Title
(EN) POLYESTER RESIN FOR TONER BINDER, PROCESS FOR PRODUCING THE RESIN, AND TONER PREPARED THEREFROM
(FR) RESINE POLYESTER UTILISEE COMME LIANT POUR TONER, PROCEDE POUR PRODUIRE LA RESINE ET TONER OBTENU AVEC CELLE-CI
Abstract
(EN)
A polyester resin used as a binder for a toner which is excellent in offset resistance and low-temperature fixation, can keep electrostatic charge stability even under high-temperature and high-humidity conditions, has an excellent durability, and can provide clear images. It is produced by linking cross-linked low-molecular-weight polyester molecules at least part thereof through a dicarboxylic acid as a linking agent.
(FR)
On utilise une résine polyester comme liant pour toner, qui présente une excellente résistance en offset et une excellente fixation à basse température, qui peut garder stable la charge électrostatique même dans des conditions de température et d'humidité élevées, qui a une excellente durabilité et qui permet de fournir des images claires. Elle est produite en liant, au moins partiellement, des molécules réticulées de polyester à bas poids moléculaire, à l'aide d'un acide dicarboxylique utilisé comme agent de liaison.
