Title: Imaging material and manufacture thereof
Inventor: SUZUKI NAOYO
IPC: B41M5/26
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To reduce the residual color of an abrasion part and enhance the durability of an imaging material by applying an imaging layer on a support and setting heating temperature and moistening temperature halfway through the removal of a solvent and/or during heat-curing after the removal at a specific value or above. SOLUTION: The imaging material is formed of a protecting layer 4 laminated on an imaging layer 2 having a coloring material on a support 1. An image is formed using a sheet, to which an image is transferred, with an image receiving layer formed on the support 1. The imaging layer 2 has a coloring material which absorbs a wavelength light of an exposure light source and a binder resin which retains the coloring material. After the imaging layer 2 is applied and dried, it is thermally cured in such a state that it is moistened at 50 RH% or above and the moistening conditions are 30 deg.C or above and the heat-curing time is 12 hours or more.  Thus it is possible to reduce the residual color of an abrasion part and avoid the deterioration of an image quality by enhancing the durability of the imaging material and the tendency to make a device oversized and high-priced due to the increase of required exposure energy.
