Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
97 words
A resin rubber laminate comprising: (i) a layer of a rubber composition blend comprising (a) a rubber component and (b) an alkoxysilane compound of the general formula (1): ##STR3## wherein R 1 and R 2 are functional groups, R 3 and R 4 are hydrocarbon groups, said composition blend comprising 100 parts by weight of rubber component (a) to 0.05 to 5 parts by weight of alkoxysilane compound (b) joined to: (ii) a surface-modified layer of a resin: wherein said surface-modified resin layer is surface modified by plasma treatment, corona discharge treatment or exposure to ultraviolet radiation.
Claim 2
Dependent Claim
97 words
A resin rubber laminate comprising: (i) a layer of a rubber composition blend comprising (a) a rubber component and (b) an alkoxysilane compound of the general formula (1): ##STR3## wherein R 1 and R 2 are functional groups, R 3 and R 4 are hydrocarbon groups, said composition blend comprising 100 parts by weight of rubber component (a) to 0.05 to 5 parts by weight of alkoxysilane compound (b) joined to: (ii) a surface-modified layer of a resin: wherein said surface-modified resin layer is surface modified by plasma treatment, corona discharge treatment or exposure to ultraviolet radiation.
Claim 3
Dependent Claim
14 words
The resin/rubber laminate of claim 1 wherein the alkoxysilane compound contains an amino group.
Claim 4
Dependent Claim
17 words
