MATERIAL AND METHOD FOR COPYING

摘要

PURPOSE:To permit copying on plain paper as well by providing microcapsules enveloping a coloring agent, photosensitive foaming agent and binder on a base. CONSTITUTION:The microcapsules 5 enveloping the coloring agent 2, photosensitive foaming agent 3 and heat sensitive binder 4 by a wall material are densely arrayed and stuck onto the base 1. An intermediate adhesive layer 6 may be provided thereto as necessary in order to increase the adhesive power of the capsules to the base. The base having heat resistance is preferred and the thickness thereof is preferably 1-20mum. Copying is thus executed by the simple means for exposing and uniform heating and the copying on plain paper is possible as well without selecting materials to be copied.
