我们与上海冠龙照相材料商店加工组合作,经过多次试验后,采用一种溴化钾较低的配方,发现了东方软片显影的时间必需延长,这样冲洗的软片(曝光条件降至比“AGFA”快速片还低)对比及清晰度显著提高。并可与进口片相此现将我院所采用之显影配方介绍如下:米吐儿(Metol) 40克几奴尼(HOG_6H_4OH) 165克无水炭酸钠(Na_2CO_3) 800克无水亚硫酸钠(Na_2 SO_3)1150克溴化钾(KBr) 35克
We and Shanghai Guanlong photographic materials processing shop team, after many tests, the use of a lower potassium bromide formula and found that the Eastern film development time must be extended, so flush the film (exposure conditions dropped to more than “AGFA” fast films are still low) contrast and sharpness improved significantly. And with the imported film phase I now used in the Institute of the development formula are as follows: Metol 40 grams of Chinook (HOG_6H_4OH) 165 grams of anhydrous sodium carbonate (Na_2CO_3) 800 grams of anhydrous sodium sulfite (Na_2SO_3 ) 1150 grams of potassium bromide (KBr) 35 grams
