银盐感光材料的感光度与解象力一般成反比.近年来关于乳剂技术的进步,感光度与解象力的关系发生了变化,提高胶片的感光度,几乎不降低解象力.对于彩色胶片,支配解象力的因素是银盐颗粒周围的成色剂结构.发明DIR成色剂以后,如果成色剂结构已经接近银颗粒直径,解象力的界限不可避免地受颗粒直径的支配.黑白感光材料,同样可以根据颗粒性设想解象力与感光度的关系.
The sensitivities of silver salt photographic materials are generally inversely proportional to the resolution of the solution.In recent years on the progress of the emulsion technology, the relationship between the sensitivity and the solution of the imaginative changes to improve the sensitivity of the film, almost without reducing the resolution .For color film, the factors that dominate the resolution Is the coupler structure around the silver salt particles.After the invention of the DIR coupler, if the coupler structure is close to the silver particle diameter, the boundary of the force of resolution is inevitably dominated by the particle diameter.Black and white light-sensitive materials, the same can be based on the particle imagination and Sensitivity of the relationship.
