Abstract

The fading behaviors of C.I. Direct Red 81 and C.I. Direct Blue 76 on the cellophane film were examined by using their CF curves. Both of dyes showed negative slope of CF curve, and revealed anomalous fading characteristics, i. e., reduced lightfastness with increased dye concentration, a reversal of the normal trend.
