Photoinduced acid catalyzed depolymerization of degradable polymers

摘要

An imaging process based upon the ultraviolet light induced acid catalyzed degradation of a composition containing at least one acid degradable polymer of the formula: H ¦ ---C-O--- ¦ Rn WHEREIN R is an aliphatic hydrocarbon radical of 1 to 6 carbon atoms, a chlorinated aliphatic hydrocarbon radical of 1 to 6 carbon atoms or a nitrile substituted aliphatic hydrocarbon radical of 1 to 5 carbon atoms; and N IS AT LEAST 50.
