US Patent:

45241287, Jun 18, 1985

Filed:

Oct 24, 1983

Appl. No.:

6/544043

Inventors:

Larry D. Edwards - Rochester NY
Frederick J. Sauter - Rochester NY
George J. Burgmaier - Rochester NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03C 102

US Classification:

430353

Abstract:

Photographic silver halide is spectrally sensitized by means of at least one bleachable spectral sensitizing dye comprising a cyanine dye nucleus and a particular N-methylene substituent. The spectrally sensitized photographic silver halide is useful in a photothermographic material. An image in the photothermographic material, after exposure, is developed and the spectral sensitizing dye is bleached, especially at elevated pH, by heating the photothermographic material to processing temperature.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

C07D41706

US Classification:

544300

Abstract:

A merocyanine dye having the formula: ##STR1## wherein: R. sub. 1 and R. sub. 2 independently are H, alkyl, alkoxy or aryl R. sub. 7 and R. sub. 8 are H or any of R. sub. 1 and R. sub. 2, R. sub. 1 and R. sub. 7, R. sub. 2 and R. sub. 8 can together comprise the atoms necessary to form a fused aromatic ring on the benzene radical to which they are attached; R. sub. 5 and R. sub. 6 comprise alkyl of from 1-18 carbon atoms provided that the sum of the carbon atoms in R. sub. 5 and R. sub. 6 is at least 8; R. sub. 9 is an alkylene group of 2-9 nuclear carbon and hetero atoms; and Z. sup. + is a cation. This dye is useful in a method for inactivating viruses comprising contacting the viruses with the compound and exposing the resulting mixture to visible light to excite and inactivate the viruses. The compounds are also useful in the irradiation-induced inactivation of leukemia cells.
