发明名称 STRUCTURE ARRANGEMENT HAVING AN OPTICAL-DIFFRACTION EFFECT
摘要 In order to improve a structure arrangement comprising a plurality of portions having a relief structure with an optical- diffraction effect, in particular for visually identifiable optical security elements for value-bearing documents, for example banknotes, credit cards, passes or cheque documents, or other articles to be safeguarded, in such a way that it can give a viewer an image impression which in particular is more homogenous and more brilliant than is possible with known structure arrangements, it is proposed that a predominant number of the portions is of strip or band configuration.</SDOAB >
