The invention relates to a slip- and leveling agent characterized in that it comprises a copolymer which is obtained by copolymerizing A. at least one unit of a mono- or di perfluoroester of an unsaturated dicarboxylic-acid; B. at least one terminal reactive polysiloxane unit; C. at least one alkyl(meth)acrylate unit or cycloalkyl(meth)acrylate unit and/or (meth)acrylic acid and/or other units originating from vinylic compounds that can form radicals.

Slip- and leveling agent

Polymer of formula (I): In-[(A)-(B)-(A')-(E)]obtained by nitroxyl mediated controlled free radical polymerization whereby an access of acrylate is present, wherein In is the initiator fragment starting the polymerization reaction; A and A&#x2032; are the same or different monomers selected from the group consisting of acrylic acid, methacrylic acid, acrylonitrile, methacrylonitrile, acrylic acid (C-C)alkyl esters, acrylic acid (C-C)hydroxyalkyl esters, methacrylic acid (C-C)alkyl esters, methacrylic acid (C-C)hydroxyalkyl esters, acrylic acid (C-C)alkyl esters or methacrylic acid (C-C)alkyl esters which are substituted by amino, (C-C)alkylamino, (C-C)dialkylamino, &#x2014;SOH, epoxy, fluoro, perfluoro or siloxane groups, styrene, substituted styrene, acrylamide and methacrylamide, N-mono(C-C)alkyl acrylamide, N,N-di(C-C)alkyl acrylamide; provided that the amount of unsubstituted acrylic acid (C-C)alkyl esters or/and methacrylic acid (C-C)alkyl esters is more than 30% by weight based on the weight of the total monomer mixture; and B is at least one multifunctional monomer with two or more ethylenically unsaturated bonds with the proviso than at least one of these ethylenically unsaturated bonds is a high reactive double bond and the other or the others are less reactive double or triple bonds. E is a group bearing at least one stable free nitroxyl radical, which is bound via the oxygen atom to the polymer or copolymer; or a group which results from a substitution or elimination reaction of the attached stable free nitroxyl radical; x and x&#x2032; independently is zero or a number between 5 to 5000; y is a number between 5 to 5000; z is a number 1 or greater than 1 indicating the average number of end groups E attached to the monomer sequence (A)-(B); preferably z is 1; n is a number from 1 to 20, preferably 1.

Polymers obtained via nitroxyl radical polymerization

The invention relates to a dispersing agent comprising: the reaction product of A one or more polyisocyanates having an average functionality of from 2.0 to 5, with B a mixture from B1 monohydroxyl compounds, and B2 monohydroxy-, monocarboxylic acid compounds to form an intermediate, followed by reacting the intermediate with C an unsaturated monohydroxy functional anchoring group.

Polyurethane dispersant

The invention relates to a phosphoric acid ester and salts thereof of the general formula (I), wherein A is a monohydroxyl residue derived from C-C-alkyl-(AO)x-OH or Acyl-(AO)x-OH; or C-C-alkyl-(AO)x-(HA)y-OH or Acyl-(AO)x-(HA)y-OH; or C-C-alkyl-(AO)x-(AA-AO)y-OH or Acyl-(AO)x-(AA-AO)y-OH; or MO-(HA)y-OH or MO-(AA-AO)y-OH; wherein Acyl is an aromatic carboxylic acid residue or a saturated or unsaturated fatty acid residue; AO is a polyC-Calkyleneglycol residue, HA is a hydroxycarboxylic acid or a lactone thereof, AA is a dicarboxylic acid, MO is a monoalcohol, x is 1 to 250, y is 1 to 250, B is a mono-, di-, or tri- or polyhydroxy di-, tri or multi-carboxylic acid residue which is linked via the hydroxy group to the phosphoric acid and via one of the carboxylic acid groups to the monohydroxyl residue [A], the remaining carboxyl acid group(s) is/are free or is/are esterified with a further monohydroxyl residue [A], resulting in branched esters; n is 1-2; m is 1-4. The phosphoric acid esters are used as wetting agent or dispersants.
