Abstract
A image forming material has a support having thereon a recording layer which is formed of a composition whose solubility in water or in an alkali aqueous solution is altered by the effects of light or heat, and an intermediate layer which is disposed between the support and the recording layer and which has the same function as that of the recording layer and whose sensitivity to light or heat is higher than that of the recording layer.
Claims19
An image forming material, comprising:
- (a) a support;
- (b) a recording layer disposed on the support, the recording layer including at least one composition having a solubility in water or an alkali aqueous solution that is changed when subjected to light or heat so that the recording layer has a solubility in water or the alkali aqueous solution that is changed when subjected to light or heat;
- and
- (c) an intermediate layer disposed between the support and the recording layer, the intermediate layer including at least one composition having a solubility in the same one of water or the alkali aqueous solution as the composition included in the recording layer, which solubility of the compound included in the intermediate layer is changed when subjected to light or heat, wherein the change in solubility of the intermediate layer in water or the alkali aqueous solution when the intermediate layer is subjected to light or heat is greater than that of the recording layer when the recording layer is subjected to light or heat, said image forming material further comprising an infrared absorbent to permit forming an image using an infrared laser.

A method of making an image forming material, comprising the steps of:
- (a) providing a support;
- (b) disposing on the support an intermediate layer that includes a first composition having a solubility in water or an alkali aqueous solution that changes when subjected to light or heat so that the intermediate layer has a solubility in water or the alkali aqueous solution that is changed when subjected to light or heat;
- and
- (c) disposing on the intermediate layer a recording layer that includes a second composition having a solubility in the same one of water or an alkali aqueous solution as the composition included it the intermediate layer, which solubility of the composition included in the recording layer changes when subjected to light or heat, said image forming material further comprising an infrared absorbent to permit formation of an image using an infrared laser, wherein the change in solubility of the intermediate layer in water or in an alkali aqueous solution when the intermediate layer is subjected to light or heat is greater than that of the recording layer when the recording layer is subjected to light or heat.
