Publication number: 20030040554Abstract: A toner binder for dry toners which comprises a polyester; and a process for producing the toner binder.

However, when the two polyesters mixed differ greatly in softening point, the effect of mixing is not obtained and pigments show poor dispersibility during toner production. The toner binder and the process eliminate these problems. The toner binder comprises aggregates of binder resin particles comprising two polyesters (A) and (B), wherein the polyester (A) has a higher softening point than the polyester (B) and the polyesters (A) and (B) have been evenly mixed in each particle. The process for producing a toner binder is characterized by melt-mixing the two polyesters (A) and (B) at 80 to 180° C. The toner binder is used mainly as an ingredient for dry toners.Type: ApplicationFiled: September 13, 2002Publication date: February 27, 2003Inventors: Hideo Nakanishi, Tomohisa Kato, Masakazu Iwata

Patent number: 6270562Abstract: A filler material comprising a fibrous material and one or more forms of surface-modifying particles for use in dental composites and dental restorations. The surface-modifying particles are bonded to the fibrous material to increase the surface area of the fibrous material and improve the bonding properties of the fibrous material to enable it to better bond to a resin matrix material in a dental composite. In accordance with the present invention, the fibrous material possesses a lower melting temperature than the surface-modifying particles. The surface-modifying particles and the fibrous material are heated to a temperature below the softening temperature of the fibrous material but at a temperature and time sufficient to soften the surface of the fibrous material in order to bond the surface-modifying particles thereto.Type: GrantFiled: June 10, 1999Date of Patent: August 7, 2001Assignee: Jeneric/Pentron, Inc.Inventor: Weitao Jia
