ABSTRACT:
By combination of a resin exhibiting a melt viscosity of 10.sup.5 cp at a temperature of T.sub.1 and a melt viscosity of 0.5.times.10.sup.5 cp at a temperature of T.sub.2, said temperatures satisfying the following relationships:
T.sub.1 =100.degree.-150.degree. C., and .vertline..DELTA.T.vertline.=.vertline.T.sub.1 -T.sub.2 .vertline.=5.degree.-30.degree. C., and at least one of yellow, magenta and cyan colorants having specific structures, a color toner for electrostatic copying excellent in overlapping characteristic, spectral reflection characteristic, transparency, charging characteristic, durability, etc. can be obtained.
