Methods for producing coating base papers and coated papers |
| abstract |
A process for producing a coated-paper base and a coated paper in which the coated-paper base is produced by a neutral papermaking method with a gap former papermaking machine of the roll-and-blade former type which has a dehydration mechanism based on a dehydrating blade immediately after initial dehydration with forming rolls. The process includes adding to a stock a cationic polyacrylamide substance having a weight-average molecular weight as measured by the intrinsic-viscosity method of 10,000,000 or higher as a yield improver before the stock is formed. The process can attain improvements in yield based on the stock and in texture and interlaminar strength. Fine anionic particles and/or a coagulant can also be used. |
