Abstract

Diffractive microstructure comprising micro-protrusions or microgrooves or a combination thereof and method of producing the same. The microstructure is formed in a layer of a thermoplastic carbohydrate polymer or a polymer derived from a carbohydrate material, said polymer having a glass transition point of less than 210 ºC. The thermoplastic polymer is preferably selected from the group of native starch, dextrin, native hemicellulose, native cellulose, poly(lactic acid), polylactides, polycaprolactone, starch derivatives, dextrin derivatives, hemicellulose derivatives, cellulose derivatives, and mixtures thereof. The invention provides an inexpensive and reliable way of incorporating into the products safety markings, which allow for visual inspection or detection, such as holograms and barcodes.
