摘要： Colorant compositions are useful for a wide variety of product applications. For example, colorants are used in tinting of polymers, providing colors to aqueous solution(s), and affording color to solid or semi-solid products such as detergents. Disclosed herein are colorant compositions having a triphenylmethane (“TPM”) structure having improved stability to alkaline conditions. Thus, the colorant compositions resist decolorization, even at relatively high pH levels.

摘要： A new and useful nonaqueous liquid pigment dispersion is provided which is easy to handle and produces thorough and effective colorations within target media, particularly as compared to standard solid pigments or high-viscosity liquid pigment dispersions. More specifically, the present invention relates to liquid pigment dispersions possessing viscosities of at most 5,000 centipoise at standard temperature and pressure. Such a low viscosity is obtained through the addition of relatively low amounts of aprotic viscosity modifiers possessing dipole moments of at between about 1.0 and 5.0, alternatively measured in terms of a flash point between about −20° C. and 180°, such as, most preferably cyclic carbonates. The resultant low-viscosity pigment compositions thus can be incorporated into any standard pigment-coloring method (such as, for example, polyurethane, polyolefin, and the like) without the problems associated with traditionally utilized solid or thickened, high viscosity pigment materials. The method of coloring such target media is also encompassed within this invention.
摘要翻译：提供了一种新的和有用的非水性液体颜料分散体，其易于处理并在目标介质中产生彻底和有效的着色，特别是与标准固体颜料或高粘度液体颜料分散体相比。更具体地，本发明涉及在标准温度和压力下具有至多5000厘泊的粘度的液体颜料分散体。通过加入相对低量的具有在约1.0和5.0之间的偶极矩的非质子传递粘度调节剂来获得这样的低粘度，或者以约-20℃和180℃之间的闪点进行测量，最优选环状碳酸酯。因此，所得到的低粘度颜料组合物可以掺入任何标准颜料着色方法（例如聚氨酯，聚烯烃等）中，而没有与传统使用的固体或增稠的高粘度颜料材料相关的问题。这种靶介质的着色方法也包括在本发明中。

摘要： A yellow colorant comprising a chromophore having at least one poly(oxy-C2-C4-alkylene) chain attached to an aromatic methine backbone having at least one cyanoester moiety attached thereto is provided. The ester portion must include a C1-C8 (such as ethyl, butyl, hexyl, or ethyl-hexyl) pendant group and the poly(oxyalkylene) chain must be at most 10 monomers and at least 3 monomers, with ethylene oxide as the capping group. Such a specific group of coloring agents provides the best overall yellow colorations or effects (either alone or in blends with other coloring agents, particularly at low color loadings) as well as the best overall low extraction levels when present within clear polyester (such as polyethylene terephthalate, for example), when compared to all other known polymeric yellow colorants for the same end-use. Compositions and articles comprising such colorants are provided as well as methods for producing such inventive colorants.

摘要： Novel ultraviolet absorbing compounds that are liquid in nature, are low in color (and thus permit use without the concomitant necessity of adding large amounts of other coloring agents to combat such discoloring), and are highly effective in providing protection in wavelength ranges for which previous attempts at low-color ultraviolet absorbers have failed are provided herein. Such compounds provide such excellent, inexpensive, and beneficial protection from ultraviolet exposure within various media, including, but not limited to, clear thermoplastics. The particular compounds are generally polymeric in nature including various chain lengths of polyoxyalkylenes thereon and are liquid in nature to facilitate handling and introduction within the target media. In addition, such ultraviolet absorbers also exhibit extremely low migratory properties thereby providing long-term protective benefits to the target media as well. This invention also concerns the end products, specific broadly defined types of compounds providing such beneficial characteristics, methods of making such low-color compounds, and methods of producing such clear, UV protected end products.
