    • PROBLEM TO BE SOLVED: To provide a red or yellow photosensitive colored composition for a color filter, the composition having high luminance, capable of suppressing decrease in luminance in a formation step of a color filter, excellent in heat resistance and giving a good pattern profile of a filter segment, and to provide a color filter with high luminance and high definition using the composition.SOLUTION: The photosensitive colored composition includes a red pigment and/or a yellow pigment, and as an antioxidant (C), a phenolic antioxidant (c1), with a sulfur antioxidant or a phosphorus antioxidant (c2). Thereby, with the composition, a red or yellow filter segment having high lightness and an excellent pattern profile can be formed. Therefore, a high-quality color filter can be obtained by using the photosensitive colored composition.
    • 要解决的问题:为了提供一种用于滤色器的红色或黄色感光着色组合物,该组合物具有高亮度,能够抑制滤色器的形成步骤中的亮度降低,耐热性优异并且具有良好的图案轮廓 并且使用该组合物提供具有高亮度和高清晰度的滤色器。解决方案:感光着色组合物包含红色颜料和/或黄色颜料,作为抗氧化剂(C),酚类抗氧化剂( c1),含硫抗氧化剂或磷抗氧化剂(c2)。 因此,通过该组成,可以形成具有高亮度和优异图案轮廓的红色或黄色过滤器段。 因此,通过使用感光着色组合物可以获得高质量的滤色器。

    • PROBLEM TO BE SOLVED: To provide a color composition that allows formation of a filter segment and a black matrix having a superior cross-sectional profile even with high sensitivity by a laser exposure method at a specified wavelength, and to provide a method for manufacturing a color filter by using the composition, and a color filter manufactured by the method.
      SOLUTION: The color composition, to be used for the following method for manufacturing a color filter, contains a pigment, a transparent resin, a monomer having an ethylenically unsaturated double bond, a photopolymerization initiator and a polymerization inhibitor. The method includes steps of: forming a color coating film by using the color composition on a substrate; curing the part of the color coating film, the part to be a filter segment or a black matrix, by irradiating the part with laser light at a wavelength of 340 to 380 nm; and forming the filter segment or the black matrix by removing an uncured part of the color coating film.
