    Abstract: The invention relates to a moulded article exhibiting an optical effect and consisting essentially of cladded core particles whose coat forms a matrix and whose core is essentially solid and is provided with essentially monodisperse size distribution. Said invention is characterised in that the inventive mould article is produced by a method consisting of a) heating a cladded core article to a temperature of a fluid state of the coat thereof, b) extruding the liquid claded core particles from a) by means of an extruder provided with a sheet die and c) transferring extruded material from b) by means of a rolling mill. A method for producing said moulded articles and for the use thereof is also disclosed. The materials produced according to said invention exhibit a uniform colour effect dependent on a viewing angle.
