  • Patent number: 6132886
    Abstract: Laminates made with an adhesive comprised of a polymerizable composition containing compounds based on N-acylamido-piperazines are provided. Such compounds have the formula: ##STR1## wherein: R.sup.1, R.sup.2, and R.sup.3 are each independently selected from the group consisting of hydrogen and lower alkyl;B is a linking group selected from the group consisting of carbonyl, sulfonyl, amide, and carboxyl;n is one or zero; andR.sup.4 is a radical selected from the group consisting of a higher aliphatic group (i.e. at least four carbon atoms, preferably from about 6 to about 50 carbon atoms), a substituted higher aliphatic group, an alicyclic group, a heterocyclic group, a non-benzenoid aromatic group, and a substituted aromatic group. The adhesive coating is exposed to ultra-violet radiation sufficient to cause the compound to polymerize and thus cure the adhesive.
