Definitions
- the present invention relates to an apparatus for developing and transferring an image.
- the sensitive paper contains a dye, (in the following referred to as "pigment") carrier which reduces at least photo-sensitive silver halide, organic silver salt oxidizer, hydrophilic binder and pigment expelling agent. As a result of a chemical reaction, the photo-sensitive paper expels a hydrophilic pigment.
- a dye in the following referred to as "pigment”
- the thermal developing color photo-sensitive paper is subjected merely to thermal developing after exposure of the image, a silver image is formed in the exposed portion of the paper while the mobile hydrophilic pigment is provided in the portion thereof which corresponds with the silver image.
- the photo-sensitive layer is thus composed of negative photo-sensitive material.
- the thermal developing color photo-sensitive paper is subjected to image exposure and then to thermal developing, and an oxidation-reduction reaction takes place between the organic silver salt oxidizer and the reduceable pigment carrier with the exposed photo-sensitive silver halide acting as a catalyst.
- the silver image is formed in the exposed portion of the photo-sensitive paper.
- the pigment carrier is oxidized into an oxide by the organic silver salt oxidizer.
- the oxide is excised under the presence of the pigment expelling agent, as a result of which the mobile hydrophilic pigment is expelled. Accordingly, the silver image and the mobile hydrophilic pigment are provided in the exposed portion, and a color image can be obtained by transferring the hydrophilic pigment onto the print paper.
- the photo-sensitive layer is made of positive photo-sensitive material
- the silver image and the mobile hydrophilic pigment are provided in the portion of the material which is not exposed.
- the Fig. is a side view of a thermal developing and transferring apparatus operated according to a method in which a melting diffusion agent is applied in advance to a print paper or a thermal developing photo-sensitive paper. After a print paper and an exposed photo-sensitive paper are arranged in layers, the layers are led around a hot drum so that a developing step and a transferring step are simultaneously carried out.
- the apparatus comprises: a hot drum 70 which turns in one direction; a supply roll 71 on which a print paper P is wound; a pair of feed rollers 72 and 72 for feeding exposed thermal developing photo-sensitive paper N in roll form; a guide roller 74 cooperating with a back-up roller 73 to put the photo-sensitive paper N and a print paper P in layers and to abut the layered paper against the hot drum 70; a guide roller 75 and a back-up roller 76 for peeling off the print paper P, onto which the image has been transferred; from the photo-sensitive paper N; a winding roll 77 which is operated with a frictional drive to rewind the used photo-sensitive paper N; and a guide roller 78 for guiding the used photo-sensitive paper N from the hot drum 70 to the winding roll 77.
- the leader of the exposed photo-sensitive paper N which has been passed through the pair of feed rollers 72 and 72, is laid on the print paper P coming from the supply rool 71. Then, these papers are passed between the rollers 73 and 74 and are then wound around the hot drum 70 in such a manner that the paper P is passed between the rollers 75 and 76.
- the leader of the photo-sensitive paper N is passed between the drum 70 and the roller 78 and is then rewound on the winding roller 77. As the hot drum 70 is turned clockwise, the photo-sensitive paper N is heated, so that the exposed part thereof expels a pigment.
- the print paper P is also heated, so that a hydrophilic melting paper such as urea, water of crystallization or a micro-capsule is melted to allow a diffusion agent to ooze out.
- a pigment image is transferred onto the print paper P.
- the print paper P onto which the image has been transferred is removed from the photo-sensitive paper N and is discharged as a hard copy passing between the guide roller 75 and the back-up roller 76.
- the photo-sensitive paper N which has been used is wound on the winding roll 77.
- the hot drum 70 has a silicone rubber heater as a heat source.
- the heater wattage density is made high enough to maintain the peripheral temperature substantially uniform.
