摘要

GV1479 FUSIBLE ELECTROSTATICALLY ATTRACTABLE TONER A toner composition consisting of electrostatically attractable fusible powder particles, wherein said composition has an average particle site in the range of 1 to 100 .mu.m and a melt viscosity at 190.degree.C in the range of 23 to 200 Pa.s, said toner composition comprising a colouring substance and consisting for more than 50 % by weight of the total toner particle composition of a copolymer of : (1) styrene or styrene homologue. (2) an alkyl acrylate or alkyl methacrylate monomer of which the alkyl chain comprises at least 8 carbon atoms in straight line, and (3) a crosslinking monomer containing at least two ethylenically unsaturated groups.
