摘要：

Metal complexes of hydroxycarboxylic acids or dicarboxylic acids were prepared, and the protecting effect of these compounds towards the photofading of colour materials derived from colour formers was examined on cellulose. It is proposed that nickel or zinc salts of 1-hydroxy-2-naphthoic acid and its derivatives can be applied as effective stabilisers against the photofading of indicator dyes in pressure- (or heat-)sensitive recording systems. These metal carboxylates were also found to improve the image stability of the indicator dyes.
