Title (EN) THERMOCHROMIC PIGMENT COMPOSITIONS
(FR) COMPOSITIONS DE PIGMENT THERMOCHROME
Abstract:
(EN) The present invention relates to a thermochromic pigment composition comprising: (A) at least one electron-donor organic dye compound, (B) at least one electron-acceptor compound, and (C) at least one compound corresponding to the following formula (I): in which: X is 0 or a single bond, Z is COO or OCO, R1 is O-alkyl or (CH2)mCH3, - R2 is OCO(CH2)nCH3 or H, - y = 0-3, - m = 12-18, - n = 12-18, - p = 8-18, and on the condition that, when X is 0, y is other than 0. The present invention also relates to thermochromic pigment microcapsules comprising descompositions according to the invention, to ink compositions comprising such thermochromic pigment microcapsules, and finally to writing instruments comprising such ink compositions.
(FR) La présente invention concerne une composition de pigment thermochrome comprenant : (A) au moins un composé organique colorant donneur d'électrons, (B) au moins un composé accepteur d'électrons, et (C) au moins un composé répondant à la formule (I) suivante : dans laquelle : X représente 0 ou une liaison simple, Z représente COO ou OCO, R1 représente O-alkyle ou (CH2)mCH3, - R2 représente OCO(CH2)nCH3 ou H, - y = 0-3, - m = 12-18, - n = 12-18, - p = 8-18, et à la condition que lorsque X représente 0, y soit différent de 0. La présente invention vise également des microcapsules de pigment thermochrome comprenant descompositions selon l'invention, des compositions d'encre comprenant de telles microcapsules de pigment thermochrome, et enfin des instruments d'écriture comprenant de telles compositions d'encre.
