FIELD: chemical or physical processes; manufacturing technology.
SUBSTANCE: invention relates to a toner composition and a method for production thereof. Composition contains (a) a first amorphous polyester resin containing a polyester obtained from a dodecenyl succinic acid, a dodecenyl succinic anhydride or a combination thereof, where the first amorphous polyester is obtained by catalytic polymerisation of organic diol monomers, organic diacid and dodecenyl succinic acid, dodecenyl succinic anhydride or a combination thereof; (b) a second amorphous polyester resin containing a polyester obtained from a dodecenyl succinic acid, a dodecenyl succinic anhydride or a combination thereof and a branching agent obtained from a polyacid or polyol component, where the second amorphous polyester is obtained by catalytic polymerisation of organic diol monomers, organic diacid, dodecenyl succinic acid, dodecenyl succinic anhydride or a combination thereof and a branching agent; (c) a crystalline polyester resin; (d) wax and (e) optionally a dye.
EFFECT: technical result is obtaining an economical and environmentally friendly toner composition.
