The sensitivity can be further improved by incorporation of a halogen ion source in addition to the halogen molecule. Furthermore, the dry image forming material can be improved, with respect to light stability of the raw image forming material and stabilities to heat and humidity, by incorporation of a nickel compound and/or a cobalt compound. In the dry image forming material of this invention, further incorporation of a carboxylic acid anhydride exerts a remarkable anti-fogging effect. The dry image forming material of this invention is non-photosensitive under normal lighting conditions and therefore, can be prepared, handled and stored in a light room. An image can be easily, simply formed only by preliminary heating, light exposure and heat development of the image forming material. |
