摘要: A method of producing pigmented extrudates or mouldings from an unpigmented thermosetting moulding material, which comprises roughly blending a pigment component with an aminoplast moulding material substantially free from pigment and having an average particle size not greater than 150 microns, and completely dispersing the pigment compound through the aminoplast moulding material by progressing the rough blend through an extruder or injection moulding machine having a barrel grooved in accordance with German Offenlegungschrift No. 2514307, and extruding or injection moulding the resulting pigmented material.
