Coloring composition, method for producing coloring composition, color filter, pattern forming method, solid-state imaging device, and image display device
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.
1. 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.
2. The coloring composition according to claim 1 ,
wherein the halogenated phthalocyanine pigment is a halogenated zinc phthalocyanine pigment.
3. The coloring composition according to claim 1 , further comprising a pigment derivative having a basic group.
4. The coloring composition according to claim 3 ,
wherein the basic group is an amino group.
5. A color filter using the coloring composition according to claim 1 .
6. A solid-state imaging device comprising the color filter according to claim 5 .
7. An image display device comprising the color filter according to claim 5 .
8. A pattern forming method comprising:
