FIELD: process engineering.
SUBSTANCE: invention relates to multilayer films based on polyamide-6 and like polymers and may be used for decoration of surfaces. Film incorporates polyamide-based layer I with monomer links including, at least, eight carbon atoms and layer II directly adjoining layer I and including sand blend comprising similar polyamide layer and copolymer with functional groups. Film is used for making composite material with base layer including polyamide-6, polyamide-66, polyamide-6/66 or copolyamides that represent derivatives of polyamide-6, polyamide-66, polyamide-6/66 with portion of monomer links substituted by aromatic monomer links. Note here that said composite material features high adhesion of its layers.
EFFECT: high adhesion of layers.
