<p><P>PROBLEM TO BE SOLVED: To provide a long sheet-like material that has a smooth and continuous design in a length direction. <P>SOLUTION: There is provided a long sheet-like material which has a surface layer having a continuous design in a length direction. The design is formed by orientation differences of non-spherical magnetic pigment in the surface layer. It is preferable that the layer containing the non-spherical magnetic pigment is smooth, that the non-spherical magnetic pigment is thin plate like, and that the non-spherical magnetic pigment is plate-like mica onto which a ferromagnetic body is coated. Also, it is preferable that the surface layer includes a surface skin layer that contains non-spherical magnetic pigment and an adhesive layer that does not contain non-spherical magnetic pigment, and that the surface layer contains non-spherical magnetic pigment in an amount of 1-30 wt.% or that the surface skin layer contains non-spherical magnetic pigment in an amount of 5-50 wt.%. The method for producing a long sheet-like material is a laminate method in which a polymer elastic body solution containing non-spherical magnetic pigment is coated on a release paper and an object having magnetic force is applied from a back side direction to form a design. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
