COATING COMPOSITION, COATING, AND OBJECT COATED WITH COATING COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a coating composition including a particle in which a reactive group and a hydrophilic polymer chain are grafted together.SOLUTION: A coating composition includes an inorganic particle in which (a) a compound containing a reactive group and (b) a hydrophilic polymer chain are grafted together. In the coating composition, the inorganic particle contains SiO2, and the reactive group is an acrylate group or a methacrylate group, and the hydrophilic polymer chain contains a monomer unit of ethylene oxide, and further the hydrophilic polymer chain contains the monomer unit of ethylene oxide as many as at least 5 on the average.
