Abstract
PURPOSE: To provide a method for producing the objective paper by which the yield of an ultrafine fiber and a filler, and the strength of the paper are improved by using an additive comprising a cationic monomer represented by a specific structural formula, and carrying out the papermaking. CONSTITUTION: The papermaking is carried out by using an additive comprising (A) a cationic monomer of the formula (A is O or NH; n is 2-4; R1 is H or methyl; R2 to R6 are each a lower alkyl; X<-> and Y<-> are each an anion), (B) a cationic or amphoteric polymer having acrylamide and/or methacrylamide as a polymerizing component, and (C) a colloidal silicic acid. Preferably, the component B has 100,000-3,000,000 average molecular weight, and the component C has 1-30 nm average particle diameter.
