Bonded adhesion of wire-shaped individual elements by means of a two-layer acrylate resin-based system

An arrangement of a plurality of wire-shaped individual elements, wherein each individual element has essentially the same dimensional shape, in which arrangement two adjacent individual elements are each connected to one another through a cohesive bond that completely surrounds the plurality of wire-shaped individual elements and is shaped such that a predetermined breakage area is formed for separating the individual elements from one another, wherein the cohesive bond between two adjacent individual elements consists, at least in the region of the predetermined breakage area, of a two-layer system formed from two polymer coatings (A) and (B) of different hardness,

• wherein on the predetermined breakage area the inner coating (A) clusively has contact surfaces with the adjacent individual elements and with the external coating (B) and always represents the softer polymer coating,
• wherein (A) is prepared from
• a) 40 to 90 wt. % of at least one oligomeric linear or branched epoxy-, polyester-, polyether- and/or polyurethane-(meth)acrylate,
• b) 5 to 60 wt. % of at least one monofunctional liquid (meth)acrylate compound or di-, tri-, or poly(meth)acrylate compound,
• c) 0.1 to 20 wt. % of at least one acid group-containing (meth)acrylate compound,
• d) 0.1 to 20 wt. % of photoinitiators,
• e) 0.5 to 20 wt. % of plasticizers that do not represent components a) or b) and are selected from the group consisting of phthalates, glycerine fatty acid esters, and liquid unsaturated low molecular weight compounds,
• and
• wherein (B) is prepared from
• a) 40 to 90 wt. % of at least one oligomeric linear or branched epoxy-, polyester-, polyether- and/or polyurethane-(meth)acrylate,
• b) 5 to 60 wt. % of at least one monofunctional liquid (meth)acrylate compound or di-, tri-, or poly(meth)acrylate compound,
• c) 0.1 to 20 wt. % of photoinitiators,
• d) 0 to 10 wt. % of plasticizers that do not represent components a) or b) and are selected from the group consisting of phthalates, glycerine fatty acid esters, and liquid unsaturated low molecular weight compounds.
