Title:
光学的に可変なセキュリティ要素
Document Type and Number:
Japanese Patent JP7292005
Kind Code:
B2
Abstract:
The present invention relates to an optically variable security element for securing valuable articles, having a substrate having opposing first and second main surfaces and, arranged on the first main surface, an optically variable pattern that comprises an embossing pattern and a coating. The coating comprises at least one imprinted line grid and a background layer that contrasts with the line grid. The embossing pattern comprises a two-dimensional grid of elevated and/or depressed embossing elements. Both are combined in such a way that substantially on every embossing element lies at least one line segment of a line in the line grid, and at least one of the parameters position of the line segment on the embossing element, orientation of the line segment on the embossing element and form of the line segment varies location dependently across the dimension of the optically variable pattern. Due to the line grid, a movement effect, especially a pump or rotation effect, is created when the security element is tilted.
