に望ましい。The average particle size of the inorganic oxide colloidal particles is 100 when blended in the coating composition.
It is preferably 0 nm or less, and particularly preferably in the range of 7 to 800 nm. Inorganic oxide colloidal particles having transparency, such as SiO 2 and SiO 2 —Al 2 O 3 are particularly desirable.

容易に脱水縮合反応を起こして結合する。[Chemical 3] The chain portion represented by has water repellency, while R 1 and R 2 at the ends show hydrophilicity. Therefore, the polysiloxane compound easily causes a dehydration-condensation reaction with the -OH group on the surface of the inorganic oxide colloidal particles to bond.

くない。好ましいｎの値は、５〜７０の範囲である。In the general formula of the polysiloxane compound, when the value of n is less than 3, the water repellency becomes small,
When the inorganic oxide colloidal particles are blended in the coating composition, it becomes difficult to exert a desired antifogging effect. On the other hand, when the value of n is more than 100, the dispersibility in an organic solvent, a resin composition, etc. becomes poor, which is not preferable. The preferred value of n is in the range of 5-70.

A propyl group, a butyl group, etc. are shown. Also, R 1 and R
2 is a hydrophilic group, and the subscripts X, Y, or Z of these groups
The larger the molecular weight depending on, the better the wettability of the coating film. However, if the molecular weight exceeds the above range and the molecular weight is too large, the dispersibility of the colloidal particles in the nonpolar resin becomes poor. Furthermore, the obtained coating composition tends to be inferior in adhesiveness to a substrate, water resistance and the like, which is not preferable. On the other hand, when the molecular weight is smaller than the above range, the desired antifogging effect cannot be obtained in the coating composition.
