The problem of misting in printing inks may be cured by using as the oligomer in an energy-curable printing ink a radiation-curable acrylate-modified aminoamide resin which is the Michael addition product of a polyol ester having at least two (meth)acrylate ester groups with an aminoamide thermoplastic polymer, the aminoamide thermoplastic polymer being the reaction product of a polyamine with an acid component which comprises a polymerised unsaturated fatty acid and a C2 - C22 fatty acid, from 1 to 25% of the acid functionality forming the aminoamide polymer being said C2 - C22 fatty acid, the resin being liquid at 25~C.
On peut résoudre le problème de la voltige des encres d'imprimerie si on utilise en tant qu'oligomère d'encre d'imprimerie durcissant sous l'effet de l'énergie, une résine d'aminoamide à modification acrylate durcissante au rayonnement, qui consiste en un produit d'addition de Michael d'un ester de polyol possédant au moins deux groupes ester de méthacrylate avec un polymère thermoplastique d'aminoamide. Ce dernier est le produit de la réaction d'une polyamine avec un constituant acide comprenant un acide gras insaturé polymérisé et un acide gras C2 - C22, 1 à 25 % de la fonctionnalité acide constituant le polymère d'aminoamide étant ledit acide gras C2 - C22, la résine étant liquide à 25 °C.
