摘要： A thermochromic leuco dye composition contains a leuco dye moiety including one or more tri-aryl substituted pyridines, a UVA developer moiety including at least one UVA developer selected from the group consisting of salicylic acid and derivatives thereof, and biphenyls and derivatives thereof, and a carrier selected from the group consisting of a fatty ester, fatty alcohol, fatty amide, and combinations thereof.

摘要： Disclosed are processes for tinting hydrogel materials, such as contact lenses, by dissolving a leuco sulfate ester of a vat dye in a compatible monomer solution, adding an oxidizing initiator to the monomer solution, and oxidizing and polymerizing the monomer solution and dye in the same solution. In one aspect, the oxidation and polymerization are conducted simultaneously whereas in another embodiment, the oxidation of the soluble leuco sulfate ester of a vat dye to the insoluble vat dye and polymerization are conducted sequentially in the same reaction medium.

摘要： This invention relates to a new pigment in feed for salmonids, a new feed comprising this pigment and use of this pigment. The pigment comprises a diester of predominantly (3R,3'R)-astaxanthin, cantaxanthin or other carotenoids that can be used for pigmentation of salmonids prepared with an omega-3 fatty acid and/or a shortchain corboxylic acid. By this invention a pigment for feed to salmonids that is more or as stable as, and biologically more effective than free astaxanthin and previously known diesters of astaxanthin and commercially available astaxanthin and cantaxanthin products, is provided. The said diesters are also useful for enhancing the growth of farmed fish, as a growth-enhancing agent in feed for farmed fish, as an appetizer in feed for fish as well as for increasing the utilization of the feed for farmed fish, and foroptimising health and well-being of farmed fish.

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。
