Patent ID: 7122290

Claim:
A hologaphic storage medium comprising: a thermally crosslinked polysiloxane binder; a photoactive material; and a photo-initiator, wherein the photoactive material has a concentration that remains about the same before and after a thermal cure process to form the thermally crosslinked polysiloxane binder, and wherein the thermally crosslinked polysiloxane binder is formed from a completely linear monomer, oligomer, or combination of monomer and oligomer that consists of at least one of a poly (methyl methyl siloxane); a poly (methyl phenyl siloxane); or poly (acryloxypropyl) methyl siloxane, wherein the photoactive material comprises an epoxide comprising cyclohexene oxide; cyclopentene oxide; 4-vinylcyclohexene oxide; 4-alkoxymethylcyclohexene oxides; acyloxymethylcyclohexene oxides; 3,4-epoxycyclobexylmethyl-3,4-epoxycyclohexanecarboxylate; 1,3-bis(2-(3,4-epoxycyclohexyl)ethyl)-1,1,3,3-tetramethydisiloxanc; 2-epoxy-1,2,3,4-tetrahydronaphthalene; derivatives capable of being prepared from the foregoing epoxides; or combinations comprising one of the foregoing epoxides.
