The invention relates to mixtures of at least one acrylic resin dispersion A and a second dispersion B which is at least one of a polyurethane dispersion B1 which comprises, in its polymer, moieties derived from grafted fatty acids, and a mixture B2 of a polyurethane dispersion B21 and an aqueously dispersed alkyd resin B22, and to a method of use thereof for coating of porous substrates.

Aqueous binder compositions

The invention relates to a polyurethane P comprising a moiety derived from a polyfunctional isocyanate F, and a hydroxyfunctional compound ABCE made from a grafted fatty acid AB which in turn is made from a fatty acid A having at least one olefinic unsaturation, and grafted with a mixture B of olefinically unsaturated monomers which mixture comprises at least one acid-functional olefinically unsaturated monomer B1, wherein the grafted fatty acid AB has on average at least 1.1 acid groups per molecule, at least one polyhydric alcohol C having at least two hydroxyl groups, and at least one fatty acid E, to a process of making this polyurethane, and to a method of use thereof in the form of an aqueous dispersion to formulate coating compositions.

Polyurethane dispersions, a process of making, and a method of use thereof

The invention relates to a graft copolymer latex comprising the which comprises a graft copolymer ABC of at least one olefinically unsaturated monomer C and at least one modified alkyd resin A2B or modified oil A1B which modified alkyd resin A2B or modified oil A1B have chain-pendant olefinically unsaturated groups, to a process for its preparation, and the use thereof a binder in coating compositions.

Graft copolymer latices

The invention is directed to an aqueous coating composition comprising a combination of a high molar mass urethane-modified alkyd resin A and a reactive diluent D, characterized in that the alkyd resin A has moieties derived from grafted fatty acids A1 which are graft products of fatty acids A11 having at least one olefinic unsaturation, on average, per molecule, and olefinically unsaturated linear or branched aliphatic acids A12 preferably having from three to ten carbon atoms, polyhydric aliphatic alcohols A2, fatty acids A3, polyfunctional isocyanates A4, and the reactive diluent D has a hydroxyl number of at most 5 mg/g, and comprises moieties derived from olefinically unsaturated fatty acids D1, and polyoxyalkylene glycols D2 or their monoethers, to a process of preparation thereof, and a method of use thereof for coating of wood, fiberboard, textiles, paper, cardboard, leather, and thermoplastic materials.

Urethane modified water-reducible alkyd resin compositions

Urethane modified water-reducible alkyd resins ABCD, comprising moieties derived from polyhydric alcohols A, modified fatty acids B made h&#x3b3; grafting olefinically unsaturated carboxylic acids B2 onto fatty acids B1, ungrafted fatty acids C and polyfunctional isocyanates D, a process for their production, and a method of use thereof in coating binders

Urethane modified water-reducible alkyd resins

Urethane and siloxane modified water-reducible alkyd resins ABCDE, comprising moieties derived from polyhydric alcohols A, modified fatty acids B made by grafting olefinically unsaturated carboxylic acids B2 onto fatty acids B1, ungrafted fatty acids C, silanol or alkoxysilyl functional siloxane oligomers or polymers D, and polyfunctional isocyanates E, a process for their production, and a method of use thereof in coating binders.

Polysiloxane and urethane modified water-reducible alkyd resins

The invention relates to hydroxyl-functional binder components ABC containing a linear or branched main chain having a polymethylene structure &#x2014;(CH)&#x2014; or a polyester structure or a structure derived from the fatty acid esters of glycerin or other polyvalent alcohols. The invention is characterized in that said components have grafted cyclic imide structures on the main chain, wherein the imide-nitrogen atom is substituted by a hydroxyalkyl group or a hydroxyalkyl-aryl group. The invention also relates to method for the production of said components by reacting oleofinically unsaturated acid anhydrides B and hydroxyamines C and to the utilization of the inventive components for the formulation of binders.
