摘　　要：彩色负片的高温快速冲洗工艺C—41的标准时间是30分,新的彩色冲洗工艺RAC-41缩短到10分钟左右,尤其适用于冲洗非专业性的、一般业余照相,这种大幅度缩短彩色冲洗工艺时间是由于采用一系列新技术,如采用新的漂白液和漂白加速剂、取消了漂白和定影之间的水洗、使用新型定影液、在定影液中加入了尿素作为定影促进剂、用超级稳定液代替最后水洗等等,本文对此详加解释。The overall hi-temperature rapid processing time of C-41 process for color negative film normally is 30 minutes;it is reduced to ca.10 minutes in the new RA C-41 process which is especialIy suitable for non-professional and amateur photography.The significant shortening of processing time is based on the use of a series of new technologies e.g.the use of new bleaching agent and bleach accelerator in the bleaching bath,the use of new fixing bath containing urea as fixing accelerator,the use of super stabilizing bath and the elimination of the intermediate and final washing etc.This paper expatiates on these new technologies used.
