Reaction-based laser marking compositions, systems and methods |
| 摘要 |
An ink formulation comprises a binder and at least one marking component, which comprises at least one metal oxides or oxyanion and at least one oxidizing/reducing agent, which absorbs laser irradiation between wavelengths of 780-10,600 nm, thereby causes the formulation to change color. |

1. A laser marking composition comprising
(I) a marking component comprising
(a) at least one metal oxide selected from vanadium pentoxide and copper oxide, and(b) zinc phosphate; and (II) optionally, a binder,
wherein upon irradiation in a wavelength range of between about 700 nm and 14000 nm the laser marking composition bonds to a substrate to which it is contacted. |
