Pigment preparation for coloring polymers
View Patent ↗The invention relates to a pigment preparation for coloring polymers. The inventive preparation comprises one or more pigments and a carrier. According to the invention, the carrier includes an oligomer or a combination of low-molecular-weight polymers from the group containing polymers and copolymers of ethylene-acrylic acid, ethylene-maleic anhydride or polypropylene-maleic anhydride. The carrier also includes a polymer from the group containing polymers of ethylene-ethyl acrylate, ethylene/butyl acrylate, ethylene/methacrylic acid, polypropylene with grafted methyl polymethacrylate, polypropylene with grafted polystyrene or block copolymers of styrene. For organic pigments, the preparation contains 50%-70% pigment and 50%-30% carrier. For inorganic pigments, the preparation contains 60%-90% pigment and 40%-10% carrier. The invention comprises a polyvalent pigment preparation which can be used in the production of color concentrates with specific bases and high precision.
