1. An aminoketone compound comprising the structure of a 1,3-propane-dione, of general Formula I:

OG Complex Work Unit Chemistry
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.
