Abstract
A pattern article comprising a copolymer having polymerized units derived from a cleavable crosslinking monomer, to which a pattern is imparted by the release of incipient acid from a thermal acid generator or photoacid generator. The selective release of the acid provides a pattern of high crosslink density and low crosslink density as result of the incipient acid cleaving a portion of the crosslinks.
