Document Type and Number:
Japanese Patent JPH06509884
Kind Code:
A
Abstract:
This invention relates to a full-color hard copy imaging system and a process, where a multiply photosensitive donor sheet, comprising clear polymeric or an opaque paper base, coated sequentially with a first layer of patches of a cyan, a magenta, and a yellow dye, that are thermally diffusible, with a second layer also coated sequentially with patches of a red light sensitive, a green light sensitive or a blue light sensitive, negative or a positive working photoresist layer, in such a manner that each of the colored dye patches are in registry with their complementary color sensitive photoresist patches, is exposed with white light sequentially, three times in registry on the three primary light sensitive patches, through a multicolor image (a positive transparency or a photographic negative), to produce crosslinks, image wise, in the exposed areas in the case of the negative resist system, or to uncrosslink the resist structure image wise in the exposed areas for a positive working resist system. In the second step, the first color patch is laminated on to a receiver sheet that is composed of a clear plastic layer in which the chromogenic dyes are soluble, with or without a white reflective backing and the first color image is transferred to the receiver sheet by thermal evaporation. The image is formed due to the hindrance of diffusion of dye in the crosslinked regions of the resist layer in the donor sheet. In subsequent consecutive steps the two remaining color images are transferred, by similar thermal process in registry on to the receiver sheet, thereby forming a full-color image of the original image.
