<p>A composition finding application for coating substrates comprises (a) a waxy, polymer or copolymer of an alpha-olefin of at least 4 carbon atoms, having a density of from 0.83 to 0.94 and an inherent viscosity of from 0.2 to 0.5, and (b) a mono- or di-carboxylic or -sulphonic acid salt of a metal of Group IA, II or IIIA of the Periodic Table. In examples, the waxy polymers used are polybutene, polypentene, polyhexene and polydecene, and butylene-propylene, propylene-hexene, butene-hexene and octenepropylene copolymers; and the organic acid salts used are Li, Mg and Al hydroxystearates, Na stearate, K myristate, Li hexanoate, Zn ethylhexanoate, Ca decanoate, Na eicosoate, Na sebacate, Mg terephthalate, Li benzilate, Al succinate, K phenylacetate, Li naphthoate, Na palmitate, Mg naphthalate, Zn hydroxynaphthoate, Li adipate, Zn phenolsulphonate, Ca toluenesulphonate, Na benzenesulphonate, Na 3-Me-1 -butanesulphonate, K and Mg di-Me benzene sulphonates, di-Na naphthalene disulphonate, and Li 4-(methylheptadecyl) benzene sulphonate. The compositions have improved tack time and may be used for coating wood, glass, paper, metal foil, fabrics, nuts, bolts, screwdrivers, pliers, ham, bacon and bologna, by the curtain coating or gravure roll techniques.ALSO:A composition finding application for coating substrates comprises (a) a waxy, polymer or copolymer of an alpha-olefin of at least 4 carbon atoms, having a density of from 0.83 to 0.94 and an inherent viscosity of from 0.2 to 0.5, and (b) a mono - or di - carboxylic or - sulphonic acid salt of a metal of Group IA, II or IIIA of the Periodic Table.
