Abstract (en)
[origin: US4379721A] The present invention relates to a pressure-sensitive recording material having improved storability, lightfastness and heat resistance, which comprises a unit containing a dye precursor or its solution and a unit containing a dye acceptor material which is capable of color formation by reaction with the dye precursor. The pressure-sensitive recording material according to the invention is characterized in that the dye acceptor material is an intimate mixture comprising (a) a 2-hydroxy-benzophenone of the general formula I <IMAGE> or 3,5,7,3',4'-pentahydroxy-flavone of the formula II <IMAGE> (b) a substituted benzotriazole of the general formula III <IMAGE> and, optionally, an inert waxy binder. The invention further relates to further embodiments of this recording material with improved properties as well as process for producing the pressure-sensitive recording materials according to the invention.
