A method for the preparation of acrylate-modified alkyd resin, comprising the following steps: preparing a reaction mixture with an acid value of greater than 55, preferably greater than 70g KOH/kg, containing a) hydroxyl group-containing alkyd resin with an acid value of less than 15 g KOH/kg and a hydroxyl value of 30 to 200 g KOH/kg, preferably 50 to 160 g KOH/kg, b) acrylate resin with an acid value of 130 to 260, preferably 190 to 220 g KOH/kg, and c) 2 to 15% by weight, preferably 4 to 8% by weight, of a non-aromatic ester with a boiling point of less than 200°C, preferably less than 180°C, at standard pressure as a solvent and entrainer, preferably butyl acetate or butyl propionate, reacting the reaction mixture at a temperature of 170°C to less than 220°C to obtain acrylate-modified alkyd resin with • an acid value that is reduced by at least 5 units, preferably by at least 10 units, in particular at least 20 units, relative to the reaction mixture, and • an absolute acid value of less than 65 g KOH/kg, preferably less than 50 g KOH/kg and in particular preferably greater than 30 to less than 45 g KOH/kg, by means of esterification by azeotropically distilling the ester, wherein the disclosed acid value or respectively hydroxyl value respectively relate to the non-volatile components of the resin or respectively resins. preparing a reaction mixture with an acid value of greater than 55, preferably greater than 70g KOH/kg, containing a) hydroxyl group-containing alkyd resin with an acid value of less than 15 g KOH/kg and a hydroxyl value of 30 to 200 g KOH/kg, preferably 50 to 160 g KOH/kg, b) acrylate resin with an acid value of 130 to 260, preferably 190 to 220 g KOH/kg, and c) 2 to 15% by weight, preferably 4 to 8% by weight, of a non-aromatic ester with a boiling point of less than 200°C, preferably less than 180°C, at standard pressure as a solvent and entrainer, preferably butyl acetate or butyl propionate, a) hydroxyl group-containing alkyd resin with an acid value of less than 15 g KOH/kg and a hydroxyl value of 30 to 200 g KOH/kg, preferably 50 to 160 g KOH/kg, b) acrylate resin with an acid value of 130 to 260, preferably 190 to 220 g KOH/kg, and c) 2 to 15% by weight, preferably 4 to 8% by weight, of a non-aromatic ester with a boiling point of less than 200°C, preferably less than 180°C, at standard pressure as a solvent and entrainer, preferably butyl acetate or butyl propionate, reacting the reaction mixture at a temperature of 170°C to less than 220°C to obtain acrylate-modified alkyd resin with • an acid value that is reduced by at least 5 units, preferably by at least 10 units, in particular at least 20 units, relative to the reaction mixture, and • an absolute acid value of less than 65 g KOH/kg, preferably less than 50 g KOH/kg and in particular preferably greater than 30 to less than 45 g KOH/kg, by means of esterification by azeotropically distilling the ester, • an acid value that is reduced by at least 5 units, preferably by at least 10 units, in particular at least 20 units, relative to the reaction mixture, and • an absolute acid value of less than 65 g KOH/kg, preferably less than 50 g KOH/kg and in particular preferably greater than 30 to less than 45 g KOH/kg, by means of esterification by azeotropically distilling the ester, wherein the disclosed acid value or respectively hydroxyl value respectively relate to the non-volatile components of the resin or respectively resins.
