DEVELOPING SOLUTION FOR PHOTOSENSITIVE PRINT PAPER

摘要

The color-developing liquid is composed of a mixture of triethanolamine and diethylene glycol in the volume ratio of 3:1-2:1 (or 0.5-2.0 vol% triethanolamine alone), 0.1-0.5 g/l organic accelerating agent, 0.2-0.3 g/l BLANKO-PHOR, and 1-4 g/l potassium salt of ethylenediamine tetraacetic acid. The produced color developer can give high contrast with color balance and permit a wide range of light exposure, and it also can reduce the amount of additive for developing to minimum and give uniform color image.
