DIR成色剂是一种在显影过程中能够释放出抑制物质的成色剂。 DIR成色剂既适用于制造一般静像摄影用的27DIN彩底,也能显著降低电影彩底的颗粒度,提高解像力和彩色还原的质量。本文扼要介绍DIR成色剂在改善彩底照相性能方面的复杂机理。
DIR couplers are couplers that release inhibitory substances during development. The DIR coupler is suitable for both the 27DIN color base for general still photography and the grain size of the movie color base, improving the resolution and color reproduction quality. This article summarizes the complex mechanism of DIR couplers in improving the performance of color-based photography.
