Abstract
The effectiveness of a UV filtering material of flexible polyester film containing a silver reflective coating was compared to the widely used UV absorbing filters that are almost colorless or have a strong yellow tint. The silver-coated polyester filters caused almost no distortion of color rendition when used as a filter for fluorescent lamps and provided greater protection of artifacts than did the almost colorless mters. The use of UV filters of polyester film with a reflective silver coating is recommended when filters with a strong yellow tint distort color to an objectionable degree and yet greater protection of artifacts is desired than that afforded by almost colorless filters.
