TITLE: PRESSURE SENSITIVE MATERIALS ABSTRACT OF THE DISCLOSURE Pressure sensitive materials and methods of making same, wherein a layer of adhesive material is sandwiched between a printing paper sheet surface and a backing sheet surface which is preferably of high density and coated with an adhesive release agent, preferably a silicone material. The backing sheet is of undulating form with the size of the undulations being large enough to provide a high coefficient of friction with a finger engaged therewith and being small enough to minimize stretching thereof and to thereby facilitate removal and to provide substantially uniform support of the printing paper for letter press printing thereon without mottling. A barrier coating may be provided on the surface of the printing sheet which is engaged with the adhesive and a non-skid coating may be provided on the exposed surface of the backing sheet. -1-
