Document Type and Number:
WIPO Patent Application WO/2022/107601
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: an inkjet ink composition which contains semiconductor nanocrystals composed of a metal halide and from which a cured film having excellent light resistance at a high temperature can be formed; and a light-converting layer and a color filter which use said ink composition. The problem can be solved by an inkjet ink composition according to the present invention, the ink composition comprising: light-emitting particles including semiconductor nanocrystal particles composed of a metal halide; a photopolymerizable compound; a photopolymerization initiator; and an NOR-type hindered amine compound having a structure represented by formula (1). [In formula (1), R1-R5 each independently represent a hydrocarbon group, and * represents a dangling bond.]
