    • Novel reaction media for electron donating and electron accepting components in colour- change compositions are described. The compound is of formula (I): wherein R 1 , and R 2 are selected from a linear or branched alkyl group, alkenyl group, alkoxy group, aryl group and an alkylene aryl group having from 6 to 22 carbon atoms; X 1 and X 2 are selected from -OC(O)-, -CO 2 - and O; R 3 , R 4 and R 5 are selected from hydrogen and an linear or branched alkyl group, cycloalkyl group, alkenyl group, alkoxy group, aryl and alkylene aryl group; R 6 is selected from hydrogen, R 3 , -Χ 1 R 1 and aryl and halogen; Y 1 Y 2 Y 3 and Y 4 are selected from hydrogen, R 3 , -OR 3 and halogen; a is 0 to 4; b is 0 or 1; x and y are independently is 0 or 1 provided that where x and y are 0, a is 0 and b is 1 and R 6 is -C0 2 R 1 ; and wherein when a is 0 and b is 1 and R 5 or R 6 is phenyl, R 6 and R 5 respectively are not hydrogen or C 1-7 alkyl. The compounds are useful in ink compositions, writing implements containing the compound and medical and industrial applications in which temperature sensitive colour change may be required.
    • 描述了在变色组合物中用于给电子和电子接受组分的新型反应介质。 该化合物具有式(I):其中R 1和R 2选自直链或支链烷基,烯基,烷氧基,芳基和具有6至22个碳原子的亚烷基芳基; X 1和X 2选自-OC(O) - , - CO 2 - 和O; R3,R4和R5选自氢和直链或支链烷基,环烷基,烯基,烷氧基,芳基和亚烷基芳基; R6选自氢,R3,-X1R1和芳基和卤素; Y1 Y2 Y3和Y4选自氢,R3,-OR3和卤素; a是0到4; b为0或1; x和y独立地为0或1,条件是当x和y为0时,a为0且b为1且R6为-C02R1; 并且其中当a为0且b为1且R 5或R 6为苯基时,R 6和R 5不为氢或C 1-7烷基。 这些化合物可用于油墨组合物,含有化合物的书写工具以及可能需要温度敏感的颜色变化的医疗和工业应用。
