Preferably, the amphoteric copolymer is obtained by polymerizing monomer ingredients that it essentially contain a hydrophobic monomer (A), a cationic monomer (B), and an anionic monomer (C) and that an anion equivalent of the monomer (C) is 0.1 to 90% of a cation equivalent of the monomer (B), in which a rate of quaternizing of the cationic groups is not less than 40% by mole. The paper or the paperboard contains the above papermaking internal sizing agent.Type: GrantFiled: March 6, 2008Date of Patent: August 14, 2012Assignees: Harima Chemicals, Inc., Nippon Paper Industries Co., Ltd.Inventors: Kazunari Sakai, Takahiro Fujiwara, Kazushige Inaoka, Takashi Yamaguchi, Masaki Ito, Yasunobu Ooka
