Abstract

An image is disclosed comprised of flakes in a carrier, such as an ink vehicle or a paint that can be aligned in a magnetic field. The flakes are aligned so as to produce one or more kinematic features such as a rolling bar that appears to move as the image is tilted. These images can provide security features on high-value documents, such as bank notes.

Claims

1. An image printed on a substrate comprising:

a non-rectangular closed region coated with aligned pigment flakes, wherein said flakes are aligned so as to produce a kinematic object therewithin, wherein the kinematic object appears to move across the closed region as the image is tilted or the position of the light source upon the image is varied, and wherein the area of the kinematic object changes as it appears to move across the region, or wherein the kinematic object appears to move horizontally and vertically simultaneously as the kinematic object appears to move.

2. An image as defined in claim 1, wherein the kinematic object is appears lighter as it appears to move, than surrounding flakes, and wherein the closed region has a curved side.

3. An image as defined in claim 1, wherein the kinematic object appears darker than surrounding flakes as it appears to move.

4. An image as defined in claim 1, wherein the kinematic object is a first rolling bar.

5. An image as defined in claim 4, including a second rolling bar.

6. An image as defined in claim 5, wherein the first and second rolling bars appear to move in different directions as the image is tilted or when viewed from a different direction.

7. An image as defined in claim 1, wherein the kinematic object is a rolling bar or rolling hemisphere and wherein the object changes in size as it appears to move when the image is tilted.

8. An image as defined in claim 1, wherein the image has a second closed region, and wherein the second closed region includes a coating having aligned pigment flakes.

9. An image as defined in claim 1, wherein the non-rectangular closed region represents an object capable of casting a shadow, and wherein the kinematic object within the object provides shading and a perception of depth and movement which increases recognition of the object.

10. An image as defined in claim 9, wherein the closed region has one or more curved lines the kinematic object follows the one or more curved lines as it appears to move.

11. An image printed on a substrate as defined in claim 1, wherein the aligned pigment flakes for producing the kinematic object are oriented in an arching configuration within the non-rectangular closed region, and wherein a second kinematic object is produced within the image, wherein flakes within the second kinematic object are oppositely arching.

12. An image printed on a substrate comprising:

a non-rectangular closed region coated with aligned pigment flakes, wherein said flakes are aligned so as to produce a kinematic object therewithin, wherein the kinematic object appears to move across the closed region as the image is tilted or the position of the light source upon the image is varied, and wherein the area of the kinematic object changes in size as the object appears to move across the region, or wherein the object appears to move horizontally and vertically simultaneously as the kinematic object appears to move.

13. An image printed on a substrate, the image comprising:

a plurality of magnetic pigment flakes in a carrier wherein a portion of the plurality of magnetic flakes are aligned in an arching pattern relative to a surface of the substrate so as to create a contrasting bar across the image appearing between a first adjacent field and a second adjacent field, the contrasting bar appearing to move relative to the first adjacent field and the second adjacent field as the image is tilted, wherein a plurality of magnetic flakes are aligned in a pattern so as to create a double contrasting bar across the image as the image is tilted.

14. An image printed on a substrate comprising:

A first region coated with aligned pigment flakes, wherein said flakes are aligned so as to produce a first kinematic object therewithin, and a second region coated with aligned pigment flakes, wherein said flakes are aligned so as to produce a second kinematic object therewithin, wherein the first and second kinematic objects appear to move in different directions simultaneously as image is tilted.

15. An image as defined in claim 14, wherein the first and second kinematic objects are rolling bars, and wherein the rolling bars move in opposite directions as the image is tilted.

16. A kinematical image of a three-dimensional object capable of casting a shadow, comprising a plurality of pigment flakes filling a region to form at least a portion of the image, wherein pigment flakes within the region are aligned so as to form a rolling bar, and wherein the rolling bar provides shading and depth to the image of the three dimensional object, wherein the shading appears to move as light source upon the image is varied.

17. A perspective image of an object, wherein at least one region of the perspective image has alignable pigment flakes within a carrier coated upon a substrate formed into a rolling bar or rolling hemisphere, for providing shading on the object.

18. A perspective image of an object as defined in claim 17, wherein one portion of the image has a rolling hemisphere, and another portion of the image has a rolling bar.

19. A method of forming an image having a kinematic hemisphere or inverted hemisphere comprising the steps of providing a dome-shaped or inverted dome-shaped magnetic field;

providing a substrate with a coating of magnetically alignable pigment flakes;

disposing the coated substrate within the dome-shaped or inverted dome-shaped magnetic field;

relatively rotating the coated substrate and the dome-shaped or inverted dome-shaped magnetic field; and

allowing the coating to cure.

20. A method of forming an image, comprising the steps of:

coating a substrate with coating of pigment flakes, and before the coating cures, exposing the coating to varying magnetic field, by moving the substrate within a magnetic field, or by varying a magnetic field permeating the coating.
