- the present invention relates to a method for producing paper. More specifically, a paper manufacturing method characterized by making a pulp slurry containing a neutral sizing agent and, if necessary, a filler, using a specific cationic polymer as a paper quality improver. About.
- the advantages of neutral papermaking or alkaline papermaking are: (1) Less beating energy. (2) There are few problems of equipment corrosion. (3) White water can be closed. (4) The filler (filler) can be freely selected, and inexpensive calcium carbonate can be used. (5) There is little deterioration of paper over time. (6) The printability of paper is good. And so on.
- Paper (1) An expensive neutral sizing agent, such as an alkyl ketene dimer or alkenyl succinic anhydride, is used instead of an inexpensive mouth sizing agent, but the fixation to pulp is poor. (2) Filler is poorly fixed on pulp. (3) The paper strength decreases when the amount of calcium carbonate added is small.

- New paper there are copolymerized polymers whose main component is the quaternary compound of (meta) acrylamide and di-amylamine ⁇ building (meta) acrylamide.
- the effect of increasing the paper strength is insufficient, and the fixing cone of the size agent is favored, so that a good size effect cannot be obtained.
- JP-A-7-12521 ⁇ for the purpose of producing paper ZS having improved dry strength, it is intended to produce gallamine and a beacon which can be co-containing with it.
- a monomer for example, a (meth) acrylamide is combined together, and then a 4 ⁇ polymer obtained by reacting with a .4 agent is used.
- a polymer has been modified to have a high side effect, the size of the size agent has been insufficient and a good size effect has been obtained.
- cation polymers such as knees, and chin, such as knees, etc. Although it is known, none of them can provide a sufficiently satisfactory effect, and as a result, a paper quality improver having an excellent sizing agent and filler effect and an excellent paper strength enhancer effect is obtained. Development is desired.
- the present inventors have used a neutral sizing agent and, if necessary, a filler, and especially because of the excellent yield effect of each additive when producing paper by making paper with neutral or alkaline strength.
- the present invention provides a paper quality improver of the following formula in the presence of a neutral sizing agent and, if necessary, a filler.
- R t represents a hydrogen or methyl group.

- Each component (a) is preferably in the range of 40 to 99 moles, and preferably in the range of 50 to 9 moles. 1 to 60 Mol%, more preferably 3 to 50 mol%, and the component (c) can be used in a range that does not impair the effects of the present invention, but the amount used is also limited by its water solubility and ionization property. .
- nonionic monomers they should be used to the extent that they do not compromise the water solubility of the resulting polymer.
- a cationic monomer it is preferably at most 40 mol%, more preferably at most 30 mol%.
- an anionic monomer it is used in a range smaller than the component (b). ⁇
- the component (a) is less than 40 mol% or the component (b) is less than 1 mol%, it is difficult to sufficiently exert the effects of the present invention. The same applies when the content exceeds 40 mol%.
