ABSTRACT:
A colored packaging material for the photosensitive material having improved light-shielding properties and physical properties, providing a packaged photosensitive material. Colored pigment is kneaded with dispersing pigment for dissociating and dispersing the colored pigment for improving uniform dispersion of the colored pigment for providing a colored packaging material for the photosensitive material having improved light-shielding and physical properties. The colored pigment is further improved in uniform dispersion by coating the colored pigment and the dispersing pigment with a surface coating agent such as fatty acid metal salt. For producing the packaging material, a master batch method, may be used. The packaging material may be used to make a packaged photosensitive material, e.g., injection or inflation molded articles.
