First Claim
Patent Images
1. An alkyd resin, comprising:
- a polyacid component or its acid anhydride;
a first polyol component having at least two hydroxyl groups;
a second polyol component which is a biosourced polyol component having at least one 1,4;
3.6-dianhydrohexitol unit; and
a biosourced oil component or its biosourced corresponding fatty acid;
wherein the alkyd resin comprises less than 10% by mole of aromatic polyacids(s) and cycloalkyl polyacid(s) or acid anhydride(s) of said aromatic polyacid(s) and cycloalkyl polyacids(s), relative to a sum of moles of the polyacid component or its acid anhydride, the first polyol component, the second polyol component, and the biosourced oil component or its biosourced corresponding fatty acid.

Abstract
The object of a present invention is an alkyd resin as well as the method for preparing such a resin, said alkyd resin comprising:
- a preferably biosourced, polyacid component or its preferably biosourced acid anhydride;
- a first polyol component, preferably biosourced, having at least two hydroxyl groups;
- a second biosourced polyol component having at least one 1,4:3,6-dianhydrohexitol unit; and
- a component based on biosourced oil or its corresponding biosourced fatty acid.
