Abstract
There are disclosed imaging members wherein a chemical compound in a crystalline form is converted, at least partially, and preferably substantially completely or completely, to a liquid in the amorphous form, the liquid having intrinsically a different color from the crystalline form. Also described are imaging methods utilizing the imaging members. The conversion of the compound from the crystalline form to the liquid form can be effected by the application of thermal energy or by other imaging techniques.
Claims11
A color imaging method comprising the steps of:
- (a) providing a color imaging member comprising a substrate bearing one or more color-forming layers, wherein at least one of said color-forming layers comprises a chemical compound in a crystalline form, said crystalline form being capable of being converted to an amorphous form, said chemical compound having intrinsically a different color in said crystalline form than in said amorphous form;
- and
- (b) converting at least a portion of said
- chemical compound to an amorphous form in an imagewise pattern by heating with a laser, whereby an image is formed.
