Aluminum acetoacetate compounds, the production and use thereof as printing ink additives

A composition comprising:

• (A) one or more aluminium compounds with three ligands per aluminium atom of the following kind:
• wherein:
• R is a C1- to C12-hydrocarbon residue, which may comprise 1 to 4 ether linkages and/or one hydroxy group, and
• R′ and R″, independent of one another, are selected from the group consisting of H, one C1- to C4-hydrocarbon residue and mixtures thereof, and
• (B) at least one glycol ether compound of the following structure:
• R′″—O—(X—O)n—H
• wherein:
• R′″ is a C1- to C18-hydrocarbon residue,
• n is an integer of 1 to 10, and
• X is a saturated substituted or unsubstituted C1- to C6-hydrocarbon, which may be linked at
• any carbon atom and may be different for each n, and
• the glycol ether compound (B) is contained in the composition in at least 5% by weight, relative to the sum of the components (A) and (B) in the composition.
