TONER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240231249 titled 'TONER

The patent application describes a toner containing a binder resin with an amorphous polyester and a crystalline polyester.

• The binder resin in the toner exhibits specific endothermic or exothermic peaks in DSC curves, derived from the crystalline polyester.
• The DSC curves show distinct peaks during temperature changes, indicating the presence of the crystalline polyester in the binder resin.
• The patent application specifies a relationship between the temperatures of the maximum peak tops of the endothermic peaks in the DSC curves obtained through different processes.

Potential Applications:

• This technology can be used in the development of toners for various printing applications.
• It may find applications in industries requiring precise temperature control during processes involving polyester resins.

Problems Solved:

• Provides a method to analyze and characterize toners containing a binder resin with specific polyester compositions.
• Offers a way to determine the presence and behavior of crystalline polyesters in toner formulations.

Benefits:

• Enhanced understanding of toner composition for improved printing quality.
• Potential for developing toners with tailored properties based on binder resin composition.

Commercial Applications:

• "Innovative Toner Binder Resin Composition for Enhanced Printing Quality and Performance"

Questions about the technology: 1. How does the presence of both amorphous and crystalline polyesters in the binder resin impact the overall performance of the toner? 2. What are the potential implications of the specific endothermic or exothermic peaks derived from the crystalline polyester in the DSC curves for toner functionality and quality?

Original Abstract Submitted

provided is a toner containing a binder resin, wherein the binder resin contains an amorphous polyester and a crystalline polyester, and wherein, when the toner is used as a sample in differential scanning calorimetry (dsc) involving a first process of increasing a temperature from 20� c. to 180� c., a second process of decreasing the temperature from 180� c. to 20� c., and a third process of increasing the temperature from 20� c. to 180� c., dsc curves have a specific endothermic peak or exothermic peak derived from the crystalline polyester, and when a temperature of a maximum peak top of the endothermic peak in the dsc curve obtained through the first process is represented by t1 (� c.), and a temperature of a maximum peak top of the endothermic peak in the third dsc curve is represented by t2 (� c.), the tl and the t2 satisfy the following expression (1).
