A particulate chromatic resin composition comprises an unused thermoplastic resin component, a chromatic pigment and a white pigment, or a particulate white resin composition comprises an unused thermoplastic resin component, a white pigment and a black pigment, in which a sheet made from resin composition shows a relationship between a lightness and a light transmittance satisfying the following condition:1300&#x2266;()&#x2266;4000wherein L* means a lightness of a sheet of 3 mm thick having been made of the resin composition, and B means a total light transmittance in terms of % of a sheet of 50 &#x3bc;m thick having been made of the resin composition.

Particulate chromatic resin composition

[Problems] To produce a resin composition from a waste plastic material composed of a major portion of a thermoplastic resin and a small amount of incompatible solid foreign material. [Means for solving problems] A reclaimed resin composition which is produced by mixing a pulverized waste plastic material containing a major portion of a thermoplastic resin and a small amount of a non-thermoplastic solid foreign material with a light-shielding component and a light-shielding filler to give a mixture and melting the mixture under heating, and a sheet made from which shows a relationship between a lightness and a light transmittance satisfying the following condition:()&#x2266;4000wherein A means a lightness of a sheet of 3 mm thick having been made of the reclaimed resin composition, and B means a total light transmittance (%) of a sheet of 50 &#x3bc;m thick having been made of the resin composition.
