SUPPORTING MATERIAL CONTAINING POLYVINYL ALCOHOL AND ITS APPLICATION IN XEROGRAPHIC LAYER-BY-LAYER BUILD-UP Russian patent published in 2021 - IPC G03G9/87 C08L29/02 C08L29/04 C08L29/06 C08L39/06 

FIELD: xerographic printing.

SUBSTANCE: invention relates to supporting materials that can be used in layer-by-layer build-up by means of xerographic printing. A particle of supporting toner material for use in xerographic layer-by-layer growth is proposed, containing a polymer of polyvinyl alcohol (PVA) and a mixture of additives containing chitosan and polyvinylpyrrolidone (PVP), wherein the amount of the additive mixture is selected to adjust the T_g of the PVA polymer within the range from about 1°С to about 20°С from the T_g of the required model toner material. Also proposed is a xerographic toner system and a method for producing a supporting toner material.

EFFECT: expansion of the range of supporting materials that can work in the context of layer-by-layer build-up using xerographic technology.
