More Information
Summary:The invention relates to an organic solvent-based retroreflective ink, paint or coating composition, having a first Brookfield viscosity η1 at a shear rate of 0.5 rpm of between 0.2 and 8 Pas and a second Brookfield viscosity η2 at a shear rate of 20 rpm that is between 80 and 450 mPa·s, with the proviso that η2 is at least 2 times lower than η1, wherein the organic solvent-based retroreflective ink, paint or coating composition consists of, based on the total weight of the composition: * 25-75 wt. % of organic solvent: * 1-85 wt. % of spherical glass beads: * 0.15 1.2 wt. % of thickener; and * 0-30 wt. % of one or more further ingredients: wherein the Brookfield viscosities η1 and η2 are measured with a #2 spindle in a 600 ml beaker having a diameter of 8.25 cm at a temperature of 25° C.
