摘要:
A composition, method, and system for recording an image. The system includes a multiphase imaging material in which energy is absorbed by an antenna material. The absorbed energy causes the reaction of an activator and a color-forming material to form a mark. A fixer is employed to retard the fading of the mark.

Compositions and methods for production of color images which are developable with improved marking sensitivity and image contrast are disclosed and described. Specifically, a color forming composition can comprise a polymeric activator phase including a polymer matrix and an activator dissolved therein, a color former phase including a color former, and a radiation absorber in thermal contact with the color former phase. Particularly, the color former phase can be finely dispersed within the polymeric activator phase at an average particle size of less than 2 μm.

摘要:
Compositions and methods for production of color images using leuco dye-containing color forming compositions are described. The color forming composition can include a color forming leuco dye, a metal salt activator, a suppression agent configured for inhibiting the activity of the metal salt activator until application of energy in the form of heat or light, and an initiator precursor. The initiator precursor is capable of liberating scavenger species which reduce the inhibiting action of the suppression agent. The color forming compositions can be a single phase mixture of a leuco dye, metal salt activator, suppression agent, and initiator precursor which are stable under ambient conditions and form a colored composition upon application of energy.
