A thermal transfer material is provided which has a support on which a light-to-heat conversion layer and an image forming layer are provided, wherein a smoothster value of the surface of the image forming layer is no more than 2 mmHg, and a center line average surface roughness Ra thereof is in a range of 0.03 to 0.2 &mgr;m. Also provided is a laser thermal transfer recording method in which the thermal transfer material and a thermal transfer image receiving material are laminated to each other to produce a laminate. Further provided is a laser thermal transfer recording method in which the thermal transfer material and a thermal transfer image receiving material are laminated to each other to produce a laminate, the laminate is irradiated with a multi-mode semiconductor laser, the thermal transfer material and the thermal transfer image receiving material are peeled from each other, and an image is thereby formed on the thermal transfer image receiving material.

Thermal transfer material and laser thermal transfer recording method

An image formation process uses two light-sensitive elements comprising first and second adhesive light-sensitive layers which become nonadhesive upon exposure to light, respectively, and first and second toner elements comprising toner layers (a') and (b') of hues (a) and (b), respectively. The process steps include: A) imagewise exposing the first light-sensitive layer; B) contacting the first light-sensitive layer with layer (a') in the first toner element; C) separating the first toner element and the first light-sensitive element, transferring the toner layer portion corresponding to the unexposed portion of the light-sensitive layer to the light-sensitive layer and leaving the toner layer portion corresponding to the exposed portion of the light-sensitive layer on the support for the first toner element; D) contacting the adhesive surface of an image receiving element with the surface of the toner layer of the first toner element on which the toner layer has been left corresponding to the exposed portion of the first light-sensitive layer; E) separating the image receiving element and the first toner element, transferring the toner layer to the image receiving element; F) repeating A) to C) with the second light-sensitive element and toner element, respectively; and G) contacting the surface of the transferred toner layer of the image receiving element on which the hue (a) toner layer has been transferred with the surface of the hue (b) toner layer and separating the image receiving element and the second toner element, transferring the hue (b) toner layer to the image receiving element.

An image formation process uses two light-sensitive elements comprising first and second adhesive light-sensitive layers which become nonadhesive upon exposure to light, respectively, and first and second toner elements comprising toner layers (a') and (b') of hues (a) and (b), respectively. The process steps include:

An electronic still camera in which as a recording medium, for example, at least either one of a semiconductor memory, an optical memory, and a magnetic memory is selected so as to record a video signal therein. Through the selection of the recording medium, it is possible to desirably set the recording speed and the recording capacity.

Electronic still camera capable of selecting recording media

An information recording medium comprising in order, a glass substrate; a layer for preventing diffusion of alkali metal ions and alkaline earth metal ions from the substrate; a thermal barrier layer, and an information recording layer for writing and/or reading information by means of laser beam.

Information recording medium using laser beam

An image-forming method is described using a light-sensitive material comprising a support and a light-sensitive layer on the support, said light-sensitive layer containing an o-quinonediazide compound as a first component and a basic carbonium dye as a second component; according to this method images can be obtained both by positive working and negative working techniques. Furthermore, images which are free from yellow light fogging can be obtained by use of a laser beam.
