Styryl-based coloring matter for heat-sensitive transfer recording

Abstract

Abstract NEW MATERIAL:A compound of formula I (X is OH, cyano or chlorine; R is aryl, methyl, ethyl, propyl or butyl). EXAMPLE:3-methyl-4-(beta',beta'-dicyanovinyl)-N-(beta'-hydroxyethyl)-N -methylaniline. USE:Yellow-colored titled matter capable of sublimation; which is capable of transfer recording with adequate color concentration without heavy loading on heat-sensitive recording head because of large molecular extinction. Suitable for obtaining full-color by the combination with fuchsine and cyan coloring matters. PREPARATION:An aniline of formula II is made to react, in DMF, with phosphorus oxychloride to form an aldehyde of formula III, which is then made to react with malonitrile.
