Abstract
Abstract A floor or wall covering is disclosed which comprises a foamed polymeric layer including raised areas separated by recessed areas and a protective layer over the upper surface of the covering and comprising a first non-foamed layer and a second non-foamed layer and in which the second non-foamed layer is discontinuous and leaves part at least of the first non-foamed layer uncovered and has a gloss different from that of the first non-foamed layer or at least one of the first and second non-foamed layers is discontinuous and provides the protective layer with a difference in thickness that imparts a pattern in relief to the said covering.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
131 words
A floor or wall covering comprising a foamed polymeric layer including raised areas separated by recessed areas and a protective layer over the upper surface of the covering and comprising a first non-foamed layer and a visible second non-foamed layer above the first layer and in which the second non-foamed layer is discontinuous and leaves part at least of the first non-foamed layer uncovered and has a gloss different from that of the first non-foamed layer, and in which the thickness of the first and second non-foamable layers together is not more than 0.1 mm more than the thickness of the thicker of the non-foamable layers, and the thickness of the raised areas of the foamed polymeric layer is more than 0.1 mm more than the thickness of the recessed areas.
Claim 2
Dependent Claim
131 words
A floor or wall covering comprising a foamed polymeric layer including raised areas separated by recessed areas and a protective layer over the upper surface of the covering and comprising a first non-foamed layer and a visible second non-foamed layer above the first layer and in which the second non-foamed layer is discontinuous and leaves part at least of the first non-foamed layer uncovered and has a gloss different from that of the first non-foamed layer, and in which the thickness of the first and second non-foamable layers together is not more than 0.1 mm more than the thickness of the thicker of the non-foamable layers, and the thickness of the raised areas of the foamed polymeric layer is more than 0.1 mm more than the thickness of the recessed areas.
Claim 3
Dependent Claim
19 words
A covering according to claim 1 in which the second non-foamed layer at least partially overlies the first layer.
Claim 4
Dependent Claim
17 words
A covering according to claim 2, in which the second layer is less than 0.1 mm thick.
Claim 5
Dependent Claim
25 words
A covering according to claim 1 in which the raised areas of the foamed layer are in register with the pattern of differences in gloss.
Claim 6
Dependent Claim
23 words

Claim 10
Dependent Claim
30 words
A covering according to claim 1 wherein the thickness of the non-foamed layers together is 0.05 to 0.1 mm more than the thickness of the thicker of the non-foamed layers.
