PURPOSE:To prevent curling and to enhance conveyability at the time of heating development and transfer by disposing >=1 layers of back layers contg. hydrophilic colloid to the rear face of a base provided with a dye fixed layer and incorporating specific polymer particles into at least one back layer. CONSTITUTION:>=1 Layers of the dye fixed layers contg. a mordant are provided to one side on the base and >=1 layers of the back layers contg. the hydrophilic colloid are disposed on the opposite side. Polymer particles having the glass transition point ranging 20-160 deg.C are incorporated into at least one back layer. A base or base precursor is incorporated into the dye fixed layers or the adjacent layers thereof and a transparent film is preferably used for the base. Curling of the dye fixing element is thereby prevented. For example, the curling to the dye fixed layer side on an OHP is suppressed and the conveyance is smoothed; particularly, the folding of the front end during a heating treatment is prevented. The effect of preventing the curling is further enhanced by making combination use of colloidal silica for the above-mentioned polymer latex. |
