Document Type and Number:
WIPO Patent Application WO/2022/034734
Kind Code:
A1
Abstract:
The present invention is to solve the problem of providing a coloring composition containing a perylene-based compound such as C.I. pigment violet 29 while achieving high dispersion into a glycol-based solvent, the coloring composition being usable in a display production process without provoking insufficient resist curing or a drop in spectral purity. This coloring composition contains the sulfonate compound represented by formula (1), and C.I. pigment violet 29. Formula (1): A-SO3M·nH2O
[In the formula (1), A represents a hydrocarbon group having 1 to 20 carbons, optionally having within the structure a halogen, a boron, a nitrogen, a sulfur, a phosphorus, or an oxygen, M represents one equivalent of a cation having a valence of 1 to 3 excluding H, and n represents an integer from 0 to 5]
