Abstract
A core-sheath filament including a crosslinkable adhesive core that can be cured using ultraviolet or visible light radiation. These crosslinkable adhesive core compositions can provide very high bond strength and are capable of replacing traditional mechanical fasteners in many industrial applications. Core-sheath filaments including such crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions contain pendant aromatic ketone groups or pendant (meth)acryloyl groups that, upon exposure to ultraviolet radiation, result in the formation of crosslinks within the polymeric material. The crosslinked compositions can function as pressure-sensitive adhesives.
