cze	Ftalocyaninový komplex železa jako primární sikativ pro alkydové nátěrové hmoty	Tato studie popisuje účinnost železitého komplexu s ftalocyaninovým ligandem ve dvou rozpouštědlových a dvou vysokosušinových alkydových pojivech. Standardizované mechanické testy na nátěrových filmech potvrzují výrazně yšší aktivitu než v případě komerčního 2-ethylhexanoátu kobaltnatého.	alkyd; železo; primární sikativ
eng	Helmet Phthalocyaninato Iron Complex as a Primary Drier for Alkyd Paints	This study describes the catalytic performance of an iron(III) complex bearing a phthalocyaninato-like ligand in two solvent-borne and two high-solid alkyd binders. Standardized mechanical tests revealed strong activity, which appeared in particular cases at concentrations about one order of magnitude lower than in the case of cobalt(II) 2-ethylhexanoate, widespread used in paint-producing industry. The effect of the iron(III) compound on autoxidation process, responsible for alkyd curing, was quantified by kinetic measurements by time-resolved infrared spectroscopy and compared with several primary driers. Effect of the drier concentration on coloration of transparent coatings was determined by UV-Vis spectroscopy.	alkyd paints; iron; phthalocyanine; primary drier; infrared spectroscopy
