Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
77 words
A liquid radiation-curable coating composition adapted to deposit, after radiation curing, an adherent cured coating on a glass surface, comprising a radiation-curable polyethylenic polymeric organic compound, and from about 0.5% to about 5% of the coating composition of a polyalkoxy silane containing an organic substituent which carries a single active hydrogen atom which is capable of reacting with ethylenic unsaturation by Michael adduction and which is selected from the amino hydrogen atom and the mercaptyl hydrogen atom.
Claim 2
Dependent Claim
77 words
A liquid radiation-curable coating composition adapted to deposit, after radiation curing, an adherent cured coating on a glass surface, comprising a radiation-curable polyethylenic polymeric organic compound, and from about 0.5% to about 5% of the coating composition of a polyalkoxy silane containing an organic substituent which carries a single active hydrogen atom which is capable of reacting with ethylenic unsaturation by Michael adduction and which is selected from the amino hydrogen atom and the mercaptyl hydrogen atom.
Claim 3
Dependent Claim
19 words
A coating composition as recited in claim 1 in which said active hydrogen atom is an amino hydrogen atom.
Claim 4
Dependent Claim
19 words
A coating composition as recited in claim 1 in which said active hydrogen atom is a mercaptyl hydrogen atom.
Claim 5
Dependent Claim
18 words
A coating composition as recited in claim 1 in which said radiation-curable polyethylenic polymeric organic compound is acrylate-functional.
Claim 6
Dependent Claim
19 words
A coating composition as recited in claim 4 in which said radiation-curable acrylate-functional polymeric organic compound is a polyurethane.
Claim 7
Dependent Claim
20 words
A coating composition as recited in claim 4 in which said radiation-curable acrylate-functional polymeric organic compound is a polyurethane urea.
Claim 8
Dependent Claim
26 words
A coating composition as recited in claim 1 in which said composition cures to provide a film having a tensile modulus less than about 150,000 psi.
Claim 9
Dependent Claim
26 words
A coating composition as recited in claim 1 in which said composition cures to provide a film having a tensile modulus less than about 10,000 psi.
Claim 10
Dependent Claim
31 words
A coating composition as recited in claim 1 in which said radiation-curable polyethylenic polymeric organic compound is acrylate-functional, and a photoinitiator is present to render said composition curable with ultraviolet radiation.
Claim 11
Dependent Claim
15 words
An optical glass fiber coated with a radiation-cured coating of the composition of claim 1.
Claim 12
Dependent Claim
15 words
An optical glass fiber coated with an ultraviolet-cured coating of the composition of claim 9.
Claim 13
Dependent Claim
19 words
A coated optical glass fiber as recited in claim 11 in which said polyalkoxy silane is gamma-mercaptopropyl trimethoxy silane.
