ABSTRACT:
Disclosed are cationic aqueous emulsions containing (a) sizing composition comprising the reaction product of melamine formaldehyde compound, long chain saturated alcohol and long chain saturated or unsaturated polyethoxylated alcohol; and (b) cationic surfactant. The emulsions when used to surface size paper impart improved oil, water and polar solvent resistance thereto. The emulsions may be used alone or as substantial replacements for anionic or non-ionic fluorocarbon based emulsions that are typically used to impart oil resistance to paper.
