SILICA POWDER, SILICA DISPERSION, PRODUCTION METHOD FOR SILICA DISPERSION, INK-JET RECORDING PAPER, AND METHOD FOR PRODUCING INK-JET RECORDING PAPER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an ink-jet recording paper using a silica powder or silica dispersion, by which occurrence of crack is suppressed and productivity is improved, and also to provide an ink-jet recording paper obtained thereby and a production method for the silica dispersion.

SOLUTION: This silica powder has the isolated silanol group ratio of silica of 1.0 to 4.5, and the silica dispersion is obtained by dispersing the silica powder in an aqueous medium.
