In a heat-shielding film formed of addition-curing silicone resin containing organopolysiloxane, organopolysiloxane includes the combination of a plurality of units including at least a RSiOunit (a T unit), a RRSiOunit (a D unit), and a RRRSiOunit (a M unit) (in each unit, Rto Ris aliphatic hydrocarbon or hydrogen), and the molar ratio of the T unit, the D unit, and the M unit among all structural units is T:33.3 mol % to 71.4 mol %, D:11.1 mol % to 42.9 mol %, and M:7.0 mol % to 42.9 mol %.

Addition-curing silicone resin for producing heat-shielding film, method for forming heat-shielding film on inner surface of combustion chamber of engine by means of addition-curing silicone resin, heat-shielding film, and heat shielding method for reducing or preventing heat dissipation from combustion chamber of engine to outside by means of heat-shielding film

A coating composition for forming a coating film including particles and a resin binder is so configured that a content of the particles in the coating film is more than 30 vol%, the coating composition includes the particles, a raw resin of the resin binder, and a solvent, and a ratio V/D is 2.5 or less, where V is a volatilization rate (g/m&#xb7;s) of the solvent, and D is a diffusion coefficient (10m/s) of the solvent in the coating composition.
