PROBLEM TO BE SOLVED : To provide a silicone-based coating material from which a heat-shielding coating film excellent in surface uniformity and adhesion and having high hardness and properties capable of sufficiently shielding near infrared rays can be obtained when the silicone coating material is applied on a transparent base material such as glass.SOLUTION : The silicone-based coating material is used in such a manner that a silane solution composed of an alkoxysilane hydrolysate and a dispersion of ITO particles are mixed. The silane solution uses, as a base, a hydrolysis mixture of a tetraalkoxysilane (A component) that is a main component and represented by general formula (I) : Si(OR)(where, Ris a 1-4C alkyl group) and a trialkoxysilane (B component) represented by general formula (II) : RSi(OR)(where, Rand Rare each a 1-4C alkyl group). To the hydrolysis mixture, a hydrolysate of an ω-glycidoxyalkyl trialkoxysilane (C component) represented by general formula (III) (where, Ris H or CH, Ris a 1-4C alkylene group, and Ris a 1-4C alkyl group) is added. |
