Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 48 words
A silane dye composition having the formula ##STR14## wherein Q is a fluorescent dye group; Z is a C 1-30 hydrocarbon radical; R is a hydrogen atom or a C 1-12 hydrocarbon radical; and G is a functional group capable of reacting with a silicone polymer functional group.
Claim 2
Dependent Claim 48 words
A silane dye composition having the formula ##STR14## wherein Q is a fluorescent dye group; Z is a C 1-30 hydrocarbon radical; R is a hydrogen atom or a C 1-12 hydrocarbon radical; and G is a functional group capable of reacting with a silicone polymer functional group.
Claim 3
Dependent Claim 24 words
The composition of claim 1 wherein G is an unsaturated organic functional group selected from the class of vinyl, alkyl, methallyl, or butenyl radicals.
Claim 4
Dependent Claim 27 words
The composition of claim 1 wherein Q is a fluorescent dye selected from the group of polynuclear aromatic dyes composed of pyrene, perylene, benzopyrlene and derivatives thereof.
Claim 5
Dependent Claim 53 words
The dye composition of claim 1 wherein G is a radical of the formula ##STR15## where R is a hydrogen atom or a C 1-12 hydrocarbon radical; n is a whole number of from 1 to 50; and V 1 , V 2 and V 3 are independently a silicone polymer reactive substituent.
Claim 6
Dependent Claim 33 words
The composition of claim 4 wherein the V 1 , V 2 and V 3 silicone polymer reactive groups are selected from the class of radicals consisting of alkoxy, acyloxy or amine groups.
Claim 7
Dependent Claim 8 words

Claim 8
Dependent Claim 7 words
The composition of claim 5 comprising methyl(pyrenyl)dimethylethyl(triethylsiloxy)silane.
Claim 9
Independent Claim 106 words
A method of preparing a dye-silane composition comprising reacting a substituted polynuclear aromatic hydrocarbon based fluorescent dye of the formula: Q-Z-M wherein Q is a polynuclear aromatic fluorescent dye moiety, Z is a C 1-30 hydrocarbon radical, and M is a silane reactive substituent selected from the group consisting of halogen, hydroxyl, carboxyl, amine, and amide groups; with an unsaturated organo functional silane having the formula: ##STR16## wherein X is selected from the group of hydrogen, hydroxyl, and halogen radicals; R is a hydrogen atom or a C 1-12 hydrocarbon radical and A is an alkenyl group to form the dye silane of the formula ##STR17##
Claim 10
Independent Claim 106 words
A method of preparing a dye-silane composition comprising reacting a substituted polynuclear aromatic hydrocarbon based fluorescent dye of the formula: Q-Z-M wherein Q is a polynuclear aromatic fluorescent dye moiety, Z is a C 1-30 hydrocarbon radical, and M is a silane reactive substituent selected from the group consisting of halogen, hydroxyl, carboxyl, amine, and amide groups; with an unsaturated organo functional silane having the formula: ##STR16## wherein X is selected from the group of hydrogen, hydroxyl, and halogen radicals; R is a hydrogen atom or a C 1-12 hydrocarbon radical and A is an alkenyl group to form the dye silane of the formula ##STR17##
Claim 11
Dependent Claim 72 words
The process of claim 8 wherein the resulting unsaturated organo silane dye is further reacted with a hydride functional silane of the formula: ##STR18## in an addition reaction with the unsaturated A group to form ##STR19## wherein n is a whole number from 1 to 50 and V 1 V 2 and V 3 are independently a silicone polymer reactive substituent selected from the class consisting of alkoxy, acyloxy and amine radicals.
Claim 12
Dependent Claim 23 words
The process of claim 8 wherein the alkenyl group A is selected from the group consisting of vinyl, allyl, methallyl, and butenyl radicals.
Claim 13
Dependent Claim 12 words
