国际照相材料市场上400ASA高感微粒彩色底片的普及化,说明感光化学工业在理论研究和生产工艺方面都已取得了显著的进展。据了解,目前日本富士和小西六公司已开始着手研制1000ASA以上的高速彩色底片;西德和比利时的阿克发—吉伐公司说,它已找到了新的途径来缩短理论计算极限感光度和实际所能达到的感光度之间的差距。如何从低感粗粒向高感微粒发展,无疑是我国感光化学工业赶超世界先进水平所面临的一个重要课题。
The popularity of the 400ASA high-sensitivity microparticle color film on the international photographic materials market shows that the photochemical industry has made significant progress in both theoretical research and production technology. It is understood that at present Japan’s Fuji and Little West Six companies have begun to develop high-speed color film above 1000ASA; West Germany and Belgium’s Akta-Jager company said it has found a new way to reduce the theoretical limit of sensitivity and The actual sensitivity of the gap can be achieved. How to develop from low-grade coarse grains to high-sensitive grains is undoubtedly an important issue that our sensitive chemical industry has to catch up with the advanced world level.
