IMAGE FORMATION BY TRANSFER OF A VAPORIZABLE DYE FORMER AND SUBSEQUENT COLOR DEVELOPMENT

摘要

: An image forming process comprising arranging on a support member, in accordance with image signals, image forming particles containing dye former that develops its color in reaction with a color developing agent, and heat-transferring the dye former from the particles to an image receiving substrate. After the heat-transfer step, the color developing agent is caused to adhere to the dye former transferred onto the substrate to provide colored images. The advantages are an increase in the choice of usable image receiving substrates and color development agents; avoidance of fogging; maintenance of color purity; and avoidance of pollution by re-evaporation of the dye former.
