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.
