Abstract
Disclosed is a patterned film forming laminated sheet comprising a multi-layer construction prepared by successively laminating a release sheet layer (1), a pressure-sensitive adhesive layer (2), a base sheet layer (3), and a patterned film layer (4) or further laminating a pigmented print layer (5), said patterned film layer (4) being prepared by a process which comprises coating a fluid coating composition containing a powdery magnetic material on one side of the base sheet layer (3) to form a fluid film, and acting a magnetic force on the powdery magnetic material contained in the fluid film in a fluid state to form a pattern.
