Title: NOVEL COMPOUNDS OF FORMULA (I) AND USE THEREOF IN THERMOCHROMIC PIGMENT COMPOSITIONS
Abstract:
The present invention relates to novel compounds of formula (I) : in which: X is CHR2, O, OCO or CH=CH; Y is O, COO or OCOO; R1 is H or (CH2)PCH3; R2 is a phenyl group or H; m = 12-18; n = 0-14; p = 12-18; and on the condition that, when n = 0, X is CHR2 or CH=CH. The present invention also relates to thermochromic pigment compositions comprising compounds of formula (I) according to the invention, to thermochromic pigment microcapsules comprising such thermochromic pigment compositions, to ink compositions comprising such thermochromic pigment microcapsules, and finally to writing instruments comprising such ink compositions.
