An electrically activatable recording material and a method of recording an image using the material. The material comprises an electrically conductive support having thereon, in sequence: (a) a polymeric electrically active conductive (EAC) layer, (b) an electrically activatable recording layer comprising (A) a dye-forming coupler, and (B) an oxidation-reduction combination comprising (i) an organic silver salt oxidizing agent, such as a silver salt of a 1,2,4-mercaptotriazole derivative, with (ii) a reducing agent which, in its oxidized form, forms a dye with the dye-forming coupler, and, preferably, (c) a photoconductive layer separated from (b) by an air gap of up to 20 microns, and (d) an electrically conductive layer; wherein the polymeric EAC layer (a) comprises a halogen containing polyester,such as poly [2,2'-oxydiethylene:2,2'-dimethyl-1,3-propylene (50:50) 2,5-dibromoterephthalate] and poly[ethylene:2,2-dimethyl-1,3-propylene (50:50)2,5-dibromoterephthalate]. The recording material is room light handleable and provides a dye image and silver image by dry development processing.
一种可电激活的记录材料和一种使用该材料记录图像的方法。该材料包括一个导电支架,其上依次有(a) 聚合物电活性导电层 (EAC),(b) 电活化记录层,包括 (A) 形成染料的耦合剂,和 (B) 氧化还原组合,包括 (i) 有机银盐氧化剂,如 1、2,4-巯基三唑衍生物的银盐,以及(ii)还原剂,还原剂以其氧化形式与染料形成耦合剂形成染料,以及,优选地,(c)与(b)之间由最多 20 微米的气隙隔开的光电导层,以及(d)导电层;其中聚合物 EAC 层(a)包括含卤聚酯,如聚[2,2'-氧二乙烯:2,5-二溴对苯二甲酸乙二醇酯]和聚[乙烯:2,2-二甲基-1,3-丙烯(50:50)2,5-二溴对苯二甲酸乙二醇酯]。这种记录材料可在室光下使用,通过干显影处理可获得染料图像和银图像。
