Abstract

235,922. Rogers, A., and Mimo Corporation. Dec. 27, 1923. Ink.-Sympathetic ink for printing on newspapers &c. consists of alcohol, a thickening agent, and a sensitive ingredient such as phenolphthalein, cobalt chloride, ferrous sulphate, ferrous ammonium sulphate, or sugar. A non- inflammable substance such as carbon tetrachloride may be added to obviate risk from fire. The thickening agent may be glycerine, or a mixture of glycerine and acetone; with phenolphthalein and sugar, a mixture of resin and soap may also be used.
