ABSTRACT:
The invention relates to a data carrier (1) having microencapsulated scents and to a method for producing it. The data carrier (1), which is generally made of an unabsorptive material, is in particular a telephone card, identity card or the like. The microencapsulated scents are applied to the data carrier (1) with a coating material in a mixture ratio or layer thickness such that at least some of the microcapsules (4) are accessible on the surface of the coating. After being applied to the data carrier (1) the coating material hardens by polymerization or another chemical reaction. The coating material is applied as a priming layer (5) or/and as an information layer (2) or/and as a transparent cover layer. Application takes place on one or both sides of the data carrier (1) over part of the area or all over.
