Abstract
A security article may include a substrate. The security article may include a layer of security ink. The layer of security ink may include a set of color-shifting interference particles. The security article may include a layer of magnetic color-shifting ink. The layer of magnetic color-shifting ink may include a set of magnetically aligned magnetic particles. A color-shifting property of the layer of security ink and a color-shifting property of the layer of magnetic color-shifting ink may have a threshold level of similarity to create a color matching effect.
Claims20
A security article, comprising:
- a layer of security ink,
- the layer of security ink including a set of color-shifting interference particles;
- and
- a layer of magnetic color-shifting ink,
- the layer of magnetic color-shifting ink including a set of magnetically aligned magnetic particles,
- while at a first orientation of the security article, the layer of security ink being configured to appear as substantially a same color as a first portion of the layer of magnetic color-shifting ink, and
- while at a second orientation of the security article, the layer of security ink being configured to appear as substantially a same color as a second portion of the layer of magnetic color-shifting ink, and the first portion being configured to appear brighter or darker than the second portion,
- wherein the first portion is different from the second portion.
A security article, comprising:
- a substrate;
- a first layer of ink printed onto a first region of the security article;
- and
- a second layer of ink printed onto a second region of the security article,
- the second region being non-overlapping with the first region,
- the first layer of ink and the second layer of ink being non-overlapping,
- the second layer of ink including a set of magnetically aligned magnetic particles that are aligned with a direction of a magnetic field, and
- a color-shifting property of the first layer of ink and a color-shifting property of the second layer of ink being configured to create a color matching effect,
- wherein, while at a first orientation of the security article, the first layer of ink and a first portion of the second layer of ink are configured to create the color matching effect, and
- wherein, while at a second orientation of the security article, the first layer of ink and a second portion of the second layer of ink are configured to create the color matching effect.
A security article comprising:
- a dynamic feature comprising:
- a first layer of ink, and
- a second layer of ink printed on the first layer of ink;
- and
- a static feature comprising a third layer of ink,
- wherein the static feature includes a color-shifting security feature,
- wherein the color-shifting security feature surrounds at least a portion of the dynamic feature, and
- wherein the dynamic feature and the static feature are non-overlapping.
