Abstract
A blue curable resin composition includes a colorant (A), a resin (B), a polymerizable compound (C) and a polymerization initiator (D). The colorant (A) includes two or more pigments each having a phthalocyanine backbone. The blue curable resin composition has relatively low in Bx and is high in intensity in an xy chromaticity diagram of an XYZ color system. A color filter may be formed from the blue curable resin composition. The blue curable composition may be also used in a display device.
Claims4
A blue curable resin composition comprising a colorant (A), a resin (B), a polymerizable compound (C) and a polymerization initiator (D), wherein
- the colorant (A) comprises two or more pigments each having a phthalocyanine backbone,
- the two or more pigments each having the phthalocyanine backbone comprise (a) C.I. Pigment Blue 15, and (b) a pigment selected from the group consisting of C.I. Pigment Blue 15:4 and C.I. Pigment Blue 16,
- wherein the content ratio of (a) C.I. Pigment Blue 15 and (b) a pigment selected from the group consisting of C.I. Pigment Blue 15:4 and C.I. Pigment Blue 16 (C.I. Pigment Blue 15/a pigment selected from the group consisting of C.I. Pigment Blue 15:4 and C.I. Pigment Blue 16) is 0.01 to 20 on a mass basis.
A blue curable resin composition comprising a colorant (A), a resin (B), a polymerizable compound (C) and a polymerization initiator (D), wherein
- the colorant (A) consists of two or more pigments each having a phthalocyanine backbone so that the two or more pigments each having a phthalocyanine backbone are the only pigments in the composition, and the two or more pigments each having the phthalocyanine backbone comprise (a) C.I. Pigment Blue 15, and (b) a pigment selected from the group consisting of C.I. Pigment Blue 15:4 and C.I. Pigment Blue 16.
