STARCH-BASED LIQUID COMPOSITION FOR PRETREATING FILLER, FILLER PRETREATED WITH THE COMPOSITION FOR MAKING PAPER, AND PAPER COMPRISING THE FILLER

摘要

PURPOSE: Paper with filler for a paper pretreated with filler. Is provided to reduce usage of pulp resource which is expensive as ash content in the paper is able to be increased by more than 3 % based on a general wood-free paper without reduction in a paper property. CONSTITUTION: A liquid component for pretreatment of filler contains a starchy in which a positive ion monomer is graft polymerized. An amount of the starch is 50-90 weight% and an amount of the positive ion monomer is 10-50 weight% per a 100 weight% of total composed of the starchy and the positive ion monomer. Filler for pretreated paper is a liquid component and is obtained by treating raw material filler in advance. The paper includes the filler for pretreated paper.
