  • Publication number: 20020015838
    Abstract: A photosensitive transfer sheet which has a support, and on the support, a color material layer. The color material layer contains an inorganic pigment and/or a metal pigment, a binder and a precipitation prevention agent. Since precipitation of pigment is suppressed due to the precipitation prevention agent, uniform color tone can be obtained.

  • Patent number: 6326121
    Abstract: 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.

  • Patent number: 4431725
    Abstract: A light-sensitive material having on a support a light-sensitive layer containing an o-quinonediazide compound as a main component and, additionally, a particular compound represented by the following general formula (I): ##STR1## wherein Z represents the nonmetallic atoms forming a 5-membered ring; X represents S, O, ##STR2## or .dbd.N--R.sub.c (where R.sub.a, R.sub.b and R.sub.c are each a hydrogen atom or an organic group other than a carboxylic acid group); and Y is a hydrogen atom or an organic group other than a carboxylic acid group, is disclosed. This material can provide both positive and negative working images having high resolution and good adhesiveness to the support. A process for producing positive working images includes the steps of imagewise exposure and development processing, while a process for producing negative working images includes the steps of imagewise exposure, heating, uniform (overall) exposure and development processing.
