    Abstract: A process for the preparation of a solid catalyst component comprising a Ti compound, a coloring agent and optionally an electron donor on a Mg chloride based support, said process comprising one or more steps (a) carried out at a temperature ranging from 0 to l50°C in which a Mg based compound of formula (MgCl m X 2-m )·nLB, in which m ranges from 0 to 2, n ranges from 0 to 6, X is, independently R 1 , OR 1 , -OCOR 1 or O-C(O)-OR 1 group in which R 1 is a C 1 -C 20 hydrocarbon group and LB is a Lewis base, is reacted with a liquid medium comprising a Ti compound having at least a Ti-Cl bond in an amount such that the Ti/Mg molar ratio is higher than 3; said process being characterized by the fact that in at least one of said steps an organic coloring agent is present either associated to the Mg compound or dispersed in said liquid medium comprising the titanium compound.
