Abstract
The invention provides a composition of matter used to produce very soft high grades of tissue paper. The composition of matter comprises a PAE resin acidified with a multifunctional acid. The multifunctional acid includes but is not limited to carboxyl and sulfonyl. The acid has a functional group selected from carboxyl and sulfonyl and a functional group selected from carboxyl, sulfonyl, hydroxyl, lactone, phenol, amine and heterocycle. The PAE resin facilitates the use of an adhesive in a Yankee Dryer apparatus that is durable when the adhesive is wet but remains soft when the adhesive becomes dry. These properties allow the adhesive to be strong and remain engaged to the dryer apparatus when wet but be easily removed by the creping blade when dry.
