INK COMPOSITION FOR USE ON NON-ABSORBENT SURFACES |
| 摘要 |
According to one aspect, an ink composition includes a colorant, one or more polymers such as a polyurethane siloxane, a surfactant, water, and a solvent. The ink composition has a total solids content of less than about 20% by weight. Further the ink has an initial surface tension of less than about 50 dynes per centimeter on application and the surface tension on drying should not increase by more than 20 percent. |

1. An aqueous ink comprising:
from about 3 to about 15% by weight of one or more polymers; from about 0.5 to about 12% by weight of one or more colorants; from about 5 to about 35% by weight of a solvent; from about 0.03 to about 1.0% by weight of a pH modifier; and from about 50 to about 80% by weight of water, wherein the aqueous ink has a viscosity from about 1 to about 20 mPa-s such that the aqueous ink can be applied to a non-absorbent surface in a layer. |
