  [Problems] An object of the present invention is to provide: a thermochromic color-memory composition which effectively expresses a property of being able to interchangeably memorize and retain colors and which is thus applicable to various fields; and a thermochromic color-memory microcapsule pigment encapsulating the same. [Solution] Provided is a thermochromic color-memory composition including: (a) an electron-donating color-developing organic compound; (b) an electron-accepting compound; and (c) an ester compound represented by the following Formula (1), as a reaction medium which controls color reaction between the component (a) and the component (b): (wherein, R represents an alkyl group having 3 to 18 carbon atoms, a cycloalkylalkyl group having 6 to 11 carbon atoms, a cycloalkyl group having 5 to 7 carbon atoms or an alkenyl group having 3 to 18 carbon atoms; each X independently represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 3 carbon atoms or a halogen atom; and each Y independently represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, a methoxy group, an ethoxy group or a halogen atom).

  问题 本发明的目的是提供：一种热致变色颜色记忆组合物，该组合物能有效表达可互换记忆和保留颜色的特性，因此适用于各种领域；以及一种封装该组合物的热致变色颜色记忆微胶囊颜料。 [解决方案］ 本发明提供了一种热致变色颜色记忆组合物，该组合物包括：(a)一种电子捐赠显色有机化合物；(b)一种电子接受化合物；以及(c)一种由下式(1)表示的酯类化合物，作为反应介质，该反应介质可控制组分(a)和组分(b)之间的颜色反应： (其中，R 代表具有 3 至 18 个碳原子的烷基、具有 6 至 11 个碳原子的环烷基、具有 5 至 7 个碳原子的环烷基或具有 3 至 18 个碳原子的烯基；每个 X 独立地代表氢原子、具有 1 至 4 个碳原子的烷基、具有 1 至 3 个碳原子的烷氧基或卤素原子；每个 Y 独立地代表氢原子、具有 1 至 4 个碳原子的烷基、甲氧基、乙氧基或卤素原子）。
• Non-antibiotic antibacterial activity of dodecyl gallate

  Dodecyl (C-12) gallate (3,4,5-trihydroxybenzoate) (1) was found to possess antibacterial activity specifically against Gram-positive bacteria, in addition to its potent antioxidant activity. The time-kill curve study indicates that this amphipathic gallate exhibits bactericidal activity against methicillin resistant Staphylococcus aureus (MRSA) strains. Dodecyl (lauryl) gallate inhibited oxygen consumption in whole cells and oxidation of NADH in membrane preparation. The antibacterial activity of this gallate comes in part from its ability to inhibit the membrane respiratory chain. As far as alkyl gallates are concerned, their antimicrobial spectra and potency depend in part on the hydrophobic portion of the molecule. (C) 2002 Elsevier Science Ltd. All rights reserved.
