| 摘要 |
This invention provides an inkjet ink comprising :an α,&bgr;-unsaturated ether monomer in which the only radiation-curable functional groups present in the monomer are α,&bgr;-unsaturated ether groups;a tri- or higher functionality (meth)acrylate monomer in which the only radiation-curable functional groups present in the monomer are acrylate groups; and a colouring agent;wherein the ink contains less than 5% by weight of water and volatile organic solvents in total, and less than 10% by weight of mono-and di-functional monomers in total, other than the α,&bgr;-unsaturated ether monomer, where the amounts by weight are based on the total weight of the ink, and wherein the ink has a viscosity of less than 100 mPas at 25ºC. The ink is particularly suitable for printing onto food packaging. |
