ABSTRACT:
Compositions and methods for production of color images which are developable at desired wavelengths are disclosed and described. The color forming composition can include a color former which is a spiro dye. The color forming composition can include a radiation antenna admixed with or in thermal contact with the color former. The color forming composition can also be optimized for development using electromagnetic radiation having a selected development wavelength. The color forming compositions are useful in forming images on a wide variety of substrates such as optical disks.
