NEAR INFRARED RAY ABSORBING MATERIAL

摘要

PURPOSE: To provide a near infrared ray absorbing material with which an image is made to be distinct and which is at the same time, excellent in weatherability and durability by solving a problem on the conventional technology and selectively absorbing only orange rays (in the region of 550-620 nm) which makes the image indistinct as well as near infrared rays absorption and hardly absorbing rays in other visible light region. CONSTITUTION: The near infrared ray absorbing material of the present invention is characterized by forming a transparent resin coating containing at least a near infrared ray absorbing coloring matter and a coloring matter selectively absorbing rays of 550-620 nm on a transparent base or by forming at least the transparent resin coating containing the near infrared ray absorbing coloring matter and a pressure-sensitive adhesive layer containing a coloring matter selectively absorbing the rays of 550-620 nm on the transparent base so as to make the pressure-sensitive adhesive layer to be the outermost layer.
