INK OR PAINT COMPOSITION COMPRISING A HYPERBRANCHED ANIONIC POLYESTERAMIDE AND A COMBINATION WITH A SUBSTRATE COMPRISING A HYPERBRANCHED CATIONIC POLYESTERAMIDE

摘要

An ink or paint formulation, but in particular an ink formulation, which comprises a hyperbranched polyesteramide is described and claimed. In particular, the formulation will comprise (i) a colorant, (ii) a hyperbranched polyesteramide and (iii) a solvent. The hyperbranched polyesteramide used is suitably chemically "matched" to a coating in the substrate to which the formulation is to be applied, so that they bond together strongly, and combinations of formulations and substrates are also claimed.
