摘要： The present invention provides methods for producing a base paper for coated printing paper and a coated paper by neutral papermaking using a roll and blade gap former type paper machine including a drainage mechanism based on a drainage blade immediately downstream of initial drainage via a forming roll, comprising adding a cationic polyacrylamide-based material having a weight-average molecular weight of 10,000,000 or more determined by intrinsic viscosity measurement as a retention aid to a stock to convert it into paper. According to the present invention, the retention, formation and internal bond strength of the stock can be improved. In the present invention, an anionic microparticle and/or a coagulant can also be used.
