摘　　要：本文合成了3个用于感绿X光片的防光晕染料,其吸收波长在515～550nm之间。并利用紫外、红外、高效液相色谱对其结构进行了鉴定。其中合成的不对称染料的最大吸收波长不是相应两个对称染料最大吸收波长的算数平均值,扩大了防光晕染料的选择范围。Three kinds of antihalation dye were prepared for green-sensitive X-ray film,of which the absorbency ranges from 515nm to 550nm wavelength.They were analyzed and identified by means of UV,IR,HLCP,and NMR.Difference exists between the maximum absorbency of the asymmetric dyes and the average of the maximum absorbency of the corresponding symmetric ones.As a result,the selective scope of the antihalation dyes could extend by the use of asymmetric dyes.
