Abstract
A reclosable mechanical fastener comprising a fastening component having a surface structure by which two such fastening components can become releasably attached. The novel fastening component is a composite of a tough substrate and a fastening layer that forms said surface structure, which fastening layer is formed from a cured oligomeric resin composition having one or more like or different hard segments, one or more like or different soft segments, and one or more like or different monovalent moieties containing a radiation-sensitive, addition-polymerizable, function group. The novel fastener forms stronger linkages than were possible with similar fasteners of the prior art.
