is the migration of a colourant from one medium to another one in contact with it. Where for example strongly coloured woods (especially exotic ones) have too much primer, their colours dissolve and seep into the base coat film - they bleed. For examples, with inlays, maple will be seen to stained around the edges by the adjacent stained wood. These materials that bleed are referred to as inhibiting ones and may delay or prevent polyester lacquers from hardening completely.



transforming dissolved materials into insoluble ones with the help of chemical reactions or physically by adding products in which the material is insoluble or difficult to dissolve
