METHOD OF FORMING AN IMAGE ON A SUBSTRATE |
| 摘要 |
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 colour-change agents, i.e. a first colour-change agent capable of giving rise to at least two different colours; and a second colour-change agent capable of giving rise to at least one different colour than achievable with the first colour 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. |

1. A method of forming an image on a substrate in or on which there are at least two different colour-change agents, i.e.
a first colour-change agent capable of giving rise to at least two different colours; and a second colour-change agent capable of giving rise to at least one different colour than achievable with the first colour change agent; and which comprises applying energy to the substrate so as to generate an image. |
