A light- and heat-sensitive composition which contains a photo-hardenable composition and at least one dye, a light- and heat-sensitive recording material which contains a support having the composition provided on at least one side thereof, and an image-forming process using the recording material are disclosed. |

DETAILED DESCRIPTION OF THE INVENTION The term "photo-hardenable composition" as used herein means a photo-hardenable composition selected from among the group consisting of a photo-polymerizable composition comprising an ethylenically unsaturated compound and a photo polymerization initiator, a composition containing a photo-crosslinkable resin, and a mixture thereof.
According to the present invention, an image is obtained by a method comprising imagewise exposing a photo-hardenable composition containing a dye capable of losing its color upon heating, which may be utilized as a spectrally sensitizing dye, to set the composition, and then uniformly heating it to cause the dye to lose its color in the non-set portions, or a method comprising imagewise heating the photo-hardened composition containing the dye to cause the dye to lose its color, and then exposing to set the unheated portions.
In the photo-set portions, the thermal decomposition reaction of the dye is so slow that the dye does not lose its color, so that an image is formed.
In the present invention, a spectrally sensitizing dye in the unexposed portions loses its color, whereas the dye in photo-set portions maintains its color to form an image.
Hence, a mono-sheet type light-sensitive material, which is difficult to obtain with the conventional process of allowing spectrally sensitizing dyes not to maintain their color, can be obtained by the present invention.
The recording materials of the present invention may be prepared in various forms depending upon the end use.
One preferable form is one wherein a layer comprising a photo-hardenable composition, a spectrally sensitizing dye and a binder is provided on a support.
Another preferable form is one wherein fine droplets, containing a light- and heat-sensitive composition comprising a photo-hardenable composition and a spectrally sensitizing dye, are provided on a support.
In this case, the droplets may be the core substance within microcapsules.
The recording material of the present invention may be either a monocolor (a so-called B/W type recording material) or a full-color recording material
