A moulding composition comprises a mouldable organic synthetic plastics, 0.01-5% by wt. of an inorganic acicular or lamelliform pigment having a smooth surface and 5-60% of fibres of length 2-2000 m which are not soluble in the plastics and do not melt under the conditions met in the production of an article which may be produced from this composition. The plastics may be polystyrene, an unsaturated polyester/styrene resin, or polycaprolactam. The pigment may be aluminium or a copper/zinc alloy. The fibres may be of glass which may be fed as a bundle into a melt of the plastics and then comminuted to the given length. The polycaprolactam based composition may contain calcium stearate as lubricant.
