本迁移元件由一块衬底(22)、一层包含可软化材料的可软化膜层(26)和一种对红外辐射或红光灵敏的颜料(24)组成。可软化膜层中不包含电荷输运材料。与衬底隔开的可软件化膜层的表面上或表面附近含有一种迁移标示材料(28),该迁移标示材料对一种波长上的辐射灵敏,而对颜料(24)所敏感的红外辐射或红光不灵敏。这种成象元件的优点是。减少了曝光时间,增加了成象前的电荷寿命,而且所需红外或红光
The migration element consists of a substrate (22), a layer of softener film (26) comprising a softener material and a pigment (24) sensitive to infrared radiation or red light. The softening film does not contain charge transport materials. A software label layer (28) is included on or near the surface of the layer of softwareable film spaced from the substrate, the label material being sensitive to radiation at one wavelength and the infrared (IR) sensitive to pigment (24) Radiation or red light insensitive. The advantage of this imaging element is. Reduce the exposure time, increase the life of the image before the charge, and the required infrared or red light
