Abstract

The invention provides an adhesive resin composition for a toner and a manufacturing method of the adhesive resin composition. The adhesive resin composition is obtained by reaction of (1) carboxyl saturated polyester resin A, (2) hydroxyl saturated polyester resin B and (3) a compound or a polymer C which can be subjected to chain extension reaction or cross-linking reaction with polyester resinA or polyester resin B, wherein an acid value of the polyester resin A is within 25 to 75 mgKOH / g; a hydroxyl value of the polyester resin B is within 25 to 55 mgKOH / g; and the resin or the compound Ccan be epoxy resin or compound, polyhydroxyalkyl amide, closed polyisocyanate, amino resin and the like. The manufacturing method of the adhesive resin composition comprises the following steps of continuously conveying a melt with A, B and C components into a single-axis horizontal continuous reactor as shown in the figure according to the proportion, and continuously carrying out chain extension reaction or cross-linking reaction at the reaction temperature of 200 to 220 DEG C for 20 to 30 minutes.

Description

technical field [0001] The present invention relates to an adhesive resin composition for electrostatic image developing toner (toner) used in office equipment such as electrostatic copiers and laser printers, and a method for producing the adhesive resin composition. Background technique [0002] Electrophotography is widely used in modern office equipment such as copiers, laser printers, fax machines, and all-in-one machines. The electrophotography method is to form an electrostatic latent image on the surface of the photoreceptor; then develop the latent image with toner to form a toner image on the surface of the photoreceptor; and then transfer the toner image by electrostatic force in the copying step paper copy paper; finally in the fusing step, the toner image is fused by a heated fuser roller, and the image is fixed on the copy paper. [0003] With the further high-speed and energy-saving of modern office equipment such as copiers, printers, fax machines and multi-...
