TONER AND TONER PRODUCTION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240219854 titled 'TONER AND TONER PRODUCTION METHOD
The abstract describes a toner containing a binder resin with both crystalline and amorphous resins, as well as wax. The toner has a unique matrix-domain structure with crystalline resin in the matrix and amorphous resin in the domains.
- The toner has a specific monomer unit in the crystalline resin, as shown in a differential curve obtained through viscoelasticity measurements.
- The differential curve has specific minimal values within certain temperature ranges, with storage elastic moduli at these temperatures falling within specific ranges.
Potential Applications: - Printing industry for high-quality prints - Manufacturing of toner cartridges for printers
Problems Solved: - Improved print quality and durability - Enhanced performance of toner cartridges
Benefits: - Consistent and reliable printing results - Extended lifespan of toner cartridges
Commercial Applications: - Toner manufacturing companies can use this technology to produce high-quality toners for various printers, catering to a wide market of consumers.
Questions about the technology: 1. How does the unique matrix-domain structure of the toner contribute to its performance? 2. What are the specific advantages of having both crystalline and amorphous resins in the toner formulation?
Original Abstract Submitted
a toner comprises a toner particle that contains a binder resin having a crystalline resin and an amorphous resin, and a wax, wherein a matrix-domain structure made up of a matrix including the crystalline resin, and domains including the amorphous resin, is present in a cross-sectional observation of the toner, the crystalline resin has a specific monomer unit, in a differential curve, which is obtained through differentiation of a temperature-storage elastic modulus curve by temperature, with temperature being a horizontal axis and a common logarithm log gⲠof a storage elastic modulus gⲠbeing a vertical axis as obtained in a viscoelasticity measurement of the toner, the differential curve has specific minimal values p1 and p2 within specific temperature ranges, and has storage elastic moduli gⲠat the temperatures of the minimal values p1 and p2 lie in respective specific ranges.
