TONER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18392903 titled 'TONER
The patent application describes a toner where a pigment is dispersed in toner particles containing a high amount of a crystalline resin, resulting in excellent low-temperature fixability and coloring power.
- Toner includes toner particles with a binder resin, pigment, and pigment dispersant.
- Binder resin contains 20.0% to 100.0% by mass of a crystalline resin.
- Pigment dispersant is a polymer with a structure interacting with the pigment and a polymer moiety interacting with the crystalline resin.
Potential Applications: - Printing industry for high-quality color printing. - Photocopiers and laser printers for improved toner performance.
Problems Solved: - Enhanced low-temperature fixability. - Improved coloring power in printing applications.
Benefits: - High-quality color prints. - Efficient toner performance in various printing devices.
Commercial Applications: Title: Advanced Toner Technology for Enhanced Printing Performance This technology can be used in commercial printing services, office printers, and manufacturing of toner cartridges for various printing devices.
Questions about Toner Technology: 1. How does the high amount of crystalline resin in the toner particles improve fixability and coloring power?
- The crystalline resin enhances the toner's ability to adhere to paper at low temperatures and improves the vibrancy of printed colors.
2. What sets the polymer pigment dispersant apart in interacting with both the pigment and crystalline resin?
- The unique structure of the polymer allows it to effectively disperse the pigment while also facilitating interaction with the crystalline resin for optimal toner performance.
Original Abstract Submitted
Provided is such a toner that a pigment is dispersed in a toner particle containing a large amount of a crystalline resin, that is, a toner excellent in low-temperature fixability and coloring power. The toner is a toner including a toner particle containing a binder resin, a pigment and a pigment dispersant, wherein the binder resin contains from 20.0% to 100.0% by mass of a crystalline resin, wherein the pigment dispersant is a polymer containing a specific structure that interacts with the pigment and a specific polymer moiety that interacts with the crystalline resin.
