Abstract

See full text

Provided is a means capable of introducing a sufficient amount of a cationic group onto the surface of silica particles even in a case where a silica raw material having a high silica concentration is used while occurrence of gelation is suppressed at the time of or after addition of a silane coupling agent in production of a cationically modified silica dispersion including modifying raw silica using a silane coupling agent.
