Abstract

There is provided a transparent silicone film-forming composition which forms a ultraviolet absorbing and infrared screening film exhibiting film hardness of 6H to 9H or more after curing on a transparent substrate such as glass and plastic. A transparent silicone film-forming composition comprises (a) a reaction product of alkoxysilane (A) having an epoxy group and alkoxylsilane (B) having an amino group with active hydrogen, (b) an acid catalyst, (c) a finely ground ITO cocatalyst and (d) at least one solvent selected from organic solvents. A transparent silicone film-forming composition comprising a reaction product of alkoxysilane (A) having an epoxy group and alkoxylsilane (B) having an amino group with active hydrogen as well as tri- or dialkoxysilane (C) mixed with monoalkoxysilane (D) and / or glycidsilane (E), (b) an acid catalyst, (c) a finely ground ITO cocatalyst and (d) at least one solvent selected from organic solvents.
