PCT No. PCT/KR92/00033 Sec. 371 Date Feb. 4, 1994 Sec. 102(e) Date Feb. 4, 1994 PCT Filed Jul. 21, 1992 PCT Pub. No. WO93/04407 PCT Pub. Date Mar. 4, 1993.The present invention relates to a process for preparing a partially crosslinked binder resin useful for electrophotographic toner, which comprises: (1) preparing a partially crosslinked polymer by way of: a non-crosslinking emulsion polymerization of an aromatic vinyl monomer, an acrylic monomer and a cyanide compound in a linear structure, and a cross-linking polymerization of an aromatic vinyl monomer, an acrylic monomer, a cyanide compound and an unsaturated carboxylic acid or an unsaturated monomer containing an epoxy group; and (2) coagulating the polymer latex obtained in step(1) in the presence of a water soluble amine.
