Provided are a curable coloring composition which is suitable for the production of a cured film in cyan color, having good moisture resistance, a color filter, an image sensor, and a method for producing a cured film. The curable coloring composition includes a coloring agent including a phthalocyanine pigment having Al as a central metal, a basic pigment derivative, and a curable compound, in which the coloring agent includes 80% by mass or more of the phthalocyanine pigments, and the content of the phthalocyanine pigment having Al as a central metal among the phthalocyanine pigments is 30% by mass or more.

Curable coloring composition, color filter, solid-state imaging device, image display device, and method for producing cured film

Provided are a coloring composition capable of producing a film having fewer defects generated, and the like even in a case where the coloring composition is stored for a long period of time in an environment with variations in temperature, a color filter, a pattern forming method, a solid-state imaging device, and an image display device. The coloring composition includes a heterocycle-containing coloring agent such as a compound represented by Formula (1), a phthalimide compound, a solvent, and a resin. In Formula (1), Rto Reach independently represent a hydrogen atom or a substituent, and adjacent groups of Rto Rmay be bonded to each other to form a ring, provided that at least one of the pairs of adjacent two groups of Rto Ris bonded to each other to form an aromatic ring. 

Coloring composition, color filter, pattern forming method, solid-state imaging device, and image display device

Provided is a coloring composition capable of producing a cured film having suppressed color unevenness even in a case where the coloring composition is used after being stored for a long period of time. In addition, provided are a color filter, a pattern forming method, a solid-state imaging device, and an image display device. The coloring composition includes a halogenated zinc phthalocyanine pigment, a maleimide compound, a curable compound other than the maleimide compound, and a solvent, in which the molecular weight of the maleimide compound is 100 to 400, and the content of the maleimide compound is 0.08 to 0.8 parts by mass with respect to 100 parts by mass of the halogenated zinc phthalocyanine pigment.

A coloring composition includes Color Index Pigment Red 264, a graft resin having an acid group, a photopolymerizable compound, and a photopolymerization initiator.
