Patent ID: 7820356

Claim:
A photo-induced thermally developable film comprising: a polymer matrix having a form of a layer in a solid phase and having a first refractive index; at least one monomer compatible with the polymer matrix and having a second refractive index different from the first refractive index; a procatalyst, where the procatalyst is convertible to a latently active form, the latently active form of the procatalyst is convertible to an active form, and the active form of the procatalyst is capable of polymerizing the at least one monomer; and a cocatalyst, where the cocatalyst is suitable for converting the procatalyst to the latently active form upon exposure to actinic radiation and the latently active form is convertible to the active form upon heating to a first temperature, where the monomer, procatalyst and cocatalyst are dispersed in the layer of the polymer matrix.
