Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a paper particle-antisticking agent for a water doctor for a press roll and to provide a method for the antisticking of paper particles, capable of efficiently preventing paper particle from sticking to the press roll and a drying roll in the papermaking process for various kinds of paper and paperboard. SOLUTION: This paper particle-antisticking agent for a water doctor in a press roll contains a cationic polymer having the colloidal equivalent value >=3 meq/g. The method for the antisticking of paper particles is to add a cationic polymer having the colloidal equivalent value >=3 meq/g to the water doctor for the press roll of a papermaking machine in such a way that the quantity added becomes 0.001-50 g/min per 1 m of the width of the press roll.
