View Patent ↗A colored photosensitive resin composition comprising (1) an alkali-soluble binder, (2) a monomer or an oligomer, (3) a photopolymerization initiator or a photopolymerization initiator system, and (4) a coloring agent, wherein the coloring agent is a specific pigment in a specific quantity. Also provided is a color filter obtained by using the colored photosensitive resin compositions for formation of the respective photosensitive resin layers of R, G and B.
1. A colored photosensitive resin composition comprising an alkali-soluble binder, a monomer or an oligomer, a photopolymerization initiator or a photopolymerization initiator system, and a coloring agent, wherein:
the coloring agent comprises a pigment C.I.P.G.36 and a pigment C.I.P.Y.150; and
when the colored photosensitive resin composition is coated and dried to form a film with a thickness of 1 to 3 μm, a quantity of the pigment C.I.P.G.36 in the film is 0.90 to 1.34 g/m 2 and a quantity of the pigment C.I.P.Y.150 in the film is 0.38 to 0.58 g/m 2 .
2. A photosensitive resin transfer material comprising a temporary support and a photosensitive resin layer provided on the temporary support, wherein the photosensitive resin layer includes the colored photosensitive resin composition of claim 1 .
3. A method of forming a photosensitive resin layer, the method comprising adhering the photosensitive resin transfer material of claim 2 to a substrate by a laminator.
4. A method for producing a color filter, the method comprising:
forming a photosensitive resin layer;
exposing the photosensitive resin layer;
developing the photosensitive resin layer; and
baking the photosensitive resin layer,
wherein the photosensitive resin layer comprises the colored photosensitive resin composition of claim 1 .
5. A color filter produced by the method of claim 4 .
6. A liquid crystal display device using the color filter of claim 5 .
7. A coating film of a colored photosensitive resin composition, wherein:
the colored photosensitive resin composition comprises an alkali-soluble binder, a monomer or an oligomer, a photopolymerization initiator or a photopolymerization initiator system, and a coloring agent;
the coloring agent comprises a pigment C.I.P.G.36 and a pigment C.I.P.Y.150;
a content of the pigment C.I.P.G.36 in the coating film is 0.90 to 1.34 g/m 2 ; and
a content of the pigment C.I.P.Y.150 in the coating film is 0.38 to 0.58 g/m 2 .
