PROBLEM TO BE SOLVED: To obtain the subject composition sufficiently securing the high-frequency sealability as an important characteristic of the film therefrom even in the case of mass-produced products, and sufficiently preserving its stable extrudability and high-level barrier property by including a specific vinylidene chloride-based copolymer resin and others. SOLUTION: This composition for coloring use is obtained by including (A) 4-93 wt.% of a vinylidene chloride-based copolymer resin with a weight- average molecular weight of 5,000-80,000 determined by gel permeation chromatography, (B) 5-80 wt.% of a pigment, (C) 0.5-15 wt.% of a dispersant (pref. a kind of wax 50-120 deg.C in melting point and 5-500 cPs in melt viscosity at 140 deg.C) and (D) 1-50 wt.% of an acrylic resin (pref. with a glass transition temperature Tg of 40-100 deg.C).
