Abstract

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 77 words
A decorative surface covering product comprising: (a) a substrate; (b) a layer of fused colored stencil vinyl fines forming a granular material substantially covering said substrate and bonded thereto; and (c) a layer of discrete inverted substantially transparent raised elements of a cured thixotropic plastic material extending completely into the layer of granular material, whereby the colored fines are clearly visible in the areas between the raised elements and appear as blurred colors through the raised elements.
Claim 2
Dependent Claim 77 words
A decorative surface covering product comprising: (a) a substrate; (b) a layer of fused colored stencil vinyl fines forming a granular material substantially covering said substrate and bonded thereto; and (c) a layer of discrete inverted substantially transparent raised elements of a cured thixotropic plastic material extending completely into the layer of granular material, whereby the colored fines are clearly visible in the areas between the raised elements and appear as blurred colors through the raised elements.
Claim 3
Dependent Claim 63 words
A decorative surface covering product of claim 1 wherein the decorative surface of the granular material, opposite to the surface thereof bonded to the substrate, has the inverted raised elements extending thereinto so that the raised elements are visable on the decorative surface of the granular material whereby the raised elements form a gerometric design on the decorative surface of the granular elements.
Claim 4
Dependent Claim 18 words
A decorative surface covering product of claim 2 wherein the granular material appears as particles of different colors.
Claim 5
Dependent Claim 108 words
A decorative surface covering of claim 3 wherein the discrete raised elements are at least transparent or translucent and arranged in a geometric pattern design, and when positioned within the colored granular layer of different color particles, but visable on the decorative surface thereof, the pattern design of the discrete elements provides the decorative surface of the granular layer with a discrete geometric pattern, with the discrete elements surrounded by colored particles clearly visable in the area between the discrete elements, and in the area below the discrete elements the colored particles appear in a blurred colored particle pattern partially visable through the transparent or translucent discrete elements.
