Functional urethane resin film and laminated film comprising the film

A laminated film comprising a multi-layer functional film torred by successively laminating an optionally provided release layer (I), a cementing material layer (II) formed from a pressure-sensitive adhesive or a bonding adhesive and an urethane resin layer (III) formed from a water based urethane resin dispersion (A), showing practically no stickiness per se, and having a tensile elongation at breakage in the range of 50 to 1000% as a value measured by the use of a sample of 30 mm in length, 10 mm in width and 0.05 mm in thickness under the conditions of a temperature of −10° C. and a stress rate of 200 mm/min.

A laminated film comprising a multi-layer application film formed by laminating at least three resin films and essentially containing a top layer film (IV) formed from a crosslinkable resin coating composition (B), a cementing material layer (VI) formed from a pressure-sensitive adhesive or a bonding adhesive as an under layer, and a film (V) formed from a thermoplastic resin (C) comprising a water based urethane resin dispersion (A) between the layer (IV) and the layer (VI), showing practically no stickiness per se, and having a tensile elongation at breakage in the range of 50 to 1000% as a value measured by the use of a sample of 30 mm in length, 10 mm in width and 0.05 mm in thickness under the conditions of a temperature of −10° C. and a stress rate of 200 mm/min.

A laminated film comprising a multi-layer colored film formed by successively laminating an optionally provided release layer, a bonding material layer (VII) formed from a pressure-sensitive adhesive or a bonding adhesive, a clear layer (VIII) formed from a water based urethane resin dispersion (A), showing practically no stickiness per se, and having a-tensile elongation at breakage in the range of 50 to 1000% as a value measured by the use of a sample of 30 mm in length, 10 mm in width and 0.05 mm in thickness under the conditions of a temperature of −10° C. and a stress rate of 200 mm/min., a colored layer (TX) formed from the water based urethane resin dispersion (A) and a colorant (D), showing practically no stickiness per se, and having a tensile elongation at breakage in the range of 50 to 1000% as a value measured by the use of a sample of 30 mm in length, 10 mm in width and 0.05 mm in thickness under the conditions of a temperature of −10° C. and a stress rate of 200 mm/min., and a clear layer formed from a crosslinkable resin coating composition (B).
