Abstract

The invention provides a composite composition comprising a cationically polymerizable organic resin, a cationic photoinitiator, a hydrolysate and/or condensate of at least one hydrolysable silane compound and inorganic nanoparticles. The composite composition is suitable for the preparation of patterned moulded articles or substrates having a patterned coating, in particular by photolithography. Micropatterns obtained show improved properties, such as a high shape stability and an excellent elastic modulus.
