Melamine based mannich-compounds and a process for obtaining the same

A melamine-based Mannich compound selected from the group consisting of the following formulae (7) to (11):

• wherein
• A is O,
• the moieties R1, R2 and R5 are selected from a group comprising H, non-substituted C1-C50-alkyl, non-substituted C2-C50-alkenyl, non-substituted C2-C50-alkinyl, non-substituted C3-C10-cycloalkyl, non-substituted C5-C7-cycloalkenyl, which in each case can be interrupted by one or more oxygen atoms, sulphur atoms, substituted or mono-substituted nitrogen atoms, double bonds, siloxan groups and/or by one or more groups of the type —C(O)O—, —OC(O)—, —C(O)—, —NHC(O)O—, —OC(O)NH— and/or —OC(O)O—,
• the moieties R3 and R4 are selected from a group comprising non-substituted C1-C50-alkyl, non-substituted C2-C50-alkenyl, non-substituted C2-C50-alkinyl, non-substituted C3-C10-cycloalkyl, non-substituted C5-C7-cycloalkenyl, which in each case can be interrupted by one or more oxygen atoms, sulphur atoms, substituted or mono-substituted nitrogen atoms, double bonds, siloxan groups and/or by one or more groups of the type —C(O)O—, —OC(O)—, —C(O)—, —NHC(O)O—, —OC(O)NH— and/or —OC(O)O—,
• the moiety R9 is selected from a group comprising H, substituted or non-substituted hydroxy, substituted or non-substituted amino, halogen, substituted or non-substituted C1-C12-alkyl, substituted and non-substituted C3-C7-cycloalkyl, substituted and non-substituted C2-C12-alkenyl, substituted or non-substituted aryl, whereby the substituted aryl can be bound via at least one methylene bridge to the aromatic structure and can be a group of the formula:
• wherein R9′ has the meaning of R9;
• substituted or non-substituted heteroaryl, substituted and non-substituted carbonyl, substituted and non-substituted C1-C50-alkyl, substituted and non-substituted C1-C50-alkenyl, substituted and non-substituted C1-C50-alkinyl, substituted and non-substituted C3-C10-cycloalkyl, substituted and non-substituted C5-C7-cycloalkenyl, whereby each alkyl, alkenyl and alkinyl chain, can be interrupted by one or more oxygen atoms, sulphur atoms, substituted or mono-substituted nitrogen atoms, double bonds, siloxan groups and/or by one or more groups of the type —C(O)O—, —OC(O)—, —C(O)—, —NHC(O)O—, —OC(O)NH— and/or —OC(O)O—, and whereby up to four moities R9 are present on the aromatic ring,
• and mixtures thereof.
