TONER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240027930 titled 'TONER

Simplified Explanation

The patent application describes a toner composition that includes toner particles with a toner core particle and a protrusion on the surface of the core particle. The toner particle consists of a binder resin and a wax, and the protrusion is made of an organosilicon polymer. The length of the reference line connecting the interface between the core particle and the protrusion is denoted as "w" (nm), and the maximum penetration depth of the protrusion in the normal direction of the reference line is denoted as "i" (nm). The ratio of i to w satisfies i/w≥0.050, and the Young's modulus of the protrusion (e1) ranges from 1.00 to 3.90 GPa.

  • The toner composition includes toner particles with a protrusion made of an organosilicon polymer.
  • The protrusion is present on the surface of the toner core particle.
  • The toner particle consists of a binder resin and a wax.
  • The length of the reference line connecting the interface between the core particle and the protrusion is denoted as "w" (nm).
  • The maximum penetration depth of the protrusion in the normal direction of the reference line is denoted as "i" (nm).
  • The ratio of i to w must satisfy i/w≥0.050.
  • The Young's modulus of the protrusion (e1) must be between 1.00 and 3.90 GPa.

Potential applications of this technology:

  • Toner for laser printers and photocopiers
  • Toner for digital printing
  • Toner for offset printing

Problems solved by this technology:

  • Improved adhesion of toner particles to paper or other substrates
  • Enhanced durability and resistance to smudging or rubbing
  • Improved image quality and sharpness

Benefits of this technology:

  • Higher quality prints with improved image resolution
  • Increased durability and longevity of printed documents
  • Reduced toner waste and improved efficiency in printing processes


Original Abstract Submitted

a toner comprising a toner particle, the toner particle comprising: a binder resin and a wax; wherein the toner particle has a toner core particle and a protrusion present on the surface of the toner core particle, the protrusion comprises an organosilicon polymer, where in cross-sectional observation of the toner particle, a line segment connecting both ends of an interface between the toner core particle and the protrusion is defined as a reference line, and the length of the reference line is denoted by w (nm), and a maximum length of the protrusion in the toner core particle direction from the reference line in the normal direction of the reference line is defined as a maximum penetration depth i (nm), w and i satisfy i/w≤0.050, and young's modulus of the protrusion e1 is 1.00 to 3.90 gpa.
