MASTERBATCH RESIN COMPOSITION FOR COLORING POLYOXYMETHYLENE RESIN AND COLORED POLYOXYMETHYLENE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a masterbatch resin composition for coloring a polyoxymethylene resin that has less uneven coloring and superior heat stability, and reduces generation of gaseous formaldehyde, and to obtain a colored polyoxymethylene resin composition using the same.;SOLUTION: This masterbatch resin composition comprise (D) a hindered phenol antioxidant with a molecular weight of ≥400 of 0.01-10 pts.wt. and (E) an aliphatic acid metal salt of 0.01-5 pts.wt. on the basis of the total of 100 pts.wt. of (A) a polyoxymethylene resin of 99-0 wt%, (B) a quatercopolymer of nylon 6/66/610/12 of 0.5-60 wt% and (C) a colorant of 0.5-40 wt% selected from an inorganic pigment, an organic pigment and an extender.;COPYRIGHT: (C)2005,JPO&NCIPI
