There are described novel rhodamine dye compounds and imaging members and imaging methods, including thermal imaging members and imaging methods, utilizing the compounds. The dye compounds exhibit a first color when in the crystalline form and a second color, different from the first color, when in the liquid, amorphous form.
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 an amorphous form that has 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 an amorphous form can be effected by laser exposure.

There are described novel rhodamine color-forming compounds. The rhodamine color-forming compounds exhibit a first color when in a crystalline form and a second color, different from the first color, when in an amorphous form. Thermal imaging members containing these color-formers are also described.
A packaging material, having at least one optically anisotropic layer which is made from substantially the same layer-forming composition and includes two or more regions different in birefringence property.
There are described thermal imaging members and thermal imaging methods utilizing unsymmetrical rhodamine compounds. The rhodamine color-forming compounds exhibit a first color when in a crystalline form and a second color, different from the first color, when in an amorphous form.
