Abstract

Lagerstabile, wäßrige Harzlösung mit einem pH-Wert von höchstens 7, enthaltend als Harz ein wasserverdünnbares Polyamidoamin-Epichlorhydrin-Harz (A), erhalten durch Umsatz eines wasserverdünnbaren, basischen Polyamidoamins (B), bestehend aus einer Säurekomponente (B₁), und einer Aminkomponente (B₂), mit Epichlorhydrin (C), wobei der Gehalt an organisch gebundenem Chlor in dem Harz (A) höchstens 4 Gew.-% beträgt und wobei die Komponente (B₂) - falls die Säurekomponente (B₁) eine aliphatische oder aromatische Carbonsäure oder deren funktionelle Derivate, gegebenenfalls in Abmischung mit einer Aminocarbonsäure oder deren Lactamen darstellt - aus einem Gemisch aus Polyaminen und Alkanolmonoaminen besteht.
Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung dieser Produkte und deren Verwendung insbesondere zur Erhöhung der Naßfestigkeit von Papier.
