  A squarylium dye [A] that has high invisibility, i.e., exhibits low absorption in the visible light region (400 nm to 750 nm), has excellent near-infrared absorption capability and high light resistance, tends not to exhibit aggregations, and has specific X-ray diffraction peaks; and an image-forming material and the like containing the squarylium dye [A] having said characteristics. The problem is solved by a squarylium dye [A] having specific X-ray diffraction peaks represented by general formula (1). Moreover, the problem is also solved by various materials containing the squarylium dye [A].

  一种具有高隐蔽性的鳞片染料[A]，即在可见光区（400 nm 至 750 nm）吸收率低，具有优异的近红外吸收能力和高耐光性，不易聚集，并具有特定的 X 射线衍射峰；以及一种含有具有上述特性的鳞片染料[A]的图像形成材料等。具有通式（1）表示的特定 X 射线衍射峰的鳞片染料[A]解决了这一问题。此外，含有鳞片染料[A]的各种材料也解决了这一问题。
