摘要： The present invention relates to a colorant, a colored resin composition comprising the colorant, and a color filter prepared using the colored resin composition. A novel reddish yellow pigment may be used in combination with a green pigment and a yellow pigment in order to reduce the imbalance of the intramolecular polarization of the green pigment and/or the yellow pigment in the colorant. As a result, a color filter comprising a colored layer in which a light leakage phenomenon, caused by an electric field distortion, is reduced.

摘要： Near-infrared absorbers which contain phthalocyanine derivatives in which the four benzene rings contained in the molecule independently have 1 to 4 substituents are light and thermal resistant and possess high molar extinction coefficients. Such near-infrared absorbers are useful in optical recording media, near-infrared absorption filters, and liquid crystal display devices.
