| 摘 要： | 本工作测定了油溶性内偶成色剂形成的染料影像的遮盖效率和吸收光谱,并研究了染料影像的遮盖效率和密度之间的关系,发现遮盖效率随密度的增大而减小,吸收谱带随密度的增大而变宽。这些结果同Gledhill和Julian的理论是相符的。实验结果表明,成色剂的分散度对染料影像的吸收谱带有一些影响,而对遮盖效率几乎没有影响。

| Abstract: | The covering power efficiency (CPE) of dye images formed by substantive hydrophobic color couplers was determined and the light absorption characteristics of the dye images were investigated. It was found that the CPE decreases with increasing optical density and the absorption bands were broader at higher densities. These are in accordance with the theory of Gledhill and Julian. It was also found that the dis-persity of the color coupler has some influence on the absorption bands of the images, whereas it has practically no effect on the CPE of the dye images. |
