Abstract
Abstract A technique for the manufacture of synthetic sheet material having a textured surface and suited for use as floor or wall covering. The technique in accordance with the invention includes the printing of a decoration on a support member and the applying of a transparent plastisol in the form of a discontinuous layer over and in accordance with the decoration. The invention also contemplates the application of a continuous wear layer which, in the final product, will either be disposed between the discontinuous transparent plastisol and the decoration or will cover the discontinuously applied plastisol which provides the textured effect.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
97 words
A process for the manufacture of sheet material having a relief effect on at least a first surface comprising the steps of: printing a decoration on a surface of a support member; applying at least one discontinuous layer of a transparent plastisol over and in registration with at least part of the printed decoration, the plastisol being applied in a thickness of at least ten mils and imparting a desired relief appearance to the printed decoration, the decoration being viewed through the discontinuous layer of plastisol; and passing the printed plastisol bearing support through a gelation oven.
Claim 2
Dependent Claim
97 words
A process for the manufacture of sheet material having a relief effect on at least a first surface comprising the steps of: printing a decoration on a surface of a support member; applying at least one discontinuous layer of a transparent plastisol over and in registration with at least part of the printed decoration, the plastisol being applied in a thickness of at least ten mils and imparting a desired relief appearance to the printed decoration, the decoration being viewed through the discontinuous layer of plastisol; and passing the printed plastisol bearing support through a gelation oven.
Claim 3
Dependent Claim
20 words
A process as claimed in claim 1 wherein the application of the transparent plastisol is performed by silk screen printing.
Claim 4
Dependent Claim
27 words
A process as claimed in claim 2 further comprising the step of: forming a continuous wear layer over the transparent plastisol before passage through the gelation oven.
Claim 5
Dependent Claim
39 words
A process as claimed in claim 3 wherein the decoration is printed on a deformable support and said process further comprises the step of: laminating the deformable support to a temperature stable support before passage through the gelation oven.
Claim 6
Dependent Claim
27 words
A process as claimed in claim 2 further comprising the step of: forming a continuous wear layer over the transparent plastisol after passage through the gelation oven.
Claim 7
Dependent Claim

Dependent Claim
22 words
A process as claimed in claim 2 wherein the printing of the decoration on the support is performed by a heliographic method.
Claim 9
Dependent Claim
26 words
A process claimed in claim 7 further comprising the step of: forming a continuous wear layer over the transparent plastisol after passage through the gelation oven.
Claim 10
Dependent Claim
27 words

Claim 12
Dependent Claim
28 words
A process as claimed in claim 9 wherein the formation of the wear layer is accomplished by laminating a transparent calendered sheet to the product exiting the oven.
Claim 13
Dependent Claim
19 words

Claim 16
Dependent Claim
39 words
A process as claimed in claim 1 wherein the decoration is, printed on a deformable support and said process further comprises the step of: laminating the deformable support to a temperature stable support before passage through the gelation oven.
Claim 17
Dependent Claim
34 words
A process as claimed in claim 1 further comprising the step of: laminating at least one layer to the product exiting from the gelation oven to impart desired non-visual characteristics to the sheet material.
Claim 18
Dependent Claim
24 words
