Document Type and Number:
Japanese Patent JP2017053979
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a blue colored composition for a color filter excellent in high lightness, a high contrast ratio and heat resistance, and a color filter excellent in high lightness, a high contrast ratio and heat resistance using the above composition.SOLUTION: A colored composition for a color filter is provided, comprising a colorant (A), a binder resin (B) and an organic solvent (C). The colorant (A) comprises: a resin salt-forming compound (A1) obtained by allowing a vinyl resin (a1) having a structural unit having a cationic group in a side chain and represented by general formula (1) to react with an anionic dye (a2); and a colorant (A2) that is a colorant (A2-1) represented by general formula (2) or a colorant (A2-2) represented by general formula (3), having a peak wavelength λmax2 in a longer wavelength side by 5 to 100 nm than a peak wavelength λmax1 of the resin salt-forming compound (A1).SELECTED DRAWING: None
