An aqueous formulation of a high solid content fully functional thermosettable wet strength resin designed for use in the manufacture of paper products is disclosed. The wet strength resin is the product of reaction of an epihallohydrin and an end-capped polyaminamide polymer. The thermosetting wet strength resins are useful in the manufacture of improved absorbent paper products such as bathroom tissues, facial tissues, napkins, towels, and paperboard products such as dairy cartons and bag paper.

L'invention concerne une formulation aqueuse d'une résine thermodurcissable entièrement fonctionnelle à haute teneur en solide, résistant au mouillé, utilisable dans la fabrication de produits en papier. La résine résistant au mouillé est le produit de la réaction d'une épihalohydrine et d'un polymère de polyaminamide coiffé en bout de chaîne. Les résines thermodurcissables résistant au mouillé sont utilisées dans la fabrication de produits en papier absorbants améliorés, tels que tissus essuie-mains, tissus à démaquiller, serviettes de table, serviettes et produits en carton tels que cartons pour produits laitiers et papier pour sacs.
