Abstract
The present invention relates to amine synergists comprising the structure element of a substituted 1,3-propanedione and their use in radiation or energy curing by actinic light. The amine synergists of the present invention are particularly useful for printing and coating materials wherein low migration and/or low odor is required, such as food packaging and other sensitive packaging applications.
Claims21
An aminoketone compound comprising the structure of a 1,3-propane-dione, of general Formula I:
- wherein the —NR1R2 substituent can be in any one of the ortho, meta or para positions relative to the C═O-substituent on the phenyl ring;
- R1 and R2 are each independently selected from the group consisting of H, a branched or unbranched C1 to C12 alkyl, a branched or unbranched C1 to C12 cycloalkyl, a branched or unbranched C2 to C12 heteroalkyl, a branched or unbranched C2 to C12 heterocycloalkyl, a C3 to C12 aryl, a C3 to C12 heteroaryl, or wherein R1 and R2 together form a heterocycle;
- wherein Q is either:
- i) methyl or a straight or branched alkyl group and wherein m=1;
- or
- ii) the remaining part of a mono-, di- or multifunctional acrylate monomer, oligomer or polymer wherein the functionality of the acrylate of which Q is derived is at least m, but can be higher which results in remaining acrylate functionality on Q, and wherein m is an integer≥1;
- and
- Z is selected from the group consisting of a C3 to C18 aryl or an optionally substituted C3 to C12 heteroaryl;
- wherein the Z attached to the propanedione at position 1 can be the same substituent as the aromatic substituent attached to the 3 position of the propanedione moiety in Formula I.
