PURPOSE: Provided is a method for coloring polymer materials using green tea leaves smashed finely. The polymer materials colored by the natural coloring matter of green tea leaves has the advantages of such as harmless of human, no-decoloration and no-discoloration by heat resistance, decay resistance and chemical resistance. CONSTITUTION: The method proceeds to such as follows: smashing the green tea leaves with a size of 75μm; and mixing the smashed green tea leaves with polymer resin with 0.1 % (wt.). |
