Abstract (en)

[origin: EP0425670A1] A decorative colour-dynamic material comprising a colour-carrying surface (1) has areas of different colours and is covered by a light-transparent protective layer (3). One of the sides of the layer (3) has three-dimensional light-transparent optical elements (4) or alternating transparent and non-transparent areas. The location of the colour-carrying surface areas, which are identical in their colour or optical properties, in relation to the optical elements (4) of the layer (3) is repeated for at least a part of the identical optical elements (4). Different combinations of mutual location of the optical elements and of the colour-carrying surface areas are possible, which increase the colour-dynamic surface effect.
