DYE SENSITIZED PHOTOGRAPHIC IMAGING SYSTEM |
摘要 |
DYE SENSITIZED PHOTOGRAPHIC IMAGING SYSTEM A photographic imaging system is disclosed comprised of an imaging dye or A precursor thereof, a hardenable organic component containing ethylenic unsaturation sites and capable of imagewise modulating mobility of the dye or dye precursor as a function of addition at the sites of ethylenic unsaturation, and coinitiators for ethylenic addition. The coinitiators include an azinium salt activator and a photosensitizer which is a dye exhibiting a reduction potential which in relation to that of said ionized azinium salt activator is at most 0.1 volt more positive, with the further proviso that, when the photosensitizer is a keto dye having its principal absorption peak at a wavelength shorter than 550 nm, it exhibits when excited by imaging radiation an intersystem crossing efficiency to a triplet state of less than 10 percent.
