    • PROBLEM TO BE SOLVED: To provide a dye dispersion which does not deposit foreign matter on the formation of a coating film, is excellent in redissolubility into a solvent, and can form a colored layer excellent in heat resistance, light resistance and high in brightness, and to provide a photosensitive resin composition for color filters.SOLUTION: There are provided the dye dispersion produced by dispersing a dye (A) in a solvent (C) in the presence of a dispersing agent (B), wherein the dye (A) is a dye having a sulfonic group and/or a sulfonate salt; the dispersing agent (B) is a polymer (b2) having three or more repeating units, on the average, having a quaternary ammonium salt group in one molecular chain, produced by converting at least one portion of tertiary amines of a block polymer (b1) containing a block portion comprising tertiary amine-having repeating units into quaternary ammonium salt groups; and the solvent (C) is a solvent substantially not dissolving the dye (A); and a photosensitive resin composition using the dye dispersion.
    • 要解决的问题:为了提供在形成涂膜时不会沉积异物的染料分散体,对溶剂的再溶解性优异,并且可以形成耐热性,耐光性和高的优异的着色层 并提供用于滤色器的感光性树脂组合物。 解决方案:提供通过在分散剂(B)的存在下将染料(A)分散在溶剂(C)中制备的染料分散体,其中染料(A)是具有磺酸基的染料和 /或磺酸盐; 分散剂(B)是具有三个或更多个重复单元的聚合物(b2),平均而言,在一个分子链中具有季铵盐基团,其通过将至少一部分嵌段聚合物的叔胺(b1 ),其包含含有叔胺的重复单元的嵌段部分进入季铵盐基团; 溶剂(C)是基本上不溶解染料(A)的溶剂; 和使用该染料分散体的感光性树脂组合物。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To obtain a dye mixture suited for dip dyeing or printing a nitrogenous or hydroxyl fiber material, especially a natural or synthetic polyamide fiber material and having excellent fastness, especially excellent solubility and excellent printing paste stability by mixing two aminoanthraquinonesulfonic acids with each other. SOLUTION: This mixture comprises a dye of formula I and formula II. In formulas I and II, M s, which may be the same or different from each other, are each an ammonium cation: H-N (-R1 )(-R2 )(-R3 ) of an amine represented by formula III [wherein R1 and R2 , which are independent of each other, are each hydrogen, a 1-6C alkyl or a 2-6C alkyl which is substituted with hydroxyl or amino and interrupted by suitably oxygen; and R3 is a 2-6C alkyl which is substituted with hydroxyl or amino and interrupted by suitably oxygen]. The mixture contains a least 5wt.%, based on the total weight of the dyes of formulas I and II, dye of formula II.
