Abstract

A method of forming an image on a substrate by applying energy, involves a substrate in or on which there are at least two different color-change agents, i.e. a first color-change agent capable of giving rise to at least two different colors; and a second color-change agent capable of giving rise to at least one different color than achievable with the first color change agent. A preferred embodiment of the invention is a multi-layer laminate comprising, in order, a layer comprising the first agent, a barrier layer, and a layer comprising the second agent.
