ABSTRACT:
Monochromatic or polychromatic photographic images are directly developed on plain paper by a photodielectric selective sublimable dye transfer process.
A photosensitive belt containing a photodielectric material and a binder is exposed to a light image and the exposed parts are then passed in contact with a plain paper together with a carrier of sublimable dye under pressure and the application of an electromagnetic field.
Multicolor images are formed by exposing the original through three separation filters; for example, red, blue and green on three successive areas of the photosensitive belt and each exposed area passed in contact with a plain paper and three successive carriers of sublimable dyes of color corresponding to the separation filters.
