Abstract (en)
[origin: WO2021028466A1] The present invention relates to a method for producing an effect pigment paste comprising at least steps (1) and (2), namely producing a mixture containing at least one effect pigment (a) and at least one polymer (b) in a liquid medium (c) (step (1)), and dispersing the mixture obtained after step (1) to obtain the effect pigment paste (step (2)), wherein step (2) is performed using a vibrator, and the effect pigment paste obtained after the performance of step (2) has ended is free from grinding media. The invention also relates to an effect pigment paste which can be produced by means of this method and contains an amount of effect pigment of at least 5% by weight based on the total weight of the effect pigment paste, and to a use of a vibrator for dispersing effect pigments in order to produce an effect pigment paste, the effect pigment paste obtained after the dispersion has ended being free from grinding media.
