    Abstract: PROBLEM TO BE SOLVED: To provide coated base paper having a high retention and excellent blister resistance even when papermaking is carried out at a high speed under high-ash conditions using a high-speed paper machine, and to provide a method for producing the coated paper. SOLUTION: The method for producing the coated base paper comprises adding to paper stock an amphoteric polyacrylamide having a cationic charge density within the range of 200-1,000 μeq/g, an anionic charge density within the range of 200-1,000 μeq/g, and the ratio of the cationic charge density/anionic charge density within the range of 1.2-5.0 in an amount within the range of 0.05-2.0%, and carrying out papermaking.
