Abstract

A heat shielding material is provided. The heat shielding material includes a sheet material and a pigment layer covering the sheet material. The pigment layer includes a crosslinking structure formed of siloxane functional groups and pigments dispersed in the crosslinking structure. A heat shielding composition and a heat shielding structure employing the same are also provided.

Claims
