Claim 0:
1. A method of producing a substrate having a decorated surface, the method comprising:
providing one or more pluralities of coloured particles having an initial colour and an exposed surface comprising one or more polymers, wherein the coloured particles of the one or more pluralities of coloured particles have a melt flow index (MFI) of up to about 50;
providing a substrate having an exposed surface to be decorated comprising one or more polymers, wherein the substrate is a precursor of a module to be molded;
molding the precursor between a first forming surface and a second forming surface to form the module;
wherein the first forming surface comprises at least one die face configured to mold three dimensional surface features onto at least a portion of a top surface of the module;
wherein the one or more pluralities of coloured particles are applied to at least a portion of the at least one die face prior to the molding step; bringing into contact the one or more pluralities of coloured particles and the exposed surface to be decorated during the molding step; and
exposing the coloured particles and/or the exposed surface to be decorated to a temperature and a pressure sufficient to cause the coloured particles to fuse into or fuse to or coalesce with the exposed surface to be decorated, the temperature and the pressure being controlled over a period of time to thereby produce a molded module having a decorated surface.
