Laminates made with an adhesive comprised of a polymerizable composition containing compounds based on N-acylamido-piperazines are provided. Such compounds have the formula: wherein: R1, R2, and R3 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; and R4 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.
