Battelle Memorial Institute

Contact BMI About This Technology

Technology Marketing SummaryA bio-based resin and toner formulation for photocopier and laser printer toners – resins containing soy derived chemicals and protein were developed and have appropriate electrical charging and melting or fusing properties to hold the pigments onto the paper fibers during the xerographic or dry printing process.DescriptionThe technology also was shown to be more effective at deinking or removing print from the paper during the recycling process than the conventional petroleum-based resins and toners.Benefits
  • Increased use of bio-based components and reduction of petrochemicals
  • Drop-in replacement for conventional petroleum toners
  • Simplified and lower energy recycling process to generate secondary paper fibers
Applications and Industries
  • Resin for dry electrostatic printing (e.g. photocopiers and laser printers)
  • Adaptable to produce color concentrates as additive packages for polymer formulations
