Abstract
An exposure apparatus for exposing light-sensitive recording medium through a superposed image original, the exposure apparatus comprising at least one light source, an element transmissive to actinic radiation emitted from the light source positioned between the light source and the image original, the element capable of holding the image original against the heat-developable light-sensitive recording medium, and at least one interference filter disposed between the light source and the image original during exposure. The invention is further directed to an image forming process using the exposure apparatus.
Claims7
A process of forming an image in a heat-developable light-sensitive recording medium,
- said heat-developable light-sensitive recording medium comprising at least one layer containing a light-sensitive composition capable of imagewise curing upon imagewise exposure to actinic radiation to form a latent image and thereafter capable of forming a color image in respective correspondence or counter-correspondence to said latent image in the light-sensitive material by heating to cause movement of components relating to coloring or decoloring,
- said process comprising the steps of:
- superposing an image original against said heat-developable light-sensitive recording medium;
- placing the superposed image original and heat-developable light-sensitive recording medium in an exposure apparatus comprising:
- at least one light source;
- an element transmissive to actinic radiation emitted from said light source positioned between said light source and said image original, said element holding said image original against said heat-developable light-sensitive recording medium;
- and
- at least one interference filter disposed between said light source and said image original during exposure;
- exposing said heat-developable light-sensitive recording medium to actinic radiation emitted from said light source and passing through said interference filter, said transmissive element and said original to form a latent image in said heat-developable light-sensitive recording medium;
- and
- heating said exposed heat-developable light-sensitive recording medium;
- wherein the heat-developable light-sensitive recording medium comprises microcapsules which include an electron donative colorless dye, and a light-curable composition outside said microcapsules which includes an electron acceptive compound and which forms latent images by imagewise exposure, said heat-developable light-sensitive recording medium forming color images in counter-correspondence to said latent images by heating to move said electron acceptive compound.

- and
- at least one interference filter disposed between said light source and said image original during exposure;
- exposing said heat-developable light-sensitive recording medium to actinic radiation emitted from said light source and passing through said interference filter, said transmissive element and said original to form a latent image in said heat-developable light-sensitive recording medium;
- and
- heating said exposed heat-developable light-sensitive recording medium;
- wherein the heat-developable light-sensitive recording medium comprises an electron acceptive component, microcapsules which include an electron donative colorless dye, and a light-curable composition outside said microcapsules which includes a vinyl monomer and which forms latent images by imagewise exposure, said heat-developable light-sensitive recording medium forming color images in correspondence to said latent images by heating to move at least said vinyl monomer.
