Abstract

Variegated plastic sheet material is moulded (see Group V) from incompletely mixed differently coloured compositions, each of which may comprise a vinyl chloride-vinyl acetate copolymer, stabilizer, plasticizer, filler and appropriate pigment. The following example is given: vinyl chloride-vinyl acetate copolymer 100 pounds, plasticizer (tricresyl phosphate) 80 pounds, stabilizer (white lead) 3 pounds, filler and pigment 417 pounds.
