That is, the present invention provides a paper quality improver composition for papermaking; which comprises (A) a compound having lyotropic degree measured by a specific method of not less than 4% and satisfying at least two of (i) standard improved bulky value of not less than 0.02 g/cm3, (ii) standard improved brightness of not less than 0.5 point, and (iii) standard improved opacity of not less than 0.5 point and (B) a water-soluble polymer satisfying an average molecular weight and/or a viscosity thereof of specific value.Type: ApplicationFiled: December 19, 2000Publication date: August 29, 2002Inventors: Yasushi Ikeda, Takaaki Tadokoro, Hiromichi Takahashi
