Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
53 words
A vinyl coating solution for treating a foam material to provide a vinyl film coat thereon which comprises: a vinyl copolymer, a chlorinated hydrocarbon solvent, a vinyl solvating solvent, and a plasticizer, said vinyl copolymer being a high acetate content vinyl choride copolymer, said solution having a flash temperature above about 150° F.
Claim 2
Dependent Claim
53 words
A vinyl coating solution for treating a foam material to provide a vinyl film coat thereon which comprises: a vinyl copolymer, a chlorinated hydrocarbon solvent, a vinyl solvating solvent, and a plasticizer, said vinyl copolymer being a high acetate content vinyl choride copolymer, said solution having a flash temperature above about 150° F.
Claim 3
Dependent Claim
28 words
The vinyl coating solution as defined in claim 1 wherein said vinyl solvating solvent is selected from the group consisting of methyl isobutyl ketone, cyclohexanone, and solutions thereof.
Claim 4
Dependent Claim
25 words
The vinyl coating solution as defined in claim 1 wherein said vinyl copolymer constitutes of from 15 to 25 percent by weight of said composition.
Claim 5
Dependent Claim
16 words
The vinyl coating solution as defined in claim 4 wherein said plasticizer is a monomeric plasticizer.
Claim 6
Dependent Claim
20 words
The vinyl coating solution as defined in claim 1 wherein said plasticizer is a blend of monomeric and polymeric plasticizers.
Claim 7
Dependent Claim
26 words
The vinyl coating solution as defined in claim 1 wherein said chlorinated solvent is selected from the group consisting of methylene chloride, 1,1,1-trichloroethane and solutions thereof.
Claim 8
Dependent Claim
17 words

Claim 9
Dependent Claim
78 words
A process for treating a foam material to provide a vinyl film thereon which comprises coating said foam material with a vinyl coating solution formed by admixing a vinyl copolymer and plasticizer therefor in a solvent system having a flash temperature above about 150° F. and including a chlorinated hydrocarbon solvent and a vinyl solvating solvent and the reafter applying said composition of matter to said foam material at a temperature of from 50° to about 140° F.
Claim 10
Dependent Claim
78 words
A process for treating a foam material to provide a vinyl film thereon which comprises coating said foam material with a vinyl coating solution formed by admixing a vinyl copolymer and plasticizer therefor in a solvent system having a flash temperature above about 150° F. and including a chlorinated hydrocarbon solvent and a vinyl solvating solvent and the reafter applying said composition of matter to said foam material at a temperature of from 50° to about 140° F.
Claim 11
Dependent Claim
21 words
The process as defined in claim 8 and including the step of pretreating said foam material to clean the surface thereof.
Claim 12
Dependent Claim
23 words
The process as defined in claim 8 wherein said vinyl copolymer constitutes of from 15 to 25 percent by weight of said composition.
Claim 13
Dependent Claim
26 words
The process as defined in claim 8 wherein said plasticizer is a monomeric plasticizer, and further including the step of overlaying said foam with a fabric.
