Radiation sensitive composition, microlens, process for forming microlens and use of the microlens

摘要

A radiation sensitive composition containing inorganic oxide particles; a copolymer of at least one unsaturated compound selected from the group consisting of an unsaturated carboxylic acid and an unsaturated carboxylic anhydride and other unsaturated compound different from the unsaturated compound; a polyfunctional unsaturated compound having at least two ethylenically unsaturated groups in the molecule; and a radiation sensitive polymerization initiator. The composition is useful for making a microlens.
