TONER AND TONER PRODUCTION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18543153 titled 'TONER AND TONER PRODUCTION METHOD
The patent application describes a toner that contains a binder resin with both crystalline and amorphous resins, as well as wax, creating a unique matrix-domain structure within the toner particles.
- The toner particles have a matrix-domain structure consisting of a matrix with crystalline resin and domains with amorphous resin.
- The crystalline resin in the toner has specific monomer units, as shown in a differential curve obtained through viscoelasticity measurements.
- The differential curve of the toner shows specific minimal values within temperature ranges, indicating unique properties of the toner material.
Potential Applications: - Printing industry for high-quality and durable prints - Manufacturing of toner cartridges for laser printers and photocopiers
Problems Solved: - Improved print quality and longevity - Enhanced performance of toner cartridges
Benefits: - Crisp and clear prints - Longer-lasting toner cartridges - Consistent performance in various printing conditions
Commercial Applications: Title: Advanced Toner Technology for High-Quality Printing This technology can be used in the production of toner cartridges for commercial printers, photocopiers, and other printing devices, catering to businesses and individuals seeking superior print quality and durability.
Questions about the technology: 1. How does the unique matrix-domain structure of the toner particles contribute to print quality? - The matrix-domain structure ensures even distribution of toner on the printing surface, resulting in sharp and consistent prints.
2. What advantages does the presence of both crystalline and amorphous resins in the toner binder provide? - The combination of crystalline and amorphous resins offers a balance of rigidity and flexibility, enhancing the durability and performance of the toner.
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.
