Abstract
Disclosed are a silica sol composition including silica, an anionic dispersant, a cationic dispersant, an epoxy silane coupling agent, and an organic solvent, and a method for preparing the same. In the silica sol composition, a uniform surface modification of silica particles may be achieved by using an anionic dispersant and a cationic dispersant, and it is possible to effectively enhance the compatibility between a silica filler whose surface is modified with an epoxy group and a resin which is an underfill composition.
