Title
(EN) COLOUR FORMING COMPOSITIONS
(FR) COMPOSITIONS DE FORMATION DE COULEUR
Abstract
(EN)
A composition for forming an image on or within a substrate, the composition comprising: (a) an activatable component capable of transitioning from a non-coloured state to a coloured state, the transition being effected by the application of an applied transition stimulus, wherein the activatable component requires activation to allow transitioning to occur, where said activation occurs by application of an activation temperature; and (b) two additional components each capable of transitioning from a non-coloured state to a coloured state, the transition being effected by the application of an additional applied stimulus or an additional temperature; wherein, if formed, the coloured states of the activatable component and each of the two additional components are different in colour.
(FR)
La présente invention concerne une composition servant à former une image sur un substrat ou à l'intérieur d'un substrat, la composition comprenant : (a) un composant activable capable de passer d'un état non coloré à un état coloré, la transition étant effectuée par l'application d'un stimulus de transition appliqué, le composant activable nécessitant une activation pour que la transition ait lieu, ladite activation se produisant par l'application d'une température d'activation ; et (b) deux composants supplémentaires étant chacun capable de passer d'un état non coloré à un état coloré, la transition étant effectuée par l'application d'un stimulus appliqué supplémentaire ou d'une température supplémentaire. S'ils sont formés, les états colorés du composant activable et chacun des deux composants supplémentaires sont de couleurs différentes.
