FIELD: construction engineering.
SUBSTANCE: invention relates to a composite median original sheet for use in a composite laminate assembly which is intended for separation into individual cards. This sheet comprises a median substrate layer and an intermediate film layer connected with the median substrate layer. The intermediate film layer comprises a conductive material which provides a protective, decorative or functional card element. The median substrate layer and the intermediate film layer are connected to the other composite median original sheet in such a way that the assembly is produced on the layer composite. The conductive material has a low thickness within the intermediate film layer so that the intermediate film layer prevents electrostatic discharge (ESD) from being carried out through the intermediate film layer and the outside of the individual cards.
EFFECT: achieved is production of high-quality laminate assembly.
