The present invention pertains to a method for extrusion coating of a polymeric material, especially a thermoplastic polymeric material, on steel, tin plated steel or zinc coated steel sheets, and to steel, tin plated steel or zinc coated steel sheets having a polymeric material coated thereon obtainable in such a method, as well as to the use of such steel, tin plated steel or zinc coated steel sheets having a polymeric material coated on at least one surface of the sheet to produce coils or formed parts made from such coils.

Disclosed is an aqueous coating agent comprising: (A) a copolymer of ethylene with a carboxylic acid derivative having an ethylenic double bond; (B) a basic material; and (C) particles having melting point of 100 C. or more, and is further a paper substrate coated with the aqueous coating agent.

A fiber preparation treated with an aqueous polyolefin dispersion having a pH value from 7.5-9.4 containing from 50 to 100 wt. % of an aqueous dispersion A and from 0 to 50 wt. % of a compound B. Dispersion A comprises from 41 to 98 wt. % of A1, one or more copolymers of ethylene and (meth)acrylic acid having a content of (meth)acrylic based groups of at least 14 wt. % based on the total weight of the copolymer, from 1 to 59 wt. % of A2, one or more olefinic structure units containing hydrocarbon polymer, and from 0-35 wt. % of additive different from A1 and A2, based on the solid content of dispersion A. Compound B is a material dispersible or soluble in water and different from the ingredients of dispersion A. The wt. % of A and B is based on the solid content of the aqueous polyolefin dispersion.
