FILLED PAPER AND METHOD OF MANUFACTURING THE SAME |
摘要 |
There is provided a filled paper containing a coated filler obtained by coating a filler with a acrylamide copolymer (composite PAM) comprising (A) an anionic polysaccharide and (B) a cationic and/or an amphoteric acrylamide copolymer. The composite PAM is obtained, for example, by mixing the component (A) and the component (B). Since the filler is treated with a combination of the components (A) and (B) different from each other in charge properties and structure, suitable coagulation effect can be attained and the coated filler has excellent affinity for pulp slurry. Therefore, even in the case of a highly filled paper, a large paper strengthening effect can be attained by using a small amount of the chemical agent. |
