Retroreflective sheeting articles comprising a colorless thermal mass transferred image, methods of thermal mass transfer printing substrate such as polymeric films with a colorless thermal mass transferable composition, and thermal mass transfer ribbon articles comprising a colorless thermal mass transferable composition are described. The thermal mass transfer composition comprises a homogeneous unreactive thermoplastic composition comprising at least one acrylic resin and less than 3 wt-% of components that are opaque at ambient temperature.

Colorless thermal mass transfer compositions and articles

Retroreflective sheeting is described comprising a viewing surface and a non-viewing surface and a thermal mass transferred image disposed in the optical path of the viewing surface wherein the thermal mass transferred image comprises a homogeneous unreactive thermoplastic composition. In one embodiment, the unreactive thermoplastic composition comprises at least one acrylic resin and at least one colorant, wherein the composition has less than 3 wt-% of components that are opaque at ambient temperature. The percent maximum diffuse luminous transmittance to total luminous transmittance of the composition is less than 50%.
