Document Type and Number:
WIPO Patent Application WO/2021/054248
Kind Code:
A1
Abstract:
Provided is a coloring composition comprising: a colorant including a red colorant; a resin; a polymerizable compound; and a photopolymerization initiator. The resin includes a resin BI having a repeating unit containing a blocked isocyanate group. The coloring composition has an Amax1/Amin1 of at least 25, which is the ratio of the maximum absorbance Amax1 for light having a wavelength of 400-500 nm to the minimum absorbance Amin1 for light having a wavelength of 550-700 nm. When the absorbance for light having a wavelength of 500 nm is 1, the wavelength at which the absorbance is 0.3 is in a range of 570-620 nm. A cured film obtained by curing the coloring composition; and a color filter and a display device comprising the cured film are also provided.
