    Abstract: Novel uses of copolymers for removing and/or reducing the level of deposits in the fuel system and/or injection system of direct injection diesel and/or gasoline engines are provided. What is provided is the use of particular copolymers as fuel additive or lubricant additive; to processes for preparation of such additives, and fuels and lubricants added therewith, such as, more particularly, as a detergent additive; to use of these copolymers for reducing the level of or preventing deposits in the fuel systems and especially the injection systems of direct injection diesel engines, especially in common rail injection systems, for reducing the fuel consumption of direct injection diesel engines, especially of diesel engines with common rail injection systems, and for minimizing power loss in direct injection diesel engines, especially in diesel engines with common rail injection systems; and as an additive for gasoline fuels, especially for operation of DISI engines.

    Abstract: An aqueous paint formulation having an aqueous basecoat and an aqueous dispersion having an at least partially neutralized ethylene copolymer wax, wherein the ethylene copolymer wax contains as comonomers in copolymerized form (A) 12-40 wt % of an ethylenically unsaturated carboxylic acid of formula (I), (B) 60-88 wt % of ethylene, and (C) 0-10 wt % of a further comonomer; or the ethylene copolymer was contains as comonomers in copolymerized form (A′) 5-50 wt % of a comonomer of formula (II), (B′) 50-95 wt % of ethylene, and (C′) 0-20 wt % of a further comonomer; wherein the ethylene copolymer wax comprising the comonomers (A), (B), and optionally (C) has a molecular weight Mw of 10000 to 150000 g/mol, and the ethylene copolymer wax comprising the comonomers (A′), (B′), and optionally (C′) has a molecular weight Mw of 5000 to 40000 g/mol.
