DEFINITION

Classification: 430/81

Sensitized or doped:

(under subclass 79) Compositions wherein the carbazole moiety containing compound, etc., contains a material which is specifically named or identified by chemical structure which extends the range of spectral response or increases the radiation sensitivity in the spectral region of inherent sensitivity or regions to which said compound, etc., is spectrally sensitized.
