Abstract:
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.

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.
Abstract:
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.

A method of forming a spacer for supporting two substrates which constitute a liquid crystal panel, wherein the spacer is disposed between the two substrates, at least one of which has thereon an alignment layer which has been subjected to aligning treatment, comprising the steps of: (1) laminating the substrate having the alignment layer on a transfer sheet comprising projections of substantially uniform thickness on a temporary support in such a manner that the projections closely contact the alignment layer, and (2) peeling-off the temporary support to transfer the projections onto the alignment layer. The inventive method forms a spacer through a simple step and at a uniform density, and prevents damage of an aligning layer.
