Abstract (en)

[origin: WO2022125104A1] Non-phenolic direct thermal recording media have a thermally responsive layer containing a leuco dye and a plurality of non-phenolic developers including 1,3-diphenyl urea (DPU) and urea urethane (UU ). This chemistry enables multi-purpose recording materials capable of withstanding multiple different types of environmental conditions or agents — such as a water soak, contact with polyvinyl chloride meat wrapping film, boiling water, dry and humid heat, sunlight, and. contact with hand, sanitizer. The unique non-phenolic chemistry allows the product's thermally responsive layer to have an ultra-low coat, weight, less than 1.48 g/m2.
