Abstract
The present invention provides coating compositions for marking substrates, which comprises a color former, an amine salt of an organic metal compound, a binder, a solvent, and optionally additional components, wherein the amine salt of the organic metal compound is of formula (I) in which X is silicon or boron, and E and F are the same or different and are selected from the group consisting of a, b, c, d, e, f, g, h in which R6 and R7 are the same or different are hydrogen, C1-4-alkyl, C1-4-alkoxy, halogen, amino or carboxy, and for X=silicon o=1 and p=0, and R1 is aryl, aralkyl or C1-4-alkyl, or o=1 and p=1, and R1 and R2 together form a one residue selected from the group consisting of a, b, c, d, e, f, g and h, and for X=boron o=0 and p=0, and R3, R4 and R5 are the same or different and are hydrogen, C1-12-alkyl, C1-6-hydroxyalkyl, allyl, aralkyl or arylsulfonyl, in which aralkyl or arylsulfonyl can be substituted with C1-4-alkyl, or R3 and R4 together with the nitrogen to which they are attached form a morpholino or piperidino ring. The present invention also provides a process for the preparation of the composition of the present invention, substrates coated with these compos…
