摘要： A thermochromic acrylic synthetic fiber comprising an acrylonitrile polymer in which a thermochromic pigment composition with an average particle diameter of from 0.5 µm to 30 µm is dispersedly contained in an amount of from 0.5% by weight to 40% by weight based on the weight of the polymer, and being made into fibers; the pigment composition containing (a) an electron-donating color-developing organic compound, (b) an electron-accepting compound and (c) a reaction medium that determines the temperature at which the color-developing reaction of the both compounds takes place.
Also disclosed are a processed article of the above thermochromic acrylic synthetic fiber, and a process for producing the thermochromic acrylic synthetic fiber.摘要翻译： 包含丙烯腈聚合物的热致变色丙烯酸合成纤维，其中平均粒径为0.5μm至30μm的热致变色颜料组合物以基于重量的0.5重量％至40重量％的量分散包含 的聚合物，并被制成纤维; 所述颜料组合物含有（a）供电显色有机化合物，（b）电子接受性化合物和（c）确定发生两种化合物的显色反应的温度的反应介质。 还公开了上述热变色丙烯酸类合成纤维的加工品，以及用于制造热变性丙烯酸类合成纤维的方法。

摘要： A reversible thermochromic composition comprises (a) an electron-donating color-developing organic compound, (b) at least one electron-accepting compound selected from alkoxyphenols compounds of the formula
and (c) a compound serving as a reaction medium capable of causing a reversible electron-donating/accepting reaction attributable to components (a) and (b).
This composition has a reversible metachromatic function; in one aspect, it presents a color-developed state when heated from a color-extinguished state and presents the color-extinguished state when cooled from the color-developed state; in another aspect, it begins to develop color during the course of being cooled after having been heated, color development having been triggered by the temperature rise when being heated in a color-extinguished state, and returns to the color-extinguished state after presenting a maximum developed-color density.摘要翻译： 可逆热变色组合物包含（a）给电子显色有机化合物，（b）至少一种选自式（CHEM）的烷氧基苯酚化合物的电子接受性化合物和（c）可用作反应介质的化合物 导致归因于组分（a）和（b）的可逆的给电/接受反应。 该组合物具有可逆的变色功能; 在一个方面，当从彩色熄灭状态加热时呈现显色状态，并且在从显色状态冷却时呈现熄灭状态; 在另一方面，在被加热后的冷却过程中开始发色，由于在熄灭状态下被加热时由于升温而引起显色，并且在显色后返回熄灭状态 最大显色浓度。
