Title:
ELECTROMAGNETIC WAVE SHIELDING LIGHT TRANSMITTING WINDOW MATERIAL AND DISPLAY UNIT
Document Type and Number:
WIPO Patent Application WO/2001/044840
Kind Code:
A1
Abstract:
An electromagnetic wave shielding light transmitting window material which is light-weight, thin, hard to crack and scatter even if cracks, has a good electromagnetic wave shielding performance and near infrared cutting performance suitably used for a PDP electromagnetic wave shielding filter or the like, and can provide a light-transmitting, clear image, and which is further excellent in heat-resisting, moisture-resisting and ultraviolet-resisting near infrared cutting performance. This window material comprises one sheet of transparent substrate (2), a anti-reflection film (8), a conductive mesh (3) and a near infrared cutting film (5) that are integrated together by adhesive intermediate films (4A, 4B) and an adhesive agent (4C). The near infrared cutting film (5) comprises a near infrared cutting layer formed on the surface of a base film, and the near infrared cutting layer contains a near infrared absorbing agent consisting of a dimonium compound and a copper antioxidant such as 1,2-benzenethiol copper complex compound.
