Abstract

The invention provides decorative, inlaid sheet materials which incorporate a matrix layer of discrete, low aspect ratio particles embedded in a resinous coating. The use of printed patterns which are visible beneath the adhesive matrix containing the particles constitutes a characteristic of the invention. The sheet materials of this invention are real through-patterned inlaids which do not lose their pattern due to wear in use, and which offer unique design advantages and flexibility, as well as superior properties.

Claims

1. A decorative, inlaid floor or wall covering which comprises:

a) a substrate,

b) a printed layer applied over said substrate in the form of a pattern, and

c) an adhesive matrix layer overlaying said printed layer and consisting essentially of an adhesive in which are embedded spherical or spheroidal particles having an aspect ratio no greater than about 2;

1 and which are a blend of pigmented and transparent particles, wherein a dense loading of said particles is provided to prevent the underlying pattern from showing through interstices between said particles,

wherein said pattern is visible through said adhesive matrix layer.

2. The product of claim 1 wherein the substrate is a flexible mat or a non-asbestos felt sheet.

3. The product of claim 2 wherein the printed layer is a gelled or foamed resinous layer, the surface of which has been printed with an ink.

4. The product of claim 3 wherein the adhesive matrix layer contains as a major component a homopolymer or copolymer of vinyl chloride.

5. The product of claim 4 wherein said particles are plasticized polyvinyl chloride particles having an aspect ratio no greater than about 1.5:

1.

6. The product of claim 1 further including a latex layer overlaying the substrate.

7. The product of claim 1 wherein the spherical or spheroidal particles are resinous particles and are a blend of pigmented and transparent particles.

8. The product of claim 7 wherein said pigmented particles are selected from the group consisting of translucent and opaque particles.

9. The product of claim 8 wherein said resinous particles are spheroidal, plasticized polyvinyl chloride particles having an aspect ratio no greater than about 1.5:

1.

20. The product of claim 8 wherein particle density is from about 0.4 to about 0.8 pounds per square yard.

10. A decorative, inlaid floor or wall covering which comprises:

a) a flexible mat substrate,

b) a gelled or foamed, resinous layer overlaying said substrate, the surface of which is printed in the form of a pattern with one or more inks, and

c) an adhesive matrix layer overlaying said printed layer, containing a homopolymer or a copolymer of vinyl chloride, and consisting essentially of an adhesive in which are embedded spherical or spheroidal resinous particles having an aspect ratio no greater than bout 2;

1 and which are a blend of i) pigmented particles which are selected from the group consisting of translucent and opaque particles, and ii) transparent particles, wherein a dense loading of said particles is provided to prevent the underlying pattern from showing through interstices between said particles,

wherein said pattern is visible through said adhesive matrix layer.

11. The product of claim 10 wherein said particles are plasticized polyvinyl chloride particles.

12. The product of claim 10 wherein the resinous layer is a gelled, foamed or foamable layer and at least one of the inks is a suppressant ink.

13. The product of claim 10 wherein the particles are discrete, spherical or spheroidal vinyl chloride, homopolymer or copolymer polymerization agglomerates, sized between about 0.004-0.040 inches.

14. The product of claim 10 further including a latex layer disposed between the substrate and the resinous layer.

15. The product of claim 10 wherein the adhesive matrix layer is coated with at least one wearlayer.

21. The product of claim 13 wherein particle density is from about 0.4 to about 0.8 pounds per square yard.

16. In a decorative, inlaid floor or wall covering comprising a substrate and a printed layer applied over said substrate in the form of a pattern, the improvement which comprises an adhesive matrix layer applied over said printed layer which consists essentially of spherical or spheroidal resinous particles having an aspect ratio no greater than about 2:

1 embedded in an adhesive, wherein a dense loading of said particles is provided to prevent the underlying pattern from showing through interstices between said particles, and wherein said pattern is visible through said adhesive matrix layer.

17. The product of claim 16 further comprising at least one wearlayer applied over said adhesive matrix layer.

18. A decorative, inlaid floor covering which comprises:

a) a substrate,

b) a foamed layer overlaying the substrate, the surface of which is printed in the form of a pattern, and

c) an adhesive matrix layer overlaying the printed foamed layer and consisting essentially of an adhesive in which are embedded spherical or spheroidal resinous particles having an aspect ratio no greater than about 2;

1 and which are a blend of i) pigmented particles which are selected from the group consisting of translucent and opaque particles, and ii) transparent particles, wherein a dense loading of said particles is provided to prevent the underlying pattern from showing through interstices between said particles,

wherein said pattern is visible through said adhesive matrix layer.

19. The product of claim 18 further comprising at least one wearlayer applied over said adhesive matrix layer.

22. The product of claim 19 wherein particle density is from about 0.4 to about 0.8 pounds per square yard.
