A radiographic element comprises a polyester support having double sided silver halide emulsion layers. An ultraviolet light absorbing methine compound is copolymerized with the support and is present in an amount sufficient to reduce the average percent transmission of ultraviolet light over the range of wavelength of from about 350 nm to about 395 nm to less than about 25 percent, and whereby the percent transmittance of said element is at least about 55 percent at a wavelength of about 410 nm for an element thickness of about 0.007 inches.
一种放射性元素包括具有双面银卤化物乳剂层的聚酯支撑。一种紫外线吸收的甲基化合物与支撑物共聚,并以足够的量存在,以使在从约350纳米到约395纳米的波长范围内的紫外线平均透射百分比降低到不到约25%,并且该元素的透射百分比在约0.007英寸的元素厚度下在约410纳米的波长处至少为约55%。
