Beschreibung
Zusammenfassung:	The invention relates to a process for producing multi-layered carbonless sheets on which indicia can be xerographically produced with little or no non-specific development. The process involves coating a sheet with a CB composition containing a carboxymethyl cellulose polymer, a crosslinker, a salt of a polyvalent metal ion and a small amount of a wall forming acrylic resin. The CB coating formed resists breakage and release of dye when non-specific pressure is applied to the sheet thereby resulting in CF copies having improved brightness and reduced non-specific development.
