ABSTRACT:
An optical recording material which when exposed to actinic radiation produces a change in optical properties in the exposed regions, thereby providing a pattern of intelligence for storing and retrieving information, the recording material having: a) a polymer containing a covalently bound reactant moiety which is capable of undergoing a chemical transformation upon a one electron oxidation, thus causing the change in optical properties in the exposed regions; and b) a sensitizer capable of absorbing actinic radiation to cause an initial one electron oxidation of the reactant.
