Abstract
This invention relates to a composite construction for use as a label or a tape to be adhered to a second substrate comprising a rubber-based material (e.g., vehicular tire), said composite construction comprising: a first substrate (e.g., paper, polymer film or combination thereof), said first substrate having a face side and an underside opposite said face side; an adhesive layer; and a barrier layer adhered to the underside of said first substrate and positioned between said first substrate and said adhesive layer, said barrier layer comprising a radiation cured cross linked cycloaliphatic epoxide derived from at least one cycloaliphatic epoxy compound, at least one polyol and at least one photoinitiator, said barrier layer being substantially impervious to migratory components in said adhesive layer and said second substrate. In one embodiment, a release liner is adhered to the adhesive layer. In one embodiment, the composite construction is adhered to the second substrate.
