Polymeric sheeting materials directly thermally printed upon with a thermal punting system and a resin-based colorant/binder. The polymeric sheeting materials comprise a core sheet and a thermally print receptive surface on the core sheet. The thermally print receptive surface may be formed from compositions comprising a polyurethane dispersion. The thermally print receptive surface is smooth, transparent, durable, and weatherable. Signage articles made from the polymeric sheeting materials of the invention may be configured to have the desired combination of frangibility, durability, retroreflectivity and/or low production cost. Frangible, retroreflective signage articles may be produced from the polymeric sheeting materials and may have durable variable information thermally and variably printed directly on the articles.
