TONER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18339875 titled 'TONER
Simplified Explanation
The abstract describes a magnetic toner that consists of toner particles containing a magnetic body, a crystalline resin A, and an amorphous resin B. The toner composition includes 6.2 to 77.0 mass % of crystalline resin A and a total of 30.0 mass % or more of crystalline resin A and amorphous resin B. The crystalline resin A contains a monomer unit (a) and the amorphous resin B contains a monomer unit (b). The content of monomer unit (a) in crystalline resin A is 50.0 to 100.0 mass %. The SP values of crystalline resin A and amorphous resin B, denoted as SPA and SPB respectively, should satisfy the condition 0.15≤SPB−SPA≤2.00.
- The toner particles in this magnetic toner contain a magnetic body, crystalline resin A, and amorphous resin B.
- The toner composition includes 6.2 to 77.0 mass % of crystalline resin A and a total of 30.0 mass % or more of crystalline resin A and amorphous resin B.
- Crystalline resin A contains a monomer unit (a) and amorphous resin B contains a monomer unit (b).
- The content of monomer unit (a) in crystalline resin A is 50.0 to 100.0 mass %.
- The SP values of crystalline resin A and amorphous resin B, denoted as SPA and SPB respectively, should satisfy the condition 0.15≤SPB−SPA≤2.00.
Potential Applications
- Magnetic toners can be used in various printing and copying applications.

Original Abstract Submitted
A magnetic toner comprising a toner particle, the toner particle comprising a magnetic body, a crystalline resin A, and an amorphous resin B. The crystalline resin A has a monomer unit (a). The amorphous resin B has a monomer unit (b). A content of the crystalline resin A in the toner is 6.2 to 77.0 mass %. The sum of contents of the crystalline resin A and the amorphous resin B in the toner is 30.0 mass % or more. A content of the monomer unit (a) in the crystalline resin A is 50.0 to 100.0 mass %. Using SPA [(J/cm)] for a SP value of the crystalline resin A and using SPB [(J/cm)] for a SP value of the amorphous resin B, SPA and SPB satisfy 0.15≤SPB−SPA≤2.00.
