摘要：
Compressed, comprising a core, a coating and one or more structures stamped or printed on an interface between said core and said coating, in which. these structures are predetermined and three-dimensional, b. These structures are not periodic, c. said structures are>； 2 mm in the lateral direction (x / y) and>； 50 nm in the vertical direction (z), d. said structures are made invisible to the naked eye by said coating, e. said structures are detectable by optical interferometry microscopy, and f. the refractive index of said coating and the refractive index of said core differs by at least 0.04 (real part n) and / or at least 0.02 (imaginary part k).Comprimido, que comprende un nucleo, un recubrimiento y una o mas estructuras estampadas o impresas en unainterfaz entre dicho nucleo y dicho recubrimiento, en el quea. dichas estructuras son predeterminadas y tridimensionales,b. dichas estructuras son no periodicas,c. dichas estructuras son >； 2 mm en direccion lateral (x/y) y >； 50 nm en direccion vertical (z),d. dichas estructuras se hacen invisibles a simple vista mediante dicho recubrimiento,e. dichas estructuras son detectables mediante microscopia de interferometria optica, yf. el indice de refraccion de dicho recubrimiento y el indice de refraccion de dicho nucleo difiere en al menos0,04 (parte real n) y/o en al menos 0,02 (parte imaginaria k).
