Abstract
The present invention relates to improvements in security elements for use in or on security substrates. The security element comprises a first light transmitting carrier substrate and at least two regions of material extending substantially parallel to each other along at least a part of the length of the security element. A transverse gap of at least 1 mm lies between the regions of material. The security element further comprises an infill layer which at least partially fills the transverse gap between the regions of material. The infill layer transmits light, such that a layer located on an opposing side of the infill layer from the viewing side is visible through the infill layer when the security element is viewed in transmitted light.
