There are described thermal imaging members and thermal imaging methods utilizing unsymmetrical rhodamine compounds. The rhodamine color-forming compounds exhibit a first color when in a crystalline form and a second color, different from the first color, when in an amorphous form.

Thermal imaging members and methods

There are described novel rhodamine color-forming compounds. The rhodamine color-forming compounds exhibit a first color when in a crystalline form and a second color, different from the first color, when in an amorphous form. Thermal imaging members containing these color-formers are also described.

Color-forming compounds and use thereof in imaging members and methods

There are described novel rhodamine dye compounds and imaging members and imaging methods, including thermal imaging members and imaging methods, utilizing the compounds. The dye compounds exhibit a first color when in the crystalline form and a second color, different from the first color, when in the liquid, amorphous form.

Dyes and use thereof in imaging members and methods

There are described novel complexes formed between hydrogen bond acceptors and phenolic dye compounds and imaging members and imaging methods, including thermal imaging members and methods utilizing the complexes.

Dye complexes and use thereof in imaging members and methods

There are described novel fluorescein dye compounds and imaging members and imaging methods utilizing the compounds. The fluorescein dye compounds exhibit a first color when in the crystalline form and a second color, different from the first color, when in the liquid, amorphous form.

Dyes and use thereof in thermal imaging members and methods

Process for the preparation of novel dyes for use in imaging members

There are described metal-complexed azo dyes which are useful in ink jet printing applications. Also described are ink jet ink compositions including a dye of the invention as well as ink jet printing methods and apparatus.

Azo metal-complexed dyes, ink jet ink compositions and ink jet printing methods

There are described novel rhodol dye compounds The dye compounds exhibit a first color when in the crystalline form and a second color, different from the first color, when in the liquid, amorphous form.

Dyes

A self-developing diffusion transfer photographic film unit which includes a latent image which becomes visible upon photographic processing of the film unit. The latent image is formed with a chemical compound such as an indicator dye and the visible image formed from the latent image as a result of photographic processing may be transient or permanent. Also described are diffusion transfer photographic methods.

Diffusion transfer photographic film unit

There are described novel photographic processing compositions, film units and processes for use in diffusion transfer photographic systems. More particularly, there is described a method for forming a diffusion transfer image photographic processing of diffusion transfer photographic film units in the presence of hypoxanthine and inosine. Diffusion transfer photographic systems utilizing the novel photographic element or method of the present invention exhibit substantially fewer, if any, crystals on the final image of the finished photograph post-processing.

Photographic element and method

There is described a photographic system wherein development of an exposed photosensitive element is carried out in the presence of an acylpyridine-N-oxide compound.

Photographic system

This invention relates to photographic light-sensitive silver halide emulsions wherein the silver grains are spectrally sensitized to near infrared radiation at wavelengths above 700 nm with a particular class of cyanine dyes and to photographic elements and film units employing such emulsions.
