Abstract

The supports are produced from a liquid dispersion of fine magnetic pigment particles in a binder which is an olefinically unsatd. polymerisable cpd. contg. 15% wt. of at least one of the gps. of formula I and/or II. CH2 = CR-CO-O- (I) CH2=CR-CO-N(R')- (II) (where R is H or CH3, and R' is H or 1-8C alkyl).
