Abstract: A non-aqueous, substantially solvent-free and photoinitiator-free, particle beam curable ink having a viscosity less than 30 m Pa—s at 60° C., comprising: (i) a colorant; and (ii) a mixture of (meth)acrylate compounds; wherein: (a) the colorant is present in the ink in an amount of 0.1 to 14.9% by weight relative to the total weight of ink; and (b) the mixture of (meth)acrylate compounds comprises c % of one or more mono (meth)acrylate compounds, d % of one or more di (meth)acrylate compounds and e % of one or more compounds having three or more (meth)acrylate groups, wherein the values of c %, d % and e % are by weight relative to the total weight of the mono (meth)acrylate compounds, di (meth)acrylate compounds and compounds having three or more (meth)acrylate groups and are such that the value of Formula (1) is less than or equal to 60: c ? ? ? % + 0.

Abstract: Non-aqueous, radiation-curable inks comprising pigment, dispersant and a liquid carrier, wherein the pigment has an acid value greater than 8 mg of NaOH per gram of pigment. The inks are particularly suitable for use in ink jet printers.
