摘要： A colored resin composition is disclosed including a polyimide resin having a specified structure to achieve remarkable heat resistance and enabling the formation of a colored film which is excellent in reliability because a coloring material is highly dispersed and stabilized therein. A colored resin composition is disclosed including (A) an alkali-soluble polyimide resin having a structural unit containing a phenolic hydroxyl group, a sulfonic acid group or a thiol group, (B) a coloring material, (C) a polymeric dispersant, and (D) an organic solvent. A patterned colored layer obtained from the composition of the present invention is useful for a decorative substrate, a touch panel, an organic EL display device and the like.

摘要： A colored resin composition containing an alkali-soluble resin (A), a colorant (B), an organic solvent (C), and a photosensitizer (D), the colored resin composition containing at least a zirconia compound particle as the colorant (B), wherein the zirconia compound particle contains zirconium nitride having a crystallite size of 10 nm or more and 60 nm or less, and the crystallite size is determined from a half width of a peak derived from a (111) plane in an X-ray diffraction spectrum using a CuKα ray as an X-ray source. The present invention provides a highly sensitive colored resin composition by improving light transmissivity in the ultraviolet region (wavelength 365 nm) generally used in photolithography and by improving a light shielding property in the visible region.
