    Abstract: Provided is a coating composition that contains (A) an alkoxysilane containing a compound represented by formula (I) or a hydrolyzate or condensate thereof and (B) a curing catalyst, the coating composition giving a coating having selective ultraviolet radiation transmission optical-characteristics, namely transmitting ultraviolet radiation having wavelengths of 280 nm or more to the greatest extent possible while completely blocking ultraviolet radiation having wavelengths of less than 280 nm, without losing the advantages of a curable coating composition having a siloxane bond.

    (In the formula, the Y moieties may be the same as, or different from, each other, and each denote a group represented by -R 1 -SiR 2 n (OR 3 ) 3-n , R 1 denotes an alkylene group having 1-6 carbon atoms, and R 2 and R 3 may be the same as, or different from, each other, and each denote an alkyl group having 1-5 carbon atoms, n is an integer between 0 and 2.)

    Abstract: To provide an infrared reflective coating composition which is capable of forming an infrared reflective coating film that has both high infrared light reflective properties and high visible light transmittance, while exhibiting high transparency. An infrared reflective coating composition which contains an infrared reflective pigment and a resin component, wherein: the infrared reflective pigment is provided with a layered body wherein dielectric layers and metal thin film layers are alternately laminated, while having one of the dielectric layers positioned as the outermost surface; the dielectric layers are formed from one or more substances selected from the group consisting of titanium dioxide, niobium pentoxide, cerium oxide, tin-doped indium oxide, zinc oxide and tin oxide; the metal thin film layers are formed from a silver compound; the metal thin film layers have film thicknesses of 5-15 nm; if the wavelength λ of incident light in and around the visible region thereof is 250-980 nm and r is the refractive index of the dielectric layers, the thicknesses of the dielectric layers are ((NX)/(4r)) ± 20 nm (wherein N = 1, 2 or 3); and the ratio of the infrared reflective pigment having a particle diameter of 1 µm or less is 10% by volume or less.
