Abstract
Provided are a resin composition including a colorant and a resin, in which the colorant contains two or more squarylium colorants represented by Formula (1) below, at least one of the squarylium colorants is a squarylium colorant having a hydrogen-bonding group, which is represented by Formula (2) below, and a colorant mixture consisting of the two or more squarylium colorants, which is included in the resin composition, has a maximum absorption wavelength in a wavelength range of 400 nm to 700 nm; an optical filter; a liquid crystal display device; a solid-state imaging element; and a colorant mixture.
Claims15
A resin composition comprising:
- a colorant;
- and
- a resin,
- wherein the colorant contains two or more squarylium colorants represented by Formula (1),
- wherein at least one of the squarylium colorants is a squarylium colorant represented by Formula (2),
- wherein a colorant mixture consisting of the two or more squarylium colorants, which is included in the resin composition, has a maximum absorption wavelength in a wavelength range of 400 nm to 700 nm,
- in Formula (1), A and B represent an aryl group, a heterocyclic group, or —CH=G, where G represents a heterocyclic group, and
- in Formula (2), A1 represents a heterocyclic group having a hydrogen-bonding group which forms an intramolecular hydrogen bond, B represents an aryl group, a heterocyclic group, or —CH=G, where G represents a heterocyclic group, and a structure of the heterocyclic group of B and a structure of the heterocyclic group of A1 are different from each other, and
- wherein the content proportion of the squarylium colorant represented by Formula (2) in the total squarylium colorants represented by Formula (1) is 70% to 99.5% by mass.
A colorant mixture comprising:
- two or more squarylium colorants represented by Formula (1),
- wherein at least one of the squarylium colorants is a squarylium colorant represented by Formula (2),
- wherein the colorant mixture has a maximum absorption wavelength in a wavelength range of 400 nm to 700 nm,
- in Formula (1), A and B represent an aryl group, a heterocyclic group, or —CH=G, where G represents a heterocyclic group, and
- in Formula (2), A1 represents a heterocyclic group having a hydrogen-bonding group which forms an intramolecular hydrogen bond, B represents an aryl group, a heterocyclic group, or —CH=G, where G represents a heterocyclic group, and a structure of the heterocyclic group of B and a structure of the heterocyclic group of A1 are different from each other, and
- wherein the content proportion of the squarylium colorant represented by Formula (2) in the total squarylium colorants represented by Formula (1) is 70% to 99.5% by mass.
