Abstract

A cationically polymerizable composite coating composition comprising: a) a condensation product of at least one hydrolyzable silane having a fluorine-containing group, b) at least one cationically polymerizable organic resin, and c) a cationic initiator, provides, upon curing, substrates with an alkali-resistant, liquid-repellent coating. The composite coating composition may be used in pattern forming methods.
