MICROCAPSULATED TONER AND REGENERATING METHOD OF IMAGE RECEIVING SHEET PRINTED BY USING SUCH MICROCAPSULATED TONER

摘要

PURPOSE:To obtain a regenerated image receiving sheet which permits easy deinking whatoner the image receiving sheets are and is sufficiently reutilizable by providing this microcapsulated toner with a specific core material and shell material which are respectively specific. CONSTITUTION:This microcapsulated toner has at least the core material having reversibly color developable and erasable coloring agents and the shell material consisting of a shellforming resin for coating this core material. Images are formed on the image receiving sheet 14 formed by using such microcapsulated toner and thereafter the microcapsules are broken down to bring a decoloring agent 13 with the exposed coloring agents to make the resulted images invisible. Coloring materials generally known as leuco dyes are usable as the reversibly color developable and erasable coloring agents to be incorporated as the core material of the microcapsulated toner and other oxidation reduction dyes or pigments are usable as well.
