FIELD: chemistry.
SUBSTANCE: invention relates to coating agents. Disclosed is a polyol-containing coating agent which contains a polyol component obtained via polymerisation of aliphatic oligocarbonate polyols with number-average molecular weight of 200-5000 g/mol (1-50 wt %) and hydroxy-functional polyacrylate polyols (50-99 wt %), as well as one or more (poly)isocyanate cross-linking agents capable of reacting with hydroxyl groups and having average NCO-functionality ≥2.0.
EFFECT: agent enables to obtain coating with higher scratch resistance, acid resistance and resistance to solvents of finishing varnish systems.
