Curable inkjet inks radiation, flexible and scratch resistant

摘要

Curable inkjet ink by free radical radiation containing a photoinitiator and compuestospolimerizables including a) no more than 15% by weight of one or more monofunctional acrylates whose homopolymer has a value of Tginferior at 20 ° C, b) at least 45% by weight of a monomer mixture consisting of: b1) 10 to 45% by weight of an N-vinyl lactam and / or vinylether acrylate, and b2) 10 to 45% by weight of an ethoxylated polyacrylate and / or propoxylated having a molecular weight of at menos450, wherein all weight percents are based on the total weight of the inkjet ink, and wherein the Tg value is determined by the DSC method as defined in ISO 11357-2: 1999.
