摘要：
X-ray intensifying screens which provide reduced mottle and noise, and improved image sharpness in photographic films associated therewith are produced by including small amounts of UV light absorbers in either the underlayer, an active layer containing a phosphor exhibiting narrow or line band emission, or the overcoat layer of the overall screen structure.
