    摘要: A fluorescent particle includes a fluorescent pigment, such as a trans-dicarboxylic-indenofluorenone, and at least one stabilizing wax chemically attached to the fluorescent pigment. The stabilizing wax includes an amine group at its terminal end and the fluorescent pigment includes at least one carboxylic acid group, where the amine group reacts with the carboxylic acid group to form an amide bond. A method for making fluorescent particles for use in toners by chemically attaching at least one stabilizing wax to a fluorescent pigment where the at least one stabilizing wax includes an amine group at its terminal end and the fluorescent pigment includes at least one carboxylic acid group. A toner may include a resin and the fluorescent particle.

    摘要: The present disclosure provides processes for producing images of excellent color fidelity when incorporating a magenta toner with a lower colorant loading in addition to a first magenta toner. In embodiments, the magenta pigmented particles may be magenta emulsion aggregation toners. In accordance with the present disclosure, a pair of magenta toners are matched in color, wherein the color of a first magenta toner printed at a predetermined halftone area coverage on a substrate substantially matches the color of the solid (100%) printed patch of the second magenta toner, which is lighter than the first magenta toner, thus avoiding a visible hue shift on the print that would otherwise be objectionable. In embodiments, the light magenta toner is color matched by adding a hue-adjusting colorant or combination of colorants which absorb wavelengths of light between 400 and 500 nanometers, and optionally adding a shade-adjusting colorant or combination of colorants which absorb wavelengths of light between 600 and 700 nanometers.

    摘要翻译: 本公开提供除了第一品红色调色剂之外,当掺入具有较低着色剂负载的品红色调色剂时,还提供了用于产生具有优异色彩保真度的图像的方法。 在实施方案中,品红色着色颗粒可以是洋红色乳液聚集调色剂。 根据本公开,一对品红色调色剂的颜色相匹配,其中印刷在基板上的预定半色调区域覆盖的第一品红色调色剂的颜色基本上与固体(100%)印刷贴片的颜色匹配 第二品红色调色剂比第一品红色调色剂轻,从而避免了印刷品上可见的色调偏移,否则会令人反感。 在实施方案中,通过添加色调调节着色剂或吸收400至500纳米之间的光的波长的着色剂的组合,并且可选地添加调色剂或着色剂的组合,所述着色剂吸收波长的光 600和700纳米。
