Abstract

Es werden ein druckempfindliches Aufzeichnungsblatt und eine Beschichtungsmasse für ein derartiges Aufzeichnungs­ blatt beschrieben, wobei die Beschichtungsmasse Mikro­ kapseln A, die einen farblosen Farbstoff in einem Lösungs­ mittel S₁ gelöst enthalten, und Mikrokapseln B, die ein den Farbstoff nicht-lösendes, farbstoffreies Lösungsmittel S₂ enthalten, umfaßt. There will be a pressure sensitive recording sheet and a coating composition for such a recording sheet described, the coating composition micro capsule A, which is a colorless dye in a solution medium S₁ dissolved contained, and microcapsules B, the the dye non-solvent, dye-free solvent S₂ included.

Das erfindungsgemäße druckempfindliche Aufzeichnungsblatt ist bezüglich der durch thermische Einwirkungen hervorge­ rufenen Verschmutzung verbessert, ohne daß die Bilddichte erniedrigt wird. The pressure sensitive recording sheet of the present invention is concerned with thermal effects called pollution improves without reducing the image density is lowered.
