(57) [Summary] [Problem] When powder is dispersed in water at a high concentration, the viscosity is low, good fluidity is maintained, and in a low concentration system, there is little powder sedimentation and good dispersion stability. An aqueous dispersion composition for paper is provided. The dispersant has a molecular weight of 1,0 to 100 parts by weight of a powder insoluble in water and having a particle size of 50 microns or less. 0.05 to 30.0 parts by weight of a polyacid amino acid and / or a salt thereof having a molecular weight of 100 to 50,000 and water having a molecular weight of 10 to 10,000. An aqueous dispersion composition for paper, comprising parts by weight. |
