摘要：
The present invention provides a paper sizing composition comprising a rosin material and cationic acrylamide and/or methacrylamide polymers having hydrophobic groups wherein said rosin material is directly emulsified in water with said polymers. The sizing composition has an improved storage stability and exhibits an excellent sizing performance in the acidic through neutral pH range.
