Near-infrared ray absorbing composition, curable composition, cured film, near-infrared ray cutting filter, solid-state image capturing element, infrared sensor, camera module, processing pigment and process dye production method

摘要

The invention provides a near-infrared absorption composition having high dispersibility of a near-infrared absorption coloring agent and small thixotropy, a curable composition, a cured film, a near-infrared cut filter, a solid-state imaging device, an infrared sensor, a camera module, a processed coloring agent, and a method of manufacturing a processed coloring agent. The near-infrared absorption composition according to the invention includes a processed coloring agent obtained by coating a near-infrared absorption coloring agent with a resin having one or more selected from a coloring agent structure, a heterocyclic structure, and an acyclic hetero atom-containing group. The near-infrared absorption coloring agent is preferably one or more selected from a phthalocyanine coloring agent, a perylene coloring agent, a pyrrolopyrrole coloring agent, a cyanine coloring agent, a dithiol metal complex coloring agent, a naphthoquinone coloring agent, a diimmonium coloring agent, an azo coloring agent, and a squarylium coloring agent and more preferably a pyrrolopyrrole coloring agent.
