FUSER COMPONENT AND METHOD FOR OBTAINING IMAGE ON CARRIER Russian patent published in 2016 - IPC C09D173/00 B32B27/34 C08G73/10 G03G15/20 C08J5/18

Abstract RU 2572408 C2

FIELD: physics, photography.

SUBSTANCE: invention relates to a fuser component for use in electrophotographic apparatus, including in digital printers, as well as a method of obtaining images on a carrier using a fuser component. The fuser component comprises a main (bearing) part and an external coating layer on its surface, having a cross-linked fluorinated polyimide with a curing agent, wherein the fluorinated polyimide contains:

where Ar₁ and Ar₂ are aromatic groups containing about 6 to about 60 carbon atoms; and Ar₁ and/or Ar₂ also contain a side fluoro-group. The fluorinated polyimide has an active centre capable of reacting with the curing agent. The invention enables to obtain a full-colour image using an image-on-image technique.

EFFECT: invention enables to obtain a material with improved wear-resistance and separating properties, does not require the use of a parting lubricant, enables to produce a fuser from fewer parts and reduces the duration of production thereof.
