<p>PURPOSE:To obtain a resin composition containing uniformly dispersed pigment, without causing the lowering of the physical properties and discoloration, by adding a specific petroleum resin and a pigment to a resin selected from polyamide, etc. CONSTITUTION:100pts.wt. of a resin selected from polyamide, polyacetal, polyethylene terephthalate and polybutylene terephthalate, is compounded with 0.01- 5pts.wt. of a petroleum resin having a softening point of 70-200 deg.C and 0.01- 5pts.wt. of a pigment. Since the petroleum resin exhibits excellent diffusibility in the melt kneading with the above resins and at the same time, facilitates the dispersion of the pigment, it can be used as a dispersing agent having extremely excellent effect.</p> |
