Curable components, membranes, filters, image display devices, and optical sensors

Abstract

This invention provides a curable composition comprising: a colorant including a pigment; a photopolymerization initiator; a polymerizable compound; at least one selected from compound A1, compound A2, and compound A3; and a solvent. The photopolymerization initiator comprises a glyoxylate compound. Compound A1 is at least one selected from compound A1-1, which has a base and grafted chains and a weight average molecular weight of 2000 or more and 30000 or less, and block copolymer A1-2, which has a base and a weight average molecular weight of 2000 or more and 30000 or less. Compound A2 is a compound having a pigment structure and bases and a molecular weight of 100 or more and less than 2000. Compound A3 is a polyalkylimide. This invention also provides a film, a filter, an image display device, and an optical sensor using the aforementioned curable composition.
