More Information
Summary:To provide a near-infrared absorption dye that can yield an absorption layer having a high visible light transmittance while having a good near-infrared shield property, and having an excellent adhesion to the abutting layer, and, furthermore, having an excellent light resistance.SOLUTION: A near-infrared absorption dye characterized by containing a squarylium-based dye having a benzene ring and a condensed ring structure containing a nitrogen atom as a constituent atom of the ring bonded to both sides of the squarylium skeleton and having an urethane structure at the 2-position of the benzene ring.SELECTED DRAWING: None 【課題】良好な近赤外線遮蔽特性を有しながら可視光透過率を高め、かつ当接する層との密着性に優れ、さらに耐光性に優れる吸収層を提供し得る近赤外線吸収色素を提供すること。【解決手段】スクアリリウム骨格の両側にベンゼン環と環の構成原子として窒素原子を含む縮合環構造が結合し、ベンゼン環の２位にウレタン構造を有するスクアリリウム系色素を含むことを特徴とする近赤外線吸収色素。【選択図】なし
