WHITE INK COMPOSITION FOR INK-BASED DIGITAL PRINTING |
| 摘要 |
The present disclosure is directed to a white ink composition for use in digital offset printing, including a first white colorant including a first plurality of white pigment particles, wherein an average diameter of at least about 40% of the first plurality of white pigment particles is in a range of about 250 nanometers to about 350 nanometers, a second white colorant including a second plurality of white pigment particles, wherein an average diameter of at least about 40% of the second plurality of white pigment particles is in a range of about 350 nanometers to about 550 nanometers, at least one dispersant, at least one component selected from a curable monomer or a curable oligomer, and a photo-initiator. Also provided is a method of digital offset printing using the white ink composition of the present disclosure. |

1. A white ink composition for use in digital offset printing, comprising:
a first white colorant comprising a first plurality of white pigment particles, wherein an average diameter of at least about 40% of the first plurality of white pigment particles is in a range of about 250 nanometers to about 350 nanometers, a second white colorant comprising a second plurality of white pigment particles, wherein an average diameter of at least about 40% of the second plurality of white pigment particles is in a range of about 350 nanometers to about 550 nanometers, at least one dispersant, at least one component selected from the group consisting of a curable monomer and a curable oligomer, and a photo initiator. |
