Abstract
A polyorganosiloxane compound is modified such that some silicon-bonded hydroxyl groups are substituted with acid labile groups and/or intermolecular or intramolecular crosslinks form with a crosslinking group having a C—O—C linkage. Cured films of a composition comprising the polyorganosiloxane are useful as interlayer dielectric films on TFT substrates.
