Polypropylene composition showing a good affinity for dispersion dyes and containing an isotactic polypropylene basic polymer and at least a copolyamide as dyeability additive, characterized in that it: a) comprises 80 to 99 % isotactic polypropylene basic polymer; b) comprises 1 to 10 % copolyamide component, consisting of the polycondensation products of at least two materials from the group, formed by: lactams, containing 6 to 12 carbon atoms, aminocarbonic acids, containing 6 to 12 carbon atoms, and equimolar quantities of a diamine, containing 4 to 12 carbon atoms, and a diprimary carbonic acid with 6 to 36 carbon atoms; and c) comprises 0 to 10 % ethylene/vinyl acetate (EVA) copolymer which contains 18-33 % (calculated on the basis of the EVA copolymer) vinyl acetate units, whereby all % are weight percentages.
