Title:
PIGMENT COMPOSITION FOR COLOR FILTERS, AND COLOR FILTER
Document Type and Number:
WIPO Patent Application WO/2018/043548
Kind Code:
A1
Abstract:
Provided are: a novel pigment composition for color filters, which is capable of forming a color filter having high luminance; and a color filter which contains this pigment composition for color filters. This pigment composition for color filters contains a green pigment that has such spectral characteristics that the transmittance at the wavelength of 555 nm is 45% or more, the ratio of the transmittance at the wavelength of 505 nm to the transmittance at the wavelength of 555 nm, namely T(505 nm)/T(555 nm) is 1.40 or more, and the half-value width is 80 nm or less, if formed into a coating film wherein the spectral transmittance at the maximum transmission wavelength is 80%. A color filter according to the present invention contains this pigment composition for color filters.
