Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
50 words
The process of formulating a coating containing a cross-linkable base resin, a cross-linking initiator and an effective cross-linking amount of an epoxy divinyl ether compound having the formula ##STR22## wherein x and x' each independently have a value of from 0 to 3 and coating said formulation on a substrate.
Claim 2
Dependent Claim
50 words
The process of formulating a coating containing a cross-linkable base resin, a cross-linking initiator and an effective cross-linking amount of an epoxy divinyl ether compound having the formula ##STR22## wherein x and x' each independently have a value of from 0 to 3 and coating said formulation on a substrate.
Claim 3
Dependent Claim
40 words
The process of claim 1 wherein said formulation is coated on substrate in a thickness of between about 0.02 mil and about 30 mil and is cured thereon at a temperature of between about 25° C. and about 250° C.
Claim 4
Dependent Claim
42 words
The process of claim 2 wherein said formulation is coated on a metal substrate in a thickness of between about 0.5 mil and about 5 mils and is cured thereon at a temperature of between about 50° C. and about 200° C.
Claim 5
Dependent Claim
22 words
The process of claim 1 wherein said coating is cured on the substrate by exposure to a source of radiation or heat.
Claim 6
Dependent Claim
27 words
The process of claim 1 wherein said coating is cured on the substrate by exposure to an electron beam at from about 0.5 to about 5 megarads.
