摘要：
New para-phenylenediamines suitable for use in the oxidative dyeing of hair are described which provide useful "background" green shades. These compounds have the formula: ##STR1## in which n is an integer from 2 to 6 and R denotes an unsubstituted or mono- or poly-hydroxy substituted linear or branched alkylene group containing up to 6 carbon atoms, which alkylene group can optionally contain one or more ether groups.
