摘要： A 6-tertiary amino-2-(Z.dbd.CH--)benzofuran dye is disclosed, where Z represents the atoms providing an electron withdrawing group and a conjugated methine linkage completing a resonant dye chromophore including the 6-tertiary amino group as an electron donor and the electron withdrawing group as an electron acceptor. The dyes are formed by condensing a 6-tertiary amino-2-formylbenzofuran with an electron withdrawing dye nucleus precursor containing an active methyl or methylene site. The dyes exhibit bathochromically shifted absorption peaks.

摘要： A photographic imaging system is disclosed comprised of a hardenable organic component containing ethylenic unsaturation sites and coinitiators for ethylenic addition. The coinitiators include an activator and a photosensitizer. The photosensitizer is a 6-tertiary amino-2-(Z--CH.dbd.)benzofuran dye, where Z represents the atoms providing an electron withdrawing carbonyl or sulfonyl group and completing a conjugated methine linkage extending from the electron withdrawing carbonyl group through the benzofuran to the electron donating 6-tertiary amino substituent to form a resonant dye chromophore. The photosensitizers bathochromically extend exposure response of the imaging system.
