Assignee: KIA CORPORATION
Field: Basic materials chemistry (Chemistry)
Classification: CPC C  B | IPC B  C

Claim 0:
1. A coating composition comprising:
polyurethane; and
amphiphilic silica nanoparticles that are fluorine-amine surface-treated amphiphilic silica particles having (i) a fluorine functional group introduced in a first surface treatment and (ii) an amine functional group introduced in a second surface treatment, with a relatively large amount of fluorine functional group compared to amine functional group;
wherein the fluorine-amine surface-treated amphiphilic silica particles are mixed with polyurethane to form an uneven surface structure through phase separation, and
wherein the coating composition comprises the amphiphilic silica nanoparticles in an amount of 0.3 wt % to 10.7 wt % based on the total weight of the coating composition.
