Abstract

The present invention relates to a radiation curable composition comprising at least one (meth)acrylated compound compound (A); and at least one inert polyester (B) that is prepared from a (i) polyol component comprising at least one cyclic ether polyol and (ii) from a polyacid component. The present invention further relates to their preparation and uses.

First claim

The invention claimed is:

1. A radiation curable composition comprising at least one (meth)acrylated compound (A); and at least one inert OH-terminated polyester (B) that is prepared from a polyol component comprising at least one cyclic ether polyol and from a polyacid component, wherein said inert OH-terminated polyester (B) has a hydroxyl value of between 30 and 150 mg KOH/g.

2. The composition of claim 1 , wherein said polyol component comprises from 5 to 100 wt % of cyclic ether polyols.

3. The composition of claim 1 , wherein said polyol component comprises isosorbide as well as one or more of: as ethylene glycol, diethylene glycol and/or hydrogenated bisphenol A, and optionally neopentylgycol; and wherein the polyacid component comprises phthalic acid and/or phthalic anhydride.

4. The composition of claim 1 , wherein the inert OH-terminated polyester (B) is further prepared from one or more mono-carboxylic compounds.

5. The composition of claim 4 , wherein said mono-carboxylic compounds are selected from one or more of 2-(4-chlorobenzoyl) benzoic acid, o-benzoylbenzoic acid, 2-(4-phenylbenzoyl)benzoic acid, benzoic acid and substituted benzoic acid.

6. The composition of claim 4 , wherein the hydroxyl value of the inert OH-terminated polyester (B) is between 30 and 120 mg KOH/g.

7. The composition of claim 1 , comprising
at least one inert OH-terminated polyester (B) that is prepared from a polyol component comprising at least one cyclic ether polyol and from a polyacid component, and
at least one inert OH-terminated polyester (B) that is prepared from one or more mono-carboxylic compounds.

8. The composition of claim 1 , wherein the inert OH-terminated polyester (B) has a number average molecular weight of between 500 and 5000 Daltons.

9. The composition of claim 1 , wherein the (meth)acrylated compound (A) is a reactive diluent selected from di(meth)acrylates and/or tri(meth)acrylates.

10. The composition of claim 1 comprising at least 15% by weight of inert resins based upon the total weight of the composition, wherein the inert resins comprise the at least one inert OH-terminated polyester (B) and, optionally, other inert resins (C) that are different from the at least one inert OH-terminated polyester (B).

11. A coating composition, ink or varnish prepared from a composition according to claim 1 .

12. An article coated, partially or entirely, with a composition according to claim 11 .

13. A method comprising applying the composition according to claim 1 as a primer on metal or plastic and/or as an adhesion promoter for inks on a plastic.

14. A method comprising applying the inert OH-terminated polyester (B) of claim 1 as a primer on metal or plastic and/or as an adhesion promoter for inks on a plastic.
