<p>A method of printing by electric coagulation of a colloid composition that is characterized by an improved colloid composition that allows very fast and accurate printing as required for computer printing and photocopying. The electrically coagulable colloid composition includes a colloid that is of reliably uniform quality and performance in combination with a salt or acid that opposes the deposition of gas bubbles against the electrodes used in that printing method. The improved colloid is selected from the group of linear colloid of high molecular weight including polyacrylic and polyacrylamid resins and polyvinylic alcohol and also from the group including casein, animal protein and vegetable protein.</p> |
