Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:
1. A retroreflective composition comprising:
- a non-volatile matrix material;
- a volatile constituent;
- a plurality of retroreflective microsphere beads; and
- a quantity of pigment particles having a diameter of not greater than 2 microns; said quantity of pigment particles being sufficient to enable a substrate to which the composition has been applied to reflect color from the pigment particles under daytime conditions;
- wherein the volume of said matrix material to the volume of said retroreflective microsphere beads plus said pigment particles is in the range of 50% to 185%.
