品、青成色剂的回顾与展望

A summary and prospect on magenta and cyan dyes couplers

本文扼要概述了近几年来国外在研究开发新型的品红和青成色剂的进展。在品红成色剂方面着重指出吡唑并三氮唑类化合物具有:染料有害吸收少,耐光性好等优点,因此已被国外一些著名大感光材料公司应用于彩色胶片和相纸的实际生产中,为提高青染料的牢度,已开发一些取得实际应用效果的青成色剂.如:含新取代基的苯酚系和萘酚系青色剂等。作者预示了这两类成色剂的发展前景。

This paper offers a brief summary of advancements on the research of new types of magenta arid cyan dyes couplers in recent years abroad. The author emphasized that pyrazolotri-azol type magenta dyes couplers have a series of advantages, e.g.low parasitic light absorption, high light stability ect, , thus are already used by world leading photo-manufacturers for making color film and color papers. Aimed at improving the color durability of cyan dyes, new type of cyan couplers are already developed and put into practical use with substantial effectiveness, e. g. new sustituted phenol and naphtol categories cyan couplers etc.. The author predicted the prospect of development of these two kinds of color couplers.
