摘要:
A negative-working image forming process which comprises uniformly exposing a photosensitive material comprising a support having thereon a sensitive layer comprising (i) an o-quinonediazide compound and (ii) a second compound, to actinic radiation which is able to convert the o-quinonediazide compound to the corresponding indenecarboxylic acid compound, and subsequent to said uniformly exposing imagewise exposing said exposed photosensitive material to a laser beam to thereby render the indenecarboxylic acid compound of the imagewise exposed areas convert to the corresponding indene compound and developing with an alkaline developing solution to dissolve out the unexposed area to the laser beam, wherein said second compound reduces the rate of dissolution of the laser exposed areas in the developing solution by converting the indenecarboxylic acid to the corresponding indene compound, whereby said image results.

摘要:
Disclosed is a thermal-transfer recording process employing a transfer material and a image-receiving sheet. The transfer material comprises a support film and an image forming layer containing a coloring material and an organic polymer, and the image-receiving sheet comprises a substrate and a photopolymerizable or photosensitive thermal-adhesive layer. The process comprises placing the transfer material on the image-receiving sheet to form a composite; imagewise heating the surface of the support film of the composite using a thermal head; separating the transfer material from the image-receiving sheet leaving the image forming layer in the heated area on the photopolymerizable or photosensitive thermal-adhesive layer to form a colored replica image on the image-receiving layer; and either exposing the whole surface of the photopolymerizable thermal-adhesive layer to radiation to cure the photopolymerizable thermal-adhesive layer; or exposing the whole surface of the photosensitive thermal-adhesive layer and the image forming layer to UV-rays and treating the exposed layer with a developing solution to remove the exposed layer in the area having no colored replica image thereon.

Disclosed is an image forming process employing a light-sensitive image forming material. The image forming material comprises a support, a light-heat conversion layer and an image forming layer, superposed in order. The process comprises the steps of imagewise exposing the image forming material to light so as to increase a bonding strength between the light-heat conversion layer and the image forming layer in the exposed area, pressing a receiving sheet on the light-heat conversion layer, and removing the receiving sheet from the image forming material to form a negative image on the receiving sheet in the unexposed area and to leave a positive image on the light-heat conversion layer in the exposed area. Otherwise, the process comprises the steps of imagewise exposing the image forming material to light so as to decrease a bonding strength between the conversion layer and the image forming layer in the exposed area, pressing a receiving sheet on the conversion layer, and removing the receiving sheet from the image forming material to form a positive image on the receiving sheet in the exposed area and to leave a negative image on the conversion layer in the unexposed area.

摘要:
The present invention provides a thermal transfer sheet comprising a substrate, and a light-to-heat conversion layer containing a substance capable of converting light to heat and a binder, and an image forming layer, which are disposed on the substrate, wherein the binder in the light-to-heat conversion layer is a polyimide resin soluble in an organic solvent. In the thermal transfer sheet provided by the present invention, the light-to-heat conversion layer is not affected by the coating liquid disposed as a layer on the light-to-heat conversion layer. Further, the light-to-heat conversion layer thus formed exhibits high heat resistance and humidity resistance. Accordingly, the thermal transfer sheet of the present invention produces good images with little or no fogging.
