Title
(EN) REVERSIBLY THERMOCHROMIC COMPOSITIONS
(FR) COMPOSITIONS THERMOCHROMIQUES RÉVERSIBLES
Abstract
(EN)
A reversible thermochromic system comprising a) a compound of the formula (I) or a tautomer thereof (I) wherein R1 is C1-C18alkyl, C2-C18alkenyl, C3-C12cycloalkyl, C3-C12cycloalkyl substituted by 1, 2 or 3 C1-C4alkyl; or C7-C12phenylalkyl; R2 and R3 are hydrogen or R2 and R3 together form a group -CH=CH-CH=CH-; and R4 is hydrogen, -NO2, -SO2-R1 or (4-nitrophenyl)azo; and b) a compound containing a group of the formula (II).
(FR)
L'invention concerne un système thermochromique réversible comprenant (a) un composé de formule (I) ou un tautomère de celui-ci (I) où R1 représente C1-C18alkyle, C2-C18alcényle, C3-C12cycloalkyle, C3-C12cycloalkyle substitué par 1, 2 ou 3 C1-C4alkyle; ou C7-C12phénylalkyle; R2 et R3 représentent l'hydrogène ou R2 et R3 forment ensemble un groupe -CH=CH-CH=CH-; et R4 représente l'hydrogène, -NO2, -SO2-R1 ou (4-nitrophényl)azo; et (b) un composé contenant un groupe de la formule (II).
