▎ 摘　　要

NOVELTY - Complex functional pigments has a Brunauer, Emmett and Teller (BET) specific surface area of 50-2000 m2/g and absorptivity in the visible region, includes a titanium oxide airgel doped with noble metals and/or transition metals. USE - The complex functional pigments is useful in coating composition (claimed). ADVANTAGE - The composite functional pigment is possible to effectively functionalize the paint while minimizing the solid content of the paint composition and has heat insulation, sound insulation, beautification, weather resistance, durability, chemical resistance, anti-bio-resistance, excellent dispersibility when added in a high content in the paint composition and wide color realization area of the coating film. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: coating composition, comprising complex functional pigments; and producing complex functional pigments, comprising (a) preparing a first solution containing a titanium precursor, (b) mixing an acid with the first solution and hydrolyzing to prepare a first sol, (c) preparing a second solution containing a metal precursor, and (d) preparing a reaction solution by mixing a second solution with the first sol and performing a condensation reaction to prepare a gel.
