Abstract:
1. A method for producing colored reclaimed resin particles which comprises the steps of: mixing 100 weight parts of a pulverized thermoplastic resin product to be reclaimed with 0.01 to 20 weight parts of a white pigment and 0.01 to 20 weight parts of a colored pigment to give a mixture, wherein the pulverized thermoplastic resin product comprises carbon black and a plastic component comprising a thermoplastic resin component and an elastomer component, the carbon black being contained in an amount of not more than 2 weight parts per 100 weight parts of the plastic component, or wherein the pulverized thermoplastic resin product comprises a mixture of a pulverized resin product comprising carbon black and a plastic component comprising a thermoplastic resin component and an elastomer component, the carbon black being contained in an amount of not more than 2 weight parts per 100 weight parts of the plastic component, and a pulverized thermoplastic product containing a colored pigment, or wherein the pulverized thermoplastic resin product contains two or more different colored pigments; heating the mixture to give a molten product; and converting the molten product into solid particles having color characteristics of L*=28.00 to 68.00.
