Title:
SIZING AGENT COMPOSITION FOR PAPERMAKING AND PRODUCTION OF PAPER USING THE SAME
Document Type and Number:
Japanese Patent JP3240735
Kind Code:
B2
Abstract:
PURPOSE: To produce paper using a ketene dimer-based sizing agent composition capable of developing sufficient sizing effect in a short time in papermaking, i.e., excellent in rising property of sizing effect.
CONSTITUTION: This sizing agent composition is obtained by dispersing a ketene dimer-based compound (A) which is substituted with aliphatic hydrocarbon groups or aromatic hydrocarbon groups into water using a copolymer (B) consisting essentially of a salt of di(meth)allylamine and a polymerizable nonionic compound such as (meth)acrylamide as a dispersing agent. The sizing agent is applied in either one step in papermaking steps, e.g. the step of pulp slurry to produce the objective paper. Thereby, rising property of sizing effect is improved.
