Abstract
Sheets or strips exhibiting a colour-graduation effect, for optical or ornamental use, are made by uniting under heat and pressure two or more lamin of thermoplastic material to form a block and slicing the block in a direction non-parallel to the plane of the lamin , one or more selected lamin being coloured with dyestuff that diffuses or migrates in the plastic mass under the action of heat and the solvents present in the plastic mass. The lamin , which may be of cellulose acetate, nitrocellulose, or vinyl resin, may be assembled to form the block with their planes at an angle to the parallel press surfaces, and the block subsequently sliced parallel to the press surfaces.
