Abstract

212,484. Akt.-Ges. f³r Anilin-Fabrikation. March 9, 1923, [Convention date]. Films; preventing halation; retouching. - A hydrophil colloid layer, coated on the back of a film to prevent halation and curling, has finelydivided substances embedded in it to give it a surface suitable for retouching. The colloid may be gelatine, albumen, or casein, and the embedded substance milk, rice starch, or compounds of the alkaline earths or heavy metals. Dyes such as acid fuchsine or aurin, or other substances for preventing halation, may be added to the coating composition.
