TONER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18339830 titled 'TONER
Simplified Explanation
The patent application describes a toner composition that includes toner particles made of a binder resin. The binder resin contains a specific type of crystalline resin called resin A, which is made up of a monomer unit with a specific structure.
- The toner's viscoelasticity is measured, and the temperature at which the storage elastic modulus G' of the toner is 1.0×10Pa is denoted as T1 (°C).
- The ratio of the loss elastic modulus G" of the toner to the storage elastic modulus G' of the toner at temperature T1 (°C) is represented as tan δ(T1).
- The tan δ value at a temperature T1-10 (°C) is represented as tan δ(T1-10).
- The T1, tan δ(T1), and tan δ(T1-10) must satisfy a specific relationship.
Additionally, the toner particles contain a linear fatty acid metal salt with a valency of 2 or more.
Potential Applications
- This toner composition can be used in various printing applications, such as laser printers, photocopiers, and digital printing presses.
Problems Solved
- The toner composition provides improved viscoelasticity properties, which can result in better print quality and performance.
- The inclusion of the linear fatty acid metal salt enhances the toner's properties, such as adhesion and durability.
Benefits
- The toner composition with the specific crystalline resin and linear fatty acid metal salt can lead to sharper and more vibrant prints.
- The improved viscoelasticity properties of the toner can enhance the printing process and reduce issues like smudging or streaking.
