TONER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18305103 titled 'TONER
Simplified Explanation
- The patent application describes a toner composition that includes toner particles with a release agent and silica fine particles on their surface. - The presence of fragment ions corresponding to a specific D unit structure is observed during measurement. - The silica fine particles are dispersed in a mixture of ethanol and aqueous solution of NaCl, and then titrated with sodium hydroxide to obtain a specific titer range. - A specific chemical shift is obtained in the measurement, with D representing the area of a peak between -25 and -15 ppm, and D1 representing the area of a peak between -19 and -17 ppm. - The ratio between D and D1 is specific and important. - The release agent is located on the surface of the toner particles.
Original Abstract Submitted
A toner includes a toner particle including a release agent, and a silica fine particle on a surface of the toner particle. Fragment ions corresponding to a D unit structure are observed in a specific measurement; when the silica fine particle is dispersed in a mixed solution of ethanol and aqueous solution of NaCl, followed by a titration operation using sodium hydroxide a titer is within a specific range; in a chemical shift obtained by a specific measurement, with D as an area of a peak having a peak top present in a range from -25 to -15 ppm, and with D1 as an area of a peak having a peak top present in a range of more than -19 ppm and -17 ppm or less, D and D1 are in a specific ratio. The release agent is present on the surface of the toner particle.
