Abstract
Provided are a coloring composition capable of producing a film having excellent light fastness, and the like, a method for producing a coloring composition, a color filter, a pattern forming method, a solid-state imaging device, and an image display device. The coloring composition includes a coated pigment in which at least a portion of a surface of a yellow pigment is coated with a resin, a halogenated phthalocyanine pigment, a dispersant having an acid value of 40 mgKOH/g or more, and a curable compound.
Claims8
A coloring composition comprising:
- a coated pigment in which at least a portion of a surface of a yellow pigment is coated with a resin;
- a halogenated phthalocyanine pigment;
- a dispersant having an acid value of 40 mgKOH/g or more;
- a curable compound;
- and
- a photopolymerization initiator which contains an oxime compound,
- wherein the yellow pigment is an azomethine-based yellow pigment which is C. I. Pigment Yellow 129,
- a surface of the halogenated phthalocyanine pigment is not coated with a resin,
- the coloring composition contains the halogenated phthalocyanine pigment in the amount of 100 to 600 parts by mass with respect to 100 parts by mass of the coated pigment,
- the acid value of the resin coating the surface of the yellow pigment is 40 to 200 mgKOH/g,
- the difference between the acid value of the resin coating the surface of the yellow pigment and the acid value of the dispersant is 100 mgKOH/g or less,
- the weight-average molecular weight of the resin coating the surface of the yellow pigment is 5,000 to 40,000, and
- the curable compound contains a trifunctional to pentadecafunctional (meth)acrylate compound.
