In particular, the range of (a) :( b) = 7: 3 to 8: 2 is desirable. In the acid catalyst used in the present invention, a hydrophilic alkoxysilane compound having a hydroxyl group such as sulfuric acid, nitric acid, phosphoric acid, and para-toluenesulfonic acid is hydrolyzed at room temperature to form a highly reactive silanol, and this silanol is subjected to condensation polymerization. You can use whatever you want to work,
Boron trifluoride can be preferably used.

As the ultraviolet absorber used in the present invention, any of benzophenone type, benzotriazole type, benzoate type, salicylate type, cyanoacrylate type, hindered amine type and the like can be used.
In particular, benzophenone-based and benzotriazole-based are preferred. Specifically, benzophenone-based 2,4-
Dihydroxy benzophenone, 2,2 ', 4,4'-

The ultraviolet absorber used in the present invention is
0.1 to 40 parts by weight based on 100 parts by weight of component (a). Since the colored transparent film forming composition of the present invention does not fade over a long period of time and does not lower the UV cut ratio, it can be used without removing the colored film. In this case, the ultraviolet absorber is used in an amount of 0.1 to less than 5 parts by weight, preferably 0.05 to 0.5 part by weight, per 100 parts by weight of the component (a).
5 parts by weight are preferred. When the film is removed with an alkaline detergent as in the colored transparent film forming composition described in Japanese Patent Application No. 2000-118768, the amount is preferably 5 to 40 parts by weight based on 100 parts by weight of the component (a). In this case, if it is less than 5% by weight, the effect of absorbing ultraviolet light is weak, and the removability of the film is poor. If the alkali-soluble ultraviolet absorber is more than 40% by weight, water resistance and chemical resistance (oil film cleaner and the like) are deteriorated, and blooming occurs. From a practical viewpoint, 15% by weight to 30% by weight is desirable.

If the quencher (quencher) is less than 0.01 part by weight based on 100 parts by weight of the component (a), the coloration of the coating film and the durability of the ultraviolet absorbing effect are not sufficient, and the component (a) 1
If it is more than 5.0 parts by weight with respect to 00 parts by weight, solubility in a solvent is poor, and the effect of the colorant is deteriorated due to its own coloring.

The phenolic antioxidant used in the present invention is used in an amount of 0.01 to 5.0 parts by weight based on 100 parts by weight of the component (a). If the amount of the phenolic antioxidant is less than 0.01 part by weight per 100 parts by weight of the component (a), the persistence of the coloring of the coating film and the durability of the ultraviolet absorbing effect are not sufficient. On the other hand, if it is more than 5.0 parts by weight, the solubility in a solvent becomes poor. The solvent used in the present invention basically has a boiling point of 100 to 250.
