摘要： The present invention provides an inkjet ink comprising: 5-40% by weight of an N-vinyl monomer selected from N-vinyl caprolactam, N-vinyl pyrrolidone, N-vinyl piperidone, N-vinyl carbazole, N-vinyl formamide, N-vinyl indole, N-vinyl imidazole, N-vinyl acetamide, and mixtures thereof, based on the total weight of the ink; one or more difunctional monomers in which the only radiation-curable functional groups present in the monomer are (meth)acrylate groups; 9% or less by weight of a monofunctional monomer, other than the N-vinyl monomer, together with a multifunctional monomer, based on the total weight of the ink; a radical photoinitiator; and a colouring agent. The present invention also provides a method of inkjet printing using the inkjet ink of the present invention and use of an N-vinyl monomer selected from N-vinyl caprolactam, N-vinyl pyrrolidone, N-vinyl piperidone, N-vinyl carbazole, N-vinyl formamide, N-vinyl indole, N-vinyl imidazole, N-vinyl acetamide, and mixtures thereof to increase the cure speed of an inkjet ink comprising one or more of difunctional monomers.
