| titleOfInvention | Pressure sensitive recording materials |
| abstract | ABSTRACT 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 or 3,5,7,3',4' -pentahydroxy-flavone of the formula II b) a substituted benzotriazole of the general formula III 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. |
