摘要:
A dye transfer apparatus having a stain preventing device. The apparatus comprises a rotatable plate cylinder on which a matrix is mounted, a dye solution applying device for applying a dye solution on the matrix, a washing liquid supplying device positioned downstream of the dye solution applying device, a squeeze roller positioned downstream of the washing liquid supplying device for urging a receiving material into contact with the matrix, and a washing liquid removing device having a head with a narrow tip end disposed closely adjacent the nip of the plate cylinder and the squeeze roller to remove washing liquid containing dye from the surface of the receiving material.

The recording film for charged electron beam recording according to this invention has an electrically conductive coating of RbAg4I5 provided on the recording film. The RbAg4I5 coating exhibits an excellent low surface resistivity in comparison with any conventional coating. The charged electron beam recording film of this invention has, furthermore, a protective coating of water-impermeable resin on the RbAg4I5 coating for preventing it from being attacked by water or moisture.

A PROCESS FOR FORMING AN IMAGE COMPRISING SELECTIVELY EXPOSING A PORTION OF A LIGHT-SENSITIVE MATERIAL, WHICH LIGHT-SENSITIVE MATERIAL COMPRISES A SUPPORT HAVING THEREON A THIN LAYER OF A DYE WHICH HAS AN ADSORPTION IN THE VISIBLE LIGHT REGION AND WHICH BECOMES STABLE TO HEAT WHEN IT IS EXPOSED TO LIGHT HAVING A WAVELENGTH IN THE ABSORPTION REGION OF THE DYE AS COMPARED TO THE UNEXPOSED STATE OF THE DYE, TO LIGHT OF A WAVELENGTH IN THE ABSORPTION REGION OF THE DYE AND, SIMULTANEOUSLY OR IMMEDIATELY AFTER EXPOSURE, HEATING THE LIGHT-SENSITIVE MATERIAL TO FADE THE DYE AT THE UNEXPOSED AREAS.
摘要:
A stable positive image having high contrast is formed in a dry system without the necessity of heat treatment by subjecting a light-developable silver halide light-sensitive material having a layer of silver halide grains having occuluded therein bismuth ions and containing a mercaptan compound to an intense imagewise exposure in a short period of time and then subjecting the light sensitive material to an overall uniform exposure.
