Abstract
Provided is a pigment multimer whereby a pattern can be appropriately formed during formation of a pattern. Further, provided are a coloring composition using the pigment multimer; and a cured film, a color filter, a method for manufacturing a color filter, a solid-state imaging element, and an image display device, each of which uses the coloring composition. The pigment multimer (A) has a non-nucleophilic counter anion.
Claims18
