NEW MATERIAL:A compound expressed by formula I [X is H, (substituted) alkyl, formylamino, (substituted) alkylcarbonylamino, benzoylamino, (substituted) alkoxycarbonylamino or halogen; Y is H, (substituted) alkyl, (substituted) alkoxy or halogen) R, R<1> and R<2> are (substituted) alkyl, allyl or (substituted) aryl]. EXAMPLE:A compound expressed by formula II. USE:A transfer sheet for sublimation type heat-sensitive transfer recording. PREPARATION:A 2-amino-4,6-dichloro-5-methylphenol expressed by formula III is reacted with chloroformic acid esters expressed by the formula ClCOOR in an inert solvent in the presence of a deacidifying agent to produce a compound expressed by formula IV, which is then reacted with p-phenylenediamines expressed by formula V in the presence of an oxidizing agent in an inert solvent. |
