In addition to high light resistance and high heat resistance, we have achieved high solubility in various solvents.
At Yamada Chemical Industries Co., Ltd., we offer a wide range of materials that selectively absorb specific light in the near-infrared region. In addition to high light resistance and high heat resistance, we have achieved high solubility in various solvents. Utilizing these features, we can process not only through coating but also by blending into resins. We can also achieve high transparency with a high transmittance in the visible region. Leveraging the selective absorption properties, our materials are gaining attention for new applications such as heat-shielding materials and anti-counterfeiting inks. We provide materials tailored to various needs, including high durability (light resistance, heat resistance), high transmittance, and high solubility. 【Features】 ○ FDN Series: Absorbing dyes for 750-1000nm → We offer a variety of functional phthalocyanines (naphthalocyanines) that function as near-infrared absorbing dyes. → In addition to high light resistance and heat resistance, molecular design has made them easier to dissolve in various solvents.
