THERMAL PRINT RECEPTIVE AND FRANGIBLE RETROREFLECTIVE POLYMERIC SHEETINGS

摘要

Polymeric sheeting materials directly thermally printed upon with a thermal prin ting system and a resin-based colorant/binder. The polymeric sheeting materials comprise a core sheet and a thermally print recepti ve surface on the core sheet. The thermally print receptive surface may be formed from compositions comprising a polyurethane dispersion. Th e thermally print receptive surface is smooth, transparent, durable, and weatherable. Signage articles made from the polymeric sheeting mate rials of the invention may be configured to have the desired combination of frangibility, durability, retroreflectivity and/or low pr oduction 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.
