Organic solvent-based retroreflective composition for industrial spraying

A composition selected from an organic solvent-based retroreflective ink, an organic solvent-based paint, or an organic solvent-based coating composition, wherein:

• based on the total weight of the composition, the composition consists of:
• from 25 wt. % to 75 wt. % organic solvent;
• from 1 wt. % to 74 wt. % spherical glass beads having a median particle diameter D50, as measured with laser diffraction, from 1 μm to 150 μm, and a refractive index, measured at a wavelength λ of 589 nm, from 1.5 to 2.8;
• from 0.15 wt. % to 1.2 wt. % thickener;
• and
• from 0 to 30 wt. % of one or more further ingredients;
• the composition has a first Brookfield viscosity η1 at a shear rate of 0.5 rpm of from 0.2 Pa·s to 8 Pa·s;
• the composition has a second Brookfield viscosity η2 at a shear rate of 20 rpm of from 80 mPa·s to 450 mPa·s;
• the second Brookfield viscosity η2 is less than or equal to 0.5 times the first Brookfield viscosity η1;
• and
• 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.
