Abstract

The present invention relates to an alkyd resin composition comprising a. 1-60 wt % of an imide compound according to anyone of formulas Ia, Ib, Ic, Id or Ie wherein R1 is H or a C1-C20 optionally substituted hydrocarbon group; R2 and R5 are independently H, or a C1-C20 hydrocarbon group; R3 and R4 are independently H, or a C1-C20 hydrocarbon group; R6 is H or a methyl group; R7 and R8 are independently H, methyl or ethyl; b. 10-40 wt % of an alcohol having a number average hydroxy functionality ≥2.0; c. 30-70 wt % of fatty acids or vegetable oils; d. 0-50 wt % of a mono and/or polyfunctional compound capable of esterification, which compound is different from the compounds used in a, b and c; wherein the wt % is determined relative to the total of weight of compounds a, b, c and d.

First claim

The invention claimed is:

1. An alkyd resin composition comprising
a. 1-60 wt % of an imide compound according to anyone of formulas Ia, Ib, Ic, Id or

wherein R1 is H or a C1-C20 optionally substituted hydrocarbon group;
R2 and R5 are independently H, or a C1-C20 hydrocarbon group;
R3 and R4 are independently H, or a C1-C20 hydrocarbon group;
R6 is H or a methyl group;
R7 and R8 are independently H, methyl or ethyl;
b. 10-40 wt % of an alcohol having a number average hydroxy functionality ≥2.0;
c. 30-70 wt % of fatty acids or vegetable oils;
wherein the wt % is determined relative to the total of weight of compounds a, b, and c.

2. The alkyd resin composition according to claim 1 , wherein R6 is methyl.

3. The alkyd resin composition according to claim 1 , wherein R1 is selected from H, methyl, hydroxymethyl, 1-hydroxyethyl, isopropyl, sec-butyl, 2-methyl-propyl, 2(methylthio)ethyl, benzyl, tolyl and parahydroxytolyl.

4. The alkyd resin composition according to claim 1 , wherein R1 is selected from H and benzyl.

5. The alkyd resin composition according to claim 1 , wherein R2 is H, methyl or ethyl.

6. The alkyd resin composition according to claim 1 , wherein R5 is H, methyl or ethyl.

7. The alkyd resin composition according to claim 1 , wherein R2 and R5 are independently H or methyl.

8. The alkyd resin composition according to claim 1 , wherein R3 is H.

9. The alkyd resin composition according to claim 1 , wherein R4 is H.

10. The alkyd resin composition according to claim 1 , wherein R7 and R8 are both H.

11. An alkyd resin obtained by polycondensation of the alkyd resin composition according to claim 1 .

12. A coating obtained by applying a layer of an alkyd resin according to claim 11 on an object, followed by curing of the layer.

13. An object containing coating layers obtained by the application of an alkyd resin according to claim 11 , followed by curing.

14. An alkyd emulsion comprising an alkyd resin according to claim 11 , wherein the alkyd emulsion is water borne.
