Abstract
A colored, transparent film-forming composition, which is made up of (a) a reaction product of an epoxy group-containing alkoxysilane (a-1) and an amino group-containing alkoxysilane (a-2) having active hydrogen therein, (b) an acid catalyst, (c) an alkali-soluble UV absorber, (d) at least one solvent selected from organic solvents having a boiling point of 100 to 250° C., and (e) a dye and/or a pigment, has a good coating performance and room temperature curing characteristic and can provide a film having good film strength and film removability after use. The coating method of the composition and the removing method of the film obtained from the composition are also described.
