IR REFLECTING LAMINATE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an IR reflecting laminate which is composed of a combination of a DLC thin film and a silver-based metal film so as to reflect heat rays and allow visible light to transmit efficiently and is usable as a window material; and a DLC thin film manufacturing method which reduces light absorption of the DLC thin film in short wavelengths, prevents the thin film from being tinged with a brown color tone and allows inexpensive production with high mass productivity.SOLUTION: An IR reflecting laminate has a silver-based metal film 16 and a diamond-like carbon film having a light absorption coefficient at a wavelength of 400 nm of ≤3/μm and a thickness of 20-100 nm on a transparent substrate 14 in this order.
