(57) [Problem] To provide a vinylidene chloride-based resin coloring composition capable of sufficiently maintaining stable extrudability and high barrier properties even when coloring at a high concentration. SOLUTION: This is a coloring composition comprising a vinylidene chloride-based copolymer resin A, a pigment B, a dispersant C and a surfactant D, wherein the vinylidene chloride-based copolymer resin A is a gel permeation chromatography method. Weight average molecular weight of 50,000 to 80,000. |
