Abstract:
A method for preparing an image forming material comprising a support and at least an image forming layer, the method comprising the steps of:(i) subjecting at least one side of the support to a corona discharge treatment at 2 to 40 W/m2/min to modify the surface of the support, (i-a) subjecting the surface-modified support to a dust removing treatment which is performed by applying at least one of suction, adhesive-roll, and wiping, and (ii) forming the image forming layer on the surface-modified support by coating, wherein the image forming layer contains a resin containing a polar group selected from the group consisting of a hydroxy group, a carboxylic acid group and a sulfonic acid group and a compound containing an isocyanate group, and the modified surface of the support exhibits a surface energy of 45 to 60 dyne/cm, and wherein at least a part of the image forming layer is adapted to be made removable upon image wise exposure to light, such that the removable image forming layer forms an image when removed.
