2078124 9113943 PCTABS00007 The invention relates to an organic pigment, preferably an azoic pigment, characterized in that it has been treated with polyalkylene imine with a view to improving its characteristics when used in painting. This treatment can be carried out both on an organic pigment treated by known methods and on an untreated pigment. A treated pigment is generally preferred, however, particularly if maximum opacity is desired.
