加工药剂(药包)为一步摄影(波拉法)感光材料三个组成部分中具有关键影响的一部分。一步摄影利用银盐扩散转移原理,其最大特点是加工迅速,使用方便。黑白片一般在10秒中内即可加工完毕,得到正像。即便是通常繁琐的彩色加工,波拉片也要求在一分钟之内加工完毕。这就对显影剂有严格的要求。国内以往试制的的波拉片显影剂,大多采用菲尼酮——对苯二酚体系
Processing agents (kits) are part of a key impact in the three components of one-step photographic (Polafa) photographic materials. One-step photography using the principle of diffusion and transfer of silver salts, the most prominent feature is the rapid processing, easy to use. Black and white film generally within 10 seconds can be processed within, get just like. Even the usual cumbersome color processing, Polaroid also requires processing within one minute is completed. This has strict requirements on the developer. Polaroid domestic previous trial of the developer, most of the use of phenone - hydroquinone system
