Abstract
Creping adhesives can include one or more crosslinked resins having the chemical formula (O), (P), or (Q), where RX can be a crosslinking moiety, each RY can independently be a substituted or unsubstituted organic diyl moiety, and each A− can independently be an anion. The creping adhesive can have a cylinder probe adhesion of about 100 gram-force to about 300 gram-force. The creping adhesive can have a peel adhesion of about 20 g/cm to about 110 g/cm.
