Abstract
Abstract The surface gloss and appearance of vinyl plastisol coatings adhered to substrates are improved by a process comprising passing the coated substrate in cooled condition in contact with a surfacing roll maintained at a temperature of about 320*-420*F and a contact pressure of about 2-100 pounds per linear inch.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
82 words
A method according to claim 1 wherein contact with said polishing roll is carried out by passing the back of the coated substrate in contact with a roll of intermediate hardness through an arch of contact with a roll of intermediate hardness through an arc of contact of about 10*-180* and said polishing roll is arranged to engage with the coated substrate along a line of contact within the subtended angle of the arc of contact of the roll of intermediate hardness.
Claim 2
Dependent Claim
32 words
A method according to claim 2 wherein the substrate is a cellulose or asbestos base having a cellular or foam layer thereon and said wear layer is a transparent vinyl plastisol layer.
Claim 3
Dependent Claim
25 words
A method according to claim 3 wherein said roll of intermediate hardness is a rubber roll and said polishing roll is a chromium plated roll.
Claim 4
Dependent Claim
29 words
A method according to claim 4 wherein said coated substrate is maintained at room temperature and said polishing roll is maintained at a temperature of about 380* to 400*F.
Claim 5
Independent Claim
111 words
A method for the production of a high gloss vinyl coating on a substrate comprising: a. coating a substrate with a vinyl coating; b. heating said coated substrate to a temperature sufficient to fuse said coating; c. cooling the substrate having the thus-fused coating thereon to a temperature not exceeding about 150*F; and d. passing said cooled, coated substrate in contact with a polishing roll maintained at a temperature of from about 320*F to about 420*F, said polishing roll being maintained at a contact pressure of from about 2 to about 100 lbs. per linear inch, whereby a high gloss vinyl coating of enhanced appearance is obtained on the treated substrate.
Claim 6
Dependent Claim
78 words
A method according to claim 6 wherein contact with said polishing roll is carried out by passing the back of the coated substrate maintained at about room temperature in contact with a roll of intermediate hardness through an arc of contact of about 10* to 180* and said polishing roll is arranged to engage with the coated substrate along a line of contact within the subtended angle of the arc of contact of the roll of intermediate hardness.
Claim 7
Dependent Claim
32 words
A method according to claim 7 wherein the substrate is a cellulose or asbestos base having a cellular or foAm layer thereon and said wear layer is a transparent vinyl plastisol layer.
Claim 8
Dependent Claim
26 words
A method according to claim 8 wherein said first roll of intermediate hardness is a rubber roll and said polishing roll is a chromium plated roll.
Claim 9
Dependent Claim
29 words
A method according to claim 9 wherein said coated substrate is maintained at room temperature and said polishing roll is maintained at a temperature of about 380* to 400*F.
Claim 10
Dependent Claim
25 words
A method according to claim 8 wherein the vinyl plastisol coated substrate is fused at a temperature of about 350*-400*F. for 3 to 4 minutes.
Claim 11
Dependent Claim
27 words
A method according to claim 11 wherein the vinyl plastisol layer has a thickness of about 0.005-0.025 inch and the cellular layer is a polyvinyl chloride layer.
Claim 12
Dependent Claim
28 words
A method according to claim 12 wherein the coated sheet is embossed by contact with an embossing roll after fusing and prior to contact with the polishing roll.
