Method of Improving Odor in Electrosensitive Paper

Objectionable odors, particularly those associated with sulfur compounds which are released from metallized electrosensitive papers during printing, can be eliminated by the following techniques.

The offensive odor has been variously described as 'similar to that emitted by an electric train', sulfide or sulfite, firecracker, acetylene, and burnt. Zinc acetate will prevent the development of the above-mentioned odor. The exact mechanism of deodorization is not fully known, but the tying up of free or reducible sulfur compounds plays a major role. Zinc acetate at concentrations of one and ten percent have been found effective. Other zinc or copper salts will have a similar effect in preventing odor from developing.

Coated and metallized electrosensitive paper can be impregnated with a solution of zinc acetate and dried. It is possible to incorporate a zinc or other metallic salt into the paper and coating, thus eliminating the need for separate impregnation and drying steps.
