ABSTRACT:
A color masterbatch resin composition for a packaging material for a photographic photosensitive material which does not adversely affect photographic properties of the photographic photosensitive material, comprising a light-shielding material in a concentration thrice as much as or more that of the packaging material for a photographic photosensitive material, and a thermoplastic resin of which 50 wt. % or more is the same type as a thermoplastic resin occupying 50 wt. % or more of the total thermoplastic resin composing the packaging material for a photographic photosensitive material, production thereof, a packaging material for a photographic photosensitive material formed of a color masterbatch resin composition, and production thereof. In the color masterbatch resin composition and the packaging material for a photographic photosensitive material of the invention, hight-shielding material is dispersed uniformly by employing a special resin composition, and thereby, adverse affects upon photographic photosensitive materials are prevented, and favorable appearance can be ensured. Moreover, fog with time, abnormal sensitivity, abrasion, pressure marks, etc. can be prevented.
