Abstract

The present invention relates to a polyester resin obtained by reaction in a process (I) between the following components A to E to obtain a polyester P (the polyester comprising an alkyd resin and/or a saturated polyester resin), where (A) Component A (also referred to herein as the Imide and/or Imide Component) comprises one or more cyclic imides of Formula (1); where R′ represents a divalent optionally substituted saturated C 1-30 organo moiety; and R represents H or a monovalent optionally substituted saturated C 1-30 organo moiety; (A′) Optional Component A′ comprises saturated dicarboxylic acid and/or saturated hydroxyacid and that is not optional in case component A does not comprise a dicarboxylic acid or a hydroxyacid; 1(B) Component B (also referred to herein as the Polyol and/or Polyol Component) comprises at least one saturated polyhydric alcohol; (C) Optional Component C (also referred to herein as the Rosin and/or Rosin Component) comprises naturally occurring rosin, the rosin comprising from 40 to 80 parts per hundred by weight of rosin of an unsaturated mono carboxylic acid comprising at least one C 5-25 cyclohydrocarbo moiety capable of undergoing a Diels Alder or Ene reaction; (D) Optional Component D (also referred to herein as the Fatty Acid and/or Fatty Acid Component) comprises at least one linear C 2-60 hydrocarbo carboxylic acid optionally comprising at least two linoleically unsaturated double bonds; 2(E) Optional Component E (also referred to as the Other Component E) which may comprise at least one monofunctional or polyfunctional monomer other than any of Components A to D.

First claim

The invention claimed is:

1. A polyester resin comprising an alkyd resin and/or a saturated polyester resin, wherein said polyester resin is obtained by reacting the following components A to E in a process (I):
(A) Component A comprises one or more cyclic imides of Formula 1;

wherein R′ represents a divalent optionally substituted saturated aliphatic C1-30 organo moiety; and
R represents H or a monovalent optionally substituted saturated C1-30 organo moiety;

(A′) Component A′ comprises a saturated dicarboxylic acid and/or a saturated hydroxy acid, wherein component A′ is optional only if component A comprises a dicarboxylic acid or a hydroxy acid;
(B) Component B comprises at least one saturated polyhydric alcohol;
(C) Optional Component C comprises naturally occurring rosin, the rosin comprising from 40 to 80 parts per hundred by weight of rosin of an unsaturated mono carboxylic acid comprising at least one C15-25 cyclohydrocarbo moiety capable of undergoing a Diels Alder or Ene reaction;
(D) Optional Component D comprises at least one linear C12-60 hydrocarbo carboxylic acid optionally comprising at least two linoleically unsaturated double bonds;
(E) Optional Component E other than any of Components A to D, wherein Component E is selected from the group consisting of monocarboxylic acids, amines, isocyanates, (poly)ethers, (poly)siloxanes (poly)amides and (poly)acrylates.

2. The polyester resin according to claim 1 , wherein R represents a monovalent optionally substituted saturated C 1-30 organo moiety.

3. The polyester resin according to claim 1 , wherein R represents a monovalent substituted saturated C 1-30 organo moiety.

4. The polyester resin according to claim 1 , wherein R′ represents a divalent substituted aliphatic saturated C 1-30 organo moiety and R represents a monovalent optionally substituted saturated C 1-30 organo moiety.

5. The polyester resin according to claim 1 , wherein R′ represents a divalent aliphatic substituted saturated C 1-30 organo moiety and R represents a monovalent substituted saturated C 1-30 organo moiety.

6. The polyester resin according to claim 1 , wherein R′ represents a divalent substituted aliphatic saturated C 1-20 hydrocarbo, and R represents a substituted saturated C 1-20 hydrocarbo.

7. The polyester resin according to claim 1 , wherein R′ represents an aliphatic saturated C 1-6 hydrocarbylene substituted by one or more imido, carboxy and/or hydroxyl, and R represents a saturated C 1-6 hydrocarbyl substituted by one or more imido, phenyl, carboxy and/or hydroxy.

8. The polyester resin according to claim 1 , wherein the polyester resin is an alkyd resin and wherein Component D is not optional and is present in an amount of at least 20% by weight of the total amount of Components A to E.

9. The polyester resin according to claim 1 , wherein the polyester resin is a saturated polyester resin and wherein the Component C and the Component D are absent.

10. The polyester resin according to claim 1 , wherein the cyclic imides of Formula 1 are represented by one or more citric imide derivatives of Formula 2:

and/or
one more succinimide derivatives of Formula 3:

wherein R in Formulae 2 and/or 3 independently represents H or a monovalent optionally substituted saturated C1-30 organo moiety.

11. The polyester resin according to claim 1 , wherein
the cyclic imides of Formula 1 are represented by one or more citric imide derivatives of Formula 2:

wherein R in Formula 2 independently represents H or a monovalent optionally substituted saturated C1-30 organo moiety.

12. The polyester resin according to claim 1 , wherein the cyclic imides of Formula 1 are selected from the group consisting of:

13. The polyester resin according to claim 1 , wherein the cyclic imides of Formula 1 are selected from the group consisting of:

14. The polyester resin according to claim 1 , wherein the Component A is present in an amount of from 1 to 90% by weight of the total amount of Components A to E and such that the amount of A to E totals 100%.

15. The polyester resin according to claim 1 , wherein the Component B is present in an amount of from 1 to 40% by weight of the total amount of Components A to E and such that the amount of A to E totals 100%.

16. The polyester resin according to claim 1 , wherein at least 20% by weight of the total amount of Components A to E comprise biorenewable material.
