(EN) COLOUR FORMING COMPOSITIONS
(FR) COMPOSITIONS FORMANT DES COULEURS
Abstract
(EN)
A composition for forming an image on or within a substrate, the composition comprising two or more components selected from the following groups (i) to (iii): (i)a component capable of reversibly transitioning between a non-coloured state and a coloured state, the transition from the non-coloured state to the coloured state being effected by the application of a first applied stimulus and the transition from the coloured state to the non-coloured state being effected by the application of a first temperature; (ii)a component capable of transitioning from a non-coloured state to a coloured state, the transition being effected by the application of a second applied stimulus, wherein the component can be deactivated, either before or after transitioning, by application of a second temperature, such that subsequent transitioning cannot occur; (iii) a component capable of transitioning from a non-coloured state to a coloured state, the transition being effected by the application of a third applied stimulus, wherein said component requires activation to allow transitioning to occur, where said activation occurs by application of a third temperature; wherein, if formed,each of the coloured states of the two or more components has a different colour.
(FR)
La présente invention concerne une composition pour former une image sur ou à l'intérieur d'un substrat, la composition comprenant au moins deux composants choisis parmi les groupes (i) à (iii) suivants: (i) un composant capable de passer de manière réversible entre un état non coloré et un état coloré, la transition de l'état non coloré à l'état coloré étant effectuée par l'application d'un premier stimulus appliqué et la transition de l'état coloré à l'état non coloré étant effectuée par l'application d'une première température; (ii) un composant apte à passer d'un état non coloré à un état coloré, la transition étant effectuée par l'application d'un second stimulus appliqué, le composant pouvant être désactivé, avant ou après la transition, par application d'une seconde température, de sorte qu'une transition ultérieure ne peut se produire; (iii) un composant capable de passer d'un état non coloré à un état coloré, la transition étant effectuée par l'application d'un troisième stimulus appliqué, ledit composant nécessitant une activation pour permettre à la transition de se produire, ladite activation se produisant par l'application d'une troisième température; de sorte que s'ils sont formés, chacun des états colorés des deux composants ou plus présentent une couleur différente.
