<p>The electrophoretic formation of images, using two electrodes and finely divided dyestuff, takes place using a finely divided suspension of a compound of formula X-N=N-Y where X and Y are substd. or unsubstd. aromatic or heterocyclic groups, and salts and mixtures thereof. Examples of pigments are 1-(1'-naphthylazo)-2-naphthol and 3-methyl-1-phenyl-4-(3'pyrenylazo)-2-pyrazolin-5-one.</p> |
