FORMING METHOD FOR NEAR-INFRARED COLOR ERASING IMAGE AND ITS COLOR ERASING METHOD

摘要

PURPOSE: To provide a forming method of an image capable of forming the image which is excellent in light fastness by erasing color quickly by irradiating it with near-infrared rays and its color erasing method. ;CONSTITUTION: A forming method of a near-infrared color erasing image is obtained wherein an image is formed on an image base material having a color erasing agent layer at least on its surface with a color toner wherein infrared absorptive dye is mixed in binding resin. Another forming method of the near- infrared color erasing image is obtained wherein after forming an image on an image base material with the abovementioned color toner by the binding resin, a color erasing agent layer is formed at least on the formed image. A color erasing method is obtained wherein the image formed by the forming method of the near-infrared color erasing image is heated at a glass transition temperature of the binding resin or higher and irradiated with near infrared rays.;COPYRIGHT: (C)1993,JPO&Japio
