- Coating composition comprising copper sulfide core-shell nanoparticle for selectively shielding near infrared ray

摘要

The present invention relates to a coating solution composition having a selective blocking function in the near-infrared region containing copper sulfide nanoparticles having a core-shell structure. The coating liquid composition has excellent blocking rate against infrared rays in a wide area, has excellent visible light transmittance, excellent light resistance and heat resistance of the coating film, and has excellent durability, so that the composition is applied to a base film and cured with ultraviolet rays. And it is possible to provide various glass products such as architectural glass for heat shielding and windows for automobiles using this.
