1. A security material, comprising:
- a layer of laminate, the laminate having first and second sides;
a plurality of materials being used for printing on at least a first side of the layer of laminate, wherein one of said plurality of materials comprises a pearlescent material;
the plurality of materials being applied in a predetermined relationship at selected locations on at the first side of the layer of laminate so as to define a pattern,wherein the pattern comprises the pearlescent material and a design in which two differently colored pearlescent materials are interlocked to define a visually active design that conveys a varying visual image depending on the attitude of the layer of laminate relative to the viewer and permits printed information that is overlaid by the pattern to be effectively perceived.

Abstract
A security material for documents comprises a first layer of material, such as a polymeric film or laminate, having first and second sides. A pearlescent material is applied to at least one of the first and second sides. The pearlescent material defines a pattern comprising at least two different colors that are at least partially interlocked in the pattern, and the pattern permits printed information that is overlaid by the pattern to be effectively perceived.

9. A method of fabricating a security material, the method comprising:
-
providing a base layer, the base layer having first and second sides; providing a plurality of materials for printing to at least the first side of the base layer, at least one of the plurality of materials comprising a pearlescent material; applying a pearlescent material at a first location on the first side of the base layer so as to define a pattern, wherein the pattern comprises the pearlescent material and a design in which two differently colored materials are interlocked to define a visually active design conveying a varying visual image depending on the attitude of the security material relative to the viewer and permitting printed information that is overlaid by the pattern to be effectively perceived.

10. A security laminate, comprising:
-
a first layer of polymeric material, the first layer having first and second sides; and a pearlescent material applied to at least one of the first and second sides, the pearlescent material defining a pattern comprising at least two different pearlescent colors that are at least partially interlocked in the pattern, wherein the pattern permits printed information that is overlaid by the pattern to be effectively perceived. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A security laminate, comprising:
-
a base layer having first and second sides, and; means for defining an optically variable pattern on at least the first side of the base layer to provide an image having a holograph-like appearance but which does not require fabricating a hologram on the security instrument and wherein the optically variable pattern is constructed and arranged so that, when the base layer is applied over printed information, the means for defining and optically variable pattern is capable of at least partially overlaying the printed information without effectively obscuring the overlaid printed information.
