In a reinforcing tape for a slide fastener, which comprises a transparent elastomer film and an adhesive layer superposed on the reverse side thereof, an intermediate layer (an anchor coat layer) having a thickness thinner than the thickness of the elastomer film and that of the adhesive layer is interposed between the elastomer film and the adhesive layer. In a preferred embodiment, a polyamide elastomer film or polyester elastomer film is the elastomer film, a polyester anchor coat agent is the intermediate layer, and a polyester hot-melt adhesive is the adhesive layer. The thickness of the intermediate layer is 0.5 to 10 &mgr;m, preferably 2 to 3 &mgr;m.

Reinforcing tape for slide fastener

A slide fastener comprises a pair of dyed fastener tapes each having a row of coupling elements attached to the fastener tape along a longitudinal edge thereof and at least a pair of reinforcing tapes attached to a terminal part of each of the fastener tapes. The reinforcing tape comprising a transparent elastomer film and an adhesive layer superposed on the reverse side of the elastomer film is attached by welding or fusion bonding to the terminal part of the dyed fastener tape through the medium of the adhesive layer and has a knurled surface at the welded part.

Reinforcing tapes for slide fastener

A slide fastener of synthetic resin which has regularly spaced elements formed and fixed to the edge of fastener tape by the injection molding of the molten mass of the synthetic resin is disclosed. The fastener tape is formed of polyethylene terephthalate and the elements of slide fastener are made of a polymer alloy of polybutylene terephthalate with polypropylene or polyethylene terephthalate.

Slide fastener made of synthetic resin

The present invention provides fastener elements for use in a slide fastener in which, regardless of the quality of material, a metallic coating layer having an excellent adhesiveness and 0.001 to 1.0 .mu.m in thickness is simply and easily formed on the surface of a fastener element member so that the surface thereof gives out the luster of metal. The surface of the metallic coating layer may further be formed at least thereon with a finishing coat layer. In the present invention, there is further provided a slide fastener having a light weight and flexibility in which such a fastener element member as being made synthetic resin having the luster of metal on the surface thereof.

Slide fastener and fastener elements therefor

A slide fastener comprising a pair of stringer tapes which are separable into identical halves by means of a pin-and-box separator, a reinforcing strip attached to an end of each of the stringer tapes and an adhesive film fusible to bond the strip to the tape. Both of the stringer tape and the reinforcing strip are made of the same type of fibrous materials, while the adhesive film is a modified polyester or a copolymeric polyamide depending upon the type of materials chosen for the stringer tape and the strip.
