Abstract: A composition susceptible to changing color upon the application of energy, wherein the composition comprises a color former and a tinting colorant, wherein the tinting colorant has a complementary color to that of the composition comprising the color former without tinting colorant. Preferably, the composition 5 also comprises an energy absorbing additive. The invention also provides a method of improving contrast when a composition susceptible to changing color is imaged.
