Sustainable thermal paper formulation using lignocellulosic biomass fractions.

ABSTRACT: Thermal paper presents widely recognized health hazards due to its formulations containing bisphenol A (BPA) and bisphenol S (BPS) as color developers with limited research on safer alternatives. Here, we introduce sustainable thermal paper formulations built with functionalized lignin polymers and lignin-derived esters, combined with a sensitizer derived from xylan. Light-colored lignin polymer was obtained via sequential aldehyde-assisted fractionation, which reduced chromophore concentration through multiple extraction cycles. Good performance was achieved with polymeric lignin (color density at 120°C ≈ 0.8 to 1.1) when combined with xylan-derived diformylxylose (DFX), each of which is produced directly by simple biomass fractionation. Coatings remained stable for over a year under ambi
