NEW MATERIAL:A compound of formula I (R and R' are each aryl, methyl, ethyl, propyl, or butyl). n EXAMPLE: 3-chloro-4-(β',β'-dicyanovinyl)-N,N-dimethylaniline. n USE: Yellow colored titled matter capable of sublimation; which is capable of transfer recording of 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. n 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. n COPYRIGHT: (C)1985,JPO&Japio |
