Abstract: front page image
(EN)Provided is a toner-use polyester resin that comprises a framework derived from an alcohol component and a framework derived from a carboxylic acid component, the alcohol component containing an aliphatic alcohol which is at least trivalent, and the toner-use polyester resin fulfills the following expressions (1)-(3). 4,000 ≤ weight-average molecular weight (Mw) ≤ 25,000 ... Expression (2) 0.5 ≤ (quantity of aliphatic alcohol which is at least trivalent) ≤ 6.5 ... Expression (3) The quantity of aliphatic alcohol which is at least trivalent in expression (1) and expression (3) is the mol% of the aliphatic alcohol that is at least trivalent with respect to the total amount of the alcohol component.
(FR)Cette invention concerne une résine polyester à usage de toner qui comprend un squelette dérivé d'un composant alcool et un squelette dérivé d'un composant acide carboxylique, le composant alcool contenant un alcool aliphatique qui est au moins trivalent, et la résine polyester à usage de toner satisfaisant les expressions (1)-(3) suivantes. Expression (1) 4000 ≤ poids moléculaire moyen en poids (Mw) ≤ 25 000... Expression (2) 0,5 ≤ (quantité d'alcool aliphatique qui est au moins trivalent) ≤ 6,5... Expression (3) La quantité d'alcool aliphatique qui est au moins trivalent dans l'expression (1) et l'expression (2) est le pourcentage molaire d'alcool aliphatique qui est au moins trivalent par rapport à la quantité totale du composant alcool.
