Abstract
A colored base composition comprising a dispersing amphoteric resin and pigment, said amphoteric resin being prepared by the addition or condensation reaction of an acidic resin bearing both of an electron acceptant group and a functional group and a basic resin and/or basic low molecular weight compound bearing both of an electron donative group and a functional group, the functional group located on one side of the reactants being an active hydrogen and/or active alkoxyl group and the functional group located on the other side of the reactants being a group which is reactive with said active hydrogen and/or active alkoxyl. This base composition is quite stable, compatible with various kinds of resins and pigments and capable of producing a paint composition with excellent film performance.
