Abstract:
The near-infrared absorption composition 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.
