Abstract:

To provide a Yankee dryer coating agent capable of forming a uniform adhesive film of high tackiness on a low-tackiness coating film, in view of the fact that such capability has been highly desired in the creping step of producing sanitary paper.

The Yankee dryer coating agent contains, as the active ingredient, such a polyamide-polyamine-epichlorohydrin resin that, the reaction molar ratio of epichlorohydrin to the secondary amino groups of a polyamide-polyamine falls within a specific range, and, after the epichlorohydrin is reacted, the reaction molar ratio of a polybasic inorganic acid to unreacted secondary amino groups falls within a specific range in the resin.
