The invention relates to a method for providing a composition selected from the group consisting of organic solvent-based pastes, inks, paints and coating formulations with retroreflective properties, said method comprising the steps of: (a) providing an organic solvent-based paste, ink, paint or coating formulation without retroreflective properties; (b) providing a retroreflective organic solvent-based composition consisting of, based on the total weight of the retroreflective organic solvent-based composition: * 10 - 49.85 wt.% of organic solvent; * 50 - 85 wt.% of spherical glass beads having a median particle diameter D50, as measured with laser diffraction, between 1 and 1500 [mu]m, and a refractive index, measured at a wavelength [lambda] of 589 nm, between 1.5 and 2.8; * 0.15 - 3.5 wt.% of thickener; and * 0 - 10 wt.% of one or more further ingredients; (c) mixing the organic solvent-based ink, paint or coating formulation without retroreflective properties provided in step (a) with the retroreflectiv
