摘　　要：本文研究了在银盐直接热成像层材料中,还原剂、调色剂的结构和使用条件对成像性能和影像色调的影响趋势,筛选出了优选的化学结构及其理想应用条件,在理想条件下,试验样片最大密度达3.78,密度1.0的部位,色调a值最低可达-2.13,色调b值最低可达-2.17,为银盐直接热成像信息记录材料的研制奠定了配方基础。we studied the impact of the reducing and toning agent to the direct thermal imaging,comprising their structure and dosage, and got the dosage of the reducing and toning agent when the sample showed good performance and tone. At the most preference sample ,the Dmax of the sample could be up to 3.78, in the part that the density was 1.0,the tone of A could reach -2.13,and the tone of B could reach -2.17.
