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.
近红外吸收组合物包括一种经过加工的着色剂,该着色剂是通过将一种近红外吸收着色剂涂覆在一种具有选自着色剂结构、杂环结构和含无环杂原子基团中的一种或多种的树脂上而得到的。近红外吸收着色剂最好是选自酞菁着色剂、过烯着色剂、吡咯啉着色剂、氰基着色剂、二硫醇金属络合物着色剂、萘醌着色剂、二铵着色剂、偶氮着色剂和鳞片着色剂中的一种或多种,更优选吡咯啉着色剂。
