The dispersion effect of acrylate copolymer binder consisted of butyl acrylace(BA) and acrylic acid (AA) on red pigment cake PR48:2 was studied. The results showed that the best dispersion could be obtained as the stirring time over 3 h, ω(AA)=40% and ω(BPO)=2%, the red value in colour three stimuli characterisation of the dispersion film was 66, higher than that from pigment powder(44). The dispersion of pigment press cake showed higher colour strength, and the pigment kept better colour characteristic.
