Title (EN) REVERSIBLY ACTIVATABLE DIACETYLENES AND THEIR USE AS COLOUR-FORMERS
(FR) DIACÉTYLÈNES ACTIVABLES DE FAÇON RÉVERSIBLE ET LEUR UTILISATION À TITRE DE CHROMOGÈNES
Abstract: front page image
(EN)A method of forming a coloured substrate, comprising applying to or incorporating within the substrate a diacetylene compound, and exposing the substrate to (i) a first, activating stimulus that converts the diacetylene compound from an unreactive to a reactive form, and (ii) a second stimulus that causes the reactive form of the diacetylene compound to polymerize and form the coloured substrate, wherein the diacetylene compound reverts to its unreactive form on removal of the activating stimulus and is of formula I: Y-C≡C-C≡C-(CH2)n-T-Q-Z (I) wherein: n = an odd integer; T = CO, CS or a bond; Q = NH, S, O, OCONH, NHCONH, NH-CHE-CONH, NHCOO or NHCSNH wherein E is H or a C-1-20 alkyl group; Z = H or a hydrocarbon group containing 1 to 20 carbon atoms; Y = H or any group comprising at least one carbon atom.
(FR)La présente invention concerne un procédé de formation d'un substrat coloré comprenant les étapes consistant à appliquer ou incorporer au substrat un composé de diacétylène, puis à exposer le substrat à (i) un premier stimulus d'activation qui fait passer le composé de diacétylène d'une forme non réactive à une forme réactive et (ii) un second stimulus qui provoque la polymérisation de la forme réactive du composé de diacétylène et l'amène à former le substrat coloré. Le composé de diacétylène reprend sa forme non réactive à la fin du stimulus d'activation et il est représenté par la formule I : :Y-C≡C-C≡C-(CH2)n-T-Q-Z (I) où n = un entier impair ; T = CO, CS ou une liaison ; Q = NH, S, O, OCONH, NHCONH, NH-CHE-CONH, NHCOO ou NHCSNH, avec E = H ou un groupe alkyle C-1-20 ; Z = H ou un groupe d'hydrocarbures contenant de 1 à 20 atomes de carbone ; et Y = H ou un quelconque groupe contenant au moins un atome de carbone.
