Abstract
In a printed article, pigment flakes are magnetically aligned so as to form curved patterns in a plurality of cross-sections normal a continuous imaginary line, wherein radii of the curved patterns increase along the imaginary line from the first point to the second point. When light is incident upon the aligned pigment flakes from a light source, light reflected from the aligned pattern forms a bright image which appears to gradually change its shape and move from one side of the continuous imaginary line to another side of the continuous imaginary line when the substrate is tilted with respect to the light source.
Claims14
An article, comprising:
- a substrate coated with a magnetic ink comprising magnetic flakes that have been aligned in a magnetic field to form an image on an imaged surface;
- wherein the image includes two bowed, oblong ovals each having an inner region within a curved bright line perimeter that is brighter than the inner region, each of the bowed, oblong ovals having two ends;
- wherein each of the curved bright line perimeters of the oblong ovals increase in intensity upon a tilt of the article, and if the image is viewed at a normal angle, each of the curved bright line perimeters appears as two offset curved bright line perimeters, and if the image is viewed at a tilt, each of the two offset curved bright line perimeters appears as a single curved bright line perimeter;
- and
- wherein the image further includes an obelisk shape between the bowed, oblong ovals, the obelisk shape having a base region and a tip region, a first of the two longitudinal ends of each oval being proximate the base region and a second of the two ends of each oval being proximate the tip region.
An article, comprising:
- a substrate coated with a magnetic ink comprising magnetic flakes that have been aligned in a magnetic field to form an image;
- wherein the image includes at least two curved bright lines separated one from another;
- wherein the at least two curved bright lines increase in intensity upon a tilt of the article;
- wherein if the image is viewed at a normal angle, each of the at least two curved bright lines appears as offset curved bright lines, and if the image is viewed at a tilt, each of the offset curved bright lines appears as a single curved bright line;
- and
- wherein each of the at least two curved bright lines intersects with a chord of a circle to form a first portion of a circle and a second portion of a circle.
An article, comprising:
- a substrate coated with a magnetic ink comprising magnetic flakes that have been aligned in a magnetic field to form an image;
- wherein the image includes four pie-shaped wedges, each pie-shaped wedge including a curved bright line forming an outer arc;
- wherein the curved bright lines of the four pie-shaped wedges combine to form a 360° perimeter around a center point of the image;
- and
- wherein the 360° perimeter increases in intensity upon a tilt of the article, and if the image is viewed at a normal angle, the 360° perimeter appears as two offset perimeters, and if the image is viewed at a tilt, the two offset perimeters appear as a single 360° perimeter.
