Summary: | The invention relates to dry toner particles comprising at least a radiation curable resin and a colouring agent, the radiation curable resin comprises a blend of a) an (meth)acrylated epoxy/polyester resin b) (meth)acrylated polyurethane resin. Preferably, when fused and cured toner images obtainable from said dry toner particles are obtained on a substrate used for developing same, these images have an equivalent rub number (ERN)>6, wherein ERN=MEK rub resistance/(radiation dose*meq/gr), wherein meq/gr designates the milli-equivalent amount of double bounds per gram of said radiation curable resin and a viscosity behaviour such that the viscosity at 140° C. is lower than the viscosity at 120° C. |
