Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

C08G 1204

US Classification:

528266

Abstract:

Disclosed are electrically photosensitive polymers in which recurring units contain vinylene-1,4-phenylene-imino-1,4-phenylene-vinylenearylene groups included in the polymer backbone. In one embodiment, the disclosed polymers are employed as the principal electrically photosensitive constituent in migration imaging dispersions and elements. In another embodiment, the polymers are employed as sensitizers for electrically photosensitive colorants having spectral absorption peaks in the 400-500 nm wavelength region of the spectrum. The polymers are employed in migration imaging dispersions and elements.

Abstract:

A method for the synthesis of particular isoquinoline compounds which are useful intermediates in the preparation of members of the family of opium alkaloids, such as morphine and codeine. Steps in the process include the acylation of the isoquinoline nitrogen; reaction of the acylated isoquinoline with a phosphorous compound; and condensation with a benzaldehyde derivative to yield a 1-benzyl isoquinoline.
