Title:
FILLED PAPER AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/100996
Kind Code:
A1
Abstract:
This invention provides a filled paper containing a coated filler prepared by coating a filler with a composite acrylamide copolymer (composite PAM) comprising (A) an anionic polysaccharide and (B) a cationic and/or amphoteric acrylamide copolymer. The composite PAM is prepared, for example, by mixing the component (A) with 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.
