The present invention is a siloxane-based resin composition including a siloxane-based resin and an imidosilane compound having a specific structure. Moreover, the present invention is a siloxane-based resin composition including a siloxane-based resin which is a reactive product to be obtained by hydrolyzing an alkoxysilane compound and an imidosilane compound having a specific structure and then making the resulting hydrolysate undergo a condensation reaction. According to the present invention, it is possible to form a cured film excellent in adhesion.

Siloxane-based resin composition

A positive photosensitive siloxane composition having high photosensitivity and having such properties as high heat resistance, high transparency and low dielectric constant may be used to form a planarization film for a TFT substrate, an interlayer dielectrics or a core or cladding of an optical waveguide. The positive photosensitive siloxane composition includes a siloxane polymer, quinonediazide compound and solvent, and a cured film formed of the composition has a light transmittance per 3 &#x3bc;m of film thickness at a wavelength of 400 nm of 95% or more.
