- heating said substrate to gel said vinyl plastisol composition thereon and thereby firmly adhere said absorptive PVC resin particles thereto;
- applying at least one PVC plastisol printing ink composition to said absorptive PVC resin particles, and heating said substrate to gel said PVC plastisol printing ink composition and provide a layer of printed, absorptive PVC resin particles;
- and
- forming a top resinous layer on said layer of printed absorptive PVC resin particles by applying a transparent synthetic organic polymer over said printed, absorptive PVC resin particles, followed by heating the resulting intermediate laminate of resinous layers thereby to provide a fused decorative laminate,
- whereby the printed regions of said decorative laminate exhibit through-color printing.

A method for making a decorative laminate suitable as a floor covering, said method comprising:
- forming a gelled, foamable, resinous vinyl layer on a substrate material by applying a foamable vinyl plastisol onto said substrate and heating said resinous layer thereby to provide said gelled, foamable, resinous layer;
- applying to said gelled, foamable, resinous vinyl layer a vinyl plastisol adhesive composition;
- applying an excess of absorptive PVC resin particles of type GP PVC resin having a particle size diameter between about 6 mils and about 20 mils, a cell classification number of 4 and a plasticizer absorption greater than about 40 grams per 100 grams of PVC resin over said vinyl plastisol adhesive composition and removing the excess of said absorptive PVC resin particles that do not adhere to said vinyl plastisol adhesive composition;
- heating said substrate to gel said vinyl plastisol adhesive composition and thereby firmly adhere said absorptive PVC resin particles to said vinyl plastisol adhesive composition;
- applying at least one PVC plastisol printing ink composition to said absorptive PVC resin particles, and heating said substrate to gel said PVC plastisol printing ink composition and provide a layer of printed, absorptive PVC resin particles;
- forming a top resinous layer on said printed, absorptive PVC resin particles by applying a transparent synthetic organic polymer over said printed, absorptive PVC resin particles;
- and
- heating the resulting intermediate laminate of resinous layers thereby to provide a fused decorative laminate,
- whereby the printed regions of said decorative laminate exhibit through-color printing.
