A method for preparing a direct imaging material, the method comprising:
- providing a binder, a dye, a color developer, and an antenna,
- wherein the antenna is soluble in the binder and selected from the group consisting of compounds comprising a phthalocyanine chromophore and compounds comprising a naphthalocyanine chromophore;
- wherein the dye changes color when reacted with the color developer;
- and
- wherein one of the dye and the color developer is soluble in the binder at ambient conditions;
- dissolving the antenna and the binder soluble compound in the binder;
- and
- substantially uniformly distributing the other of the dye and the color developer compound in the binder.
