Abstract
The present invention provides a laminated body comprising a uniaxially stretched laminate composed of (I) a first thermoplastic resin layer and (II) an adhesion layer which has a lower melting point than said first thermoplastic resin layer (I) and is provided on at least one surface of said thermoplastic resin layer (I), said adhesion layer (II) being composed of a composition containing (A) 100 to 30% by weight of an .alpha.-olefin (co)polymer having a melt flow rate of 0.01 g to 100 g/10 minutes obtained by (co)polymerizing an .alpha.-olefin in the presence of a catalyst which includes at least one compound of a transition metal of Group IV in the Periodic Table containing a ligand having a cyclopentadienyl skeleton, and (B) up to 7% by weight of an olefin-based polymer; in one embodiment, the present invention relates to a nonwoven or woven fabric and a reinforced laminated body, each derived from the laminated body.
