六十年代以来,随着感光材料在国民经济中的应用逐渐广泛深入,以及银资源的短缺,特别是一般感光材料的照相性能已不能满足科学技术发展的要求,因而推动了非银盐信息记录材料的迅速发展。它的经济价值和优异的成像性能愈来愈受到人们的重视。国际上争相研究,新的成果不断涌现,在复 Since the 1960s, as the application of photosensitive materials in the national economy has been gradually deepened and the shortage of silver resources, especially the photographic properties of general photosensitive materials, have failed to meet the requirements of scientific and technological development, they have promoted the non-silver salt information recording The rapid development of materials. Its economic value and excellent imaging performance are more and more people’s attention. International competition for research, new results continue to emerge in recovery
