Printed matter is reproduced on the surface of an article made of a homo- or co-polymer of vinyl chloride by transfer from a temporary support member. Preferably, the vinyl chloride is sprayed with a plasticizer, e.g., diiso-octylphthalate, before applying the transfer. The latter may be paper printed with pigments such as carbon based pigments including Carbon Black, a mixture of Benzedene and Chrome Yellows, Phthalocyamine (Blue), a mixture of Carbon Black and Bronze Blue and Calcium Toner (Red). In a preferred embodiment of the invention the printed surface of the support member is contacted with the surface of an article composed of transparent plasticized vinyl polymer and after removing the support member a coating of a pigmented plasticized vinyl polymer is supplied to the printed surface of the transparent article and is then fully gelled e.g. through immersion in a glycerol bath. By selecting the appropriate pigments the background of the design reproduced can be varied over a wide range of colours to produce, for example, abrasion and corrosion resistant labels, particularly ring labels, bearing a title or name. The support member could be contacted with a pigmented plasticized vinyl polymer or copolymer and a transparent coating of plasticized vinyl polymers or copolymers applied thereto, but in that case the design on the support member is in mirror image of that required on the finished product. In the manufacture of a moulded plastic article such as a cloth preprinted transparent thin sections resulting from the application of the method of the present invention may be incorporated in the mould before introducing a curable resinous composition (or plastisol or rigisol in the case of plasticized resin dispersions) so that after curing of the resin (or gellation of plastisol) the transparent sections are bonded to the cured resin (or gelled plastisol). In this way all necessary legends or colours (e.g. lips or eyes on a doll) can be embodied in a shaped article in one operation and, further, be protected from abrasion by a transparent layer.
