OPTICAL RECORDED FILM AND ITS PRODUCTION

摘要

PURPOSE:To produce an optical recorded film having excellent environmental resistance and durability. CONSTITUTION:A film for optical recording is formed from a starting soln. for optical recording contg. a photopolymerizable monomer or oligomer, a photopolymn. initiator, a hydrolyzable and polyconden-sable organometallic compd., a solvent for the organometillic compd., water and a catalyst for accelerating the hydrolysis of the organometallic compd. The formed film is exposed with a pencil of light having intensity distribution and the org. component is removed to produce the objective optical recorded film having apparent density distribution of the resulting metal oxide and/or surface ruggedness.
