摘要: A process for making a leuco dye coating composition, comprising the steps of:
A. blending a mixture of (a) a leuco Dye, (b) an antioxidant, (c) a [polypoly(ethyleneoxide)block-poly(propyleneoxide)] nonionic block copolymer surfactant, (d) an alkylarlyoxypoly(alkylene oxide) nonionic surfactant and (e) water;
B. milling the blend prepared in step A to prepare a coating composition of the leuco dye in milling media;
C. separating the dye coating composition from the milling media.摘要翻译: 一种制备无色染料涂料组合物的方法,包括以下步骤:A.将(a)无色染料,(b)抗氧化剂,(c)多聚(环氧乙烷)嵌段 - 聚(环氧丙烷) 嵌段共聚物表面活性剂,(d)烷基芳氧基聚(环氧烷)非离子表面活性剂和(e)水; B.研磨在步骤A中制备的共混物,以制备无色染料在研磨介质中的涂料组合物; C.将染料涂料组合物与研磨介质分离。
