几年前,吉伐公司曾生产过985型吉伐彩色正片。这种胶片的加工是以含有2-氨基-5-二乙氨基甲苯单分子盐酸盐(CD-2)彩色显影剂为主剂的显影液加工的。1974年,吉伐公司又生产了一种改进的986型彩色正片。这一胶片保持了985型胶片的彩色饱和度、锐度和感光度等性能。其中最重要的一点是,改进了胶片的颗粒性,因而它可以适应各方面的要求,特别是适用于窄胶片上。 A few years ago, JV Company produced 988 type JV color positives. The film is processed with a developer containing a 2-amino-5-diethylaminotoluene monohydrochloride (CD-2) color developing agent as the main agent. In 1974, JV also produced an improved 986 color positive. This film retains the 985 film color saturation, sharpness and sensitivity and other properties. The most important point is to improve the granularity of the film, so that it can adapt to all aspects of the requirements, especially for narrow film.
