Title: Laminated structure for marking and method of forming a mark

Abstract: A stretchable fabric for marking, having a laminated structure of a first adhesive layer 11 formed of a hot-melt adhesive composed of a thermoplastic polyurethane resin having physical properties including a melting point of 125 to 165.degree. C., a melt viscosity of 8,000 to 15,000 Pas at 150.degree. C., and a 100% modulus of 2 to 8 MPa, an interlayer 20 formed of a thermosetting polyurethane resin which is stretchable and opaque, a second adhesive layer 12 formed of the hot-melt adhesive composed of the thermoplastic polyurethane resin having the above-described physical properties, and a surface layer 30 formed of a thermosetting polyurethane resin which is stretchable and transparent, wherein a mark image has been formed on a front surface of the interlayer 20 or on a back surface of the surface layer 30. This fabric for marking is good in adhesion to an adherend and adhesion durability, can sufficiently stretch while conforming to the stretch of the adherend and can form a mark having excellent resistance to color fading.
