| 摘要 | This invention relates to a printing ink and in particular to an ink for ink-jet printing which is cured by irradiation. The ink comprises at least one radiation-curable monomer; at least one passive thermoplastic resin; at least one radical photoinitiator; and at least one colouring agent; wherein the ink has a viscosity of less than 100 mPas at 25° C., and wherein the at least one passive resin is present at 2 to 15 wt % based on the total weight of the ink and has a molecular weight of 1,500 to 70,000. | ||

| 主权项 | 1. An ink-jet ink substantially free of water and volatile organic solvents consisting essentially of at least one radiation-curable monomer, wherein the radiation-curable monomer is a monofunctional monomer and the ink contains no more than 15 wt % of multifunctional monomers based on the total weight of the ink; at least one passive thermoplastic resin; 4-10% by weight of at least one radical photoinitiator based on the weight of the ink; and at least one dispersible pigment; wherein the ink has a viscosity of less than 100 mPas at 25° C., wherein the at least one passive resin is present at 2 to 15 wt % based on the total weight of the ink and has a weight-average molecular weight of 1,500 to 70,000. | ||
