    Abstract: An object of the present invention is to provide a novel squarylium dye that can achieve an equivalent chromaticity value of even a colored resin composition having a low content of the squarylium dye as compared with a colored resin composition comprising a conventional squarylium dye. The present invention provides a compound represented by the formula (I) wherein R4 to R4 each independently represent a hydrogen atom or the like; R5 to R8 each independently represent a hydrogen atom or the like; R9 and R10 each independently represent a monovalent saturated hydrocarbon group having 1 to 20 carbon atoms or the like; R11 and R12 each independently represent a halogen atom or an alkyl halide group having 1 to 6 carbon atoms; and m1 and m2 each independently represent an integer of 1 to 5.

    Abstract: It is an object of the present invention to provide a negative resist composition that is useful for producing a color filter with a high transmittance of light at a wavelength of 440 nm. A negative resist composition of the present invention comprises a colorant and a resin, wherein the colorant contains a xanthene dye, and a cured film formed from the negative resist composition exhibits a spectrum that satisfies the following condition 1: [condition 1] a maximum absorption wavelength is present in a wavelength range of 500 to 580 nm, and based on a transmittance at the maximum absorption wavelength being 5%, a transmittance at a wavelength of 440 nm is 80% or more and a transmittance at a wavelength of 620 nm is 80% or more.

    Abstract: The object of the present invention is to provide a colored resin composition containing an aluminum phthalocyanine pigment capable of forming a colored coating film with no foreign matter (preferably a colored coating film with no foreign matter and good adhesion). The colored resin composition of the present invention contains a colorant, a compound represented by formula (DA), a resin, and a solvent, wherein the colorant contains an aluminum phthalocyanine pigment.




    [In formula (DA), Rd1 represents a hydrocarbon group having 1 to 12 carbon atoms and optionally having a substituent. When the hydrocarbon group has 2 to 12 carbon atoms and the hydrocarbon group has —CH2—, —CH2— may be substituted with —O—, —S—, or —CO—. Rd2 and Rd3 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 12 carbon atoms and optionally having a substituent, or Rd2 and Rd3 are combined to form a ring together with —CO—NRd1—CO—.]
