Abstract:
A radiation-curable pressure-sensitive adhesive composition, comprising:(a) a pressure-sensitive adhesive component comprising at least one poly(1-alkene);(b) about 2 to about 100 parts by weight, per 100 parts of said pressure-sensitive adhesive component, of a polymer component comprising at least one non-pressure-sensitive adhesive polymer having reactive sites for crosslinking; and(c) a sufficient amount of at least one crosslinking agent to crosslink (a) and (b) to provide on curing a crosslinked pressure-sensitive adhesive composition with (i) shear strength at least 300% greater than, and peel adhesion not less than 80% of, that of a crosslinked composition consisting essentially of the reaction product of components (a) and (c), or with (ii) shear strength and peel adhesion each not less than 80% of those of a crosslinked composition consisting essentially of the reaction products of components (a) and (c) produced under (1) the same cure conditions including the same curing energy dosage, except at a process speed that is at least 100% faster than the process speed for producing the crosslinked reaction product consisting essentially of components (a) and (c), or (2) the same process speed, but with cure conditions comprising a curing energy dosage that is at least 50% less than the curing energy dosage for producing the crosslinked reaction product consisting essentially of components (a) and (c).
