ARTICLE

摘要

An article comprises a substrate (2) including a structure (3) for generatin g an optically variable effect. The substrate is par- tially provided with an indicia receptive coating (5) such that at least par t of the optically variable effect (3) remains visible. Possi- ble optically variable effects include diffraction, interference and polarisation effects. These effects are generally visible in white light. A method of manufacturing articles comprises providing a substrate (2 ) which includes a structure (3) for generating opti- cally variable effects. A partial continuous indicia receptive coating (5) i s provided on the substrate (2) such that at least part of the optically variable effect remains visible. An article manufactured in th is way may receive security printing (6) on the indicia receptive coating.
