Abstract: Potassium iodide (or a related iodide) when incorporated in an alkaline activator for use in a rapid access processor using developer-incorporated, resin-coated paper, (i) produces a cold image tone in black-and-white photographic prints, and (ii) maintains the image tone of a large number of prints within a narrow image tone range over a (one week or one thousand 8.times.10 inch print) design life of the activator solution.
Abstract translation: 碘化钾（或相关的碘化物）当掺入碱性活化剂中用于快速接触处理器时，使用显影剂掺入的树脂涂布纸，（i）在黑白照相印刷品中产生冷色调色调，和 ii）在激活剂溶液的（一周或一千8×10英寸打印）设计寿命内，在狭窄的图像色调范围内保持大量印刷品的图像色调。
