    摘要： A process for the manufacture of pigments comprising a coloured composition incorporated in a polycondensation resin said resin not containing aldehyde derivatives, especially formaldehyde derivatives, wherein the reactants for the formation of said polycondensation resin and the coloured composition are introduced continuously into a reactor and are mixed, the mixture travels forward in die reactor and at the end of reaction the product is withdrawn continuously from the said reactor. The process is particularly suitable for the preparation of fluorescent pigments. The reactor used is preferably an extruder.
    Also claimed are compositions comprising diketo-pyrrolo-pyrrole colourants and certain polyester or polyamide resins as well as a process for the preparation of said compositions.
