Abstract
A liquid UV curable inkjet ink includes one or more photoinitiators, an organic colour pigment, and a polymerizable composition containing at least one monofunctional polymerizable compound and at least one polyfunctional polymerizable compound, wherein the organic colour pigment is present in an amount of 6.0 to 13.0 wt % based on the total weight of the liquid UV curable inkjet ink; the at least one polyfunctional polymerizable compound is present in an amount of at least 20.0 wt % based on the total weight of the polymerizable composition; and the UV curable inkjet ink has a viscosity at 45° C. and a shear rate of 10 s−1 of at least 16.0 mPa.s.
Claims15
A liquid UV curable inkjet ink comprising:
- one or more photoinitiators in an amount of at least 7.0 wt % relative to a total weight of the liquid UV curable inkjet ink;
- an organic color pigment;
- and
- a polymerizable composition in an amount less than 75 wt % relative to the total weight of the liquid UV curable inkjet ink and including at least one monofunctional polymerizable compound and at least one polyfunctional polymerizable compound;
- wherein
- the organic color pigment is present in an amount of 6.0 to 13.0 wt % based on the total weight of the liquid UV curable inkjet ink;
- the at least one polyfunctional polymerizable compound is present in an amount of 20.0 wt % to 50.0 wt % based on a total weight of the polymerizable composition;
