Abstract
A coloring composition having excellent light fastness, color migration properties, and flatness, a colorant, and a method for producing a colorant are provided. Further, a cured film, a color filter, a method for manufacturing a color filter, a solid-state imaging device, an image display device, and an organic electroluminescent element, each using such the coloring composition, are also provided. The coloring composition contains a colorant represented by General Formula (1) and a curable compound, and has a specific absorbance of 5 or more at a maximum absorption wavelength of 400 nm to 800 nm. R1 represents an (m+n)-valent linking group, P represents a monovalent substituent having a repeating units derived from a vinyl compound, D represents a colorant structure, and R2 and L1 each independently represent a single bond or a divalent linking group.
