Abstract:
A black colored reinforced polyamide resin composition consisting essentially of the following components (A) to (D):(A) a polyamide comprising:(a1) from 85-100% by weight of a semiaromatic polyamide having a crystallization temperature of not higher than 210.degree. C. and containing an aromatic ring in its monomer constituting unit; and(a2) from 0 to 15% by weight of an aliphatic polyamide having a crystallization temperature of not higher than 210.degree. C.;(B) at least one inorganic filler selected from the group consisting of glass fiber, mica, talc, kaolin and wollastonite;(C) a carbon black; and(D) at least one copper-phthalocyanine derivative represented by the following formula (I) and (II):CuPc-(--X--NR.sub.1 R.sub.2).sub.n (I)CuPc-(--SO.sub.2 --NR.sub.3 R.sub.4).sub.n (II)wherein CuPc represents a copper-phthalocyanine residue, X represents --CH.sub.2 --, --CH.sub.2 --CH.sub.2 --COO--C.sub.2 H.sub.4 -- or --CH.sub.2 --CH.sub.2 --COO--C.sub.3 H.sub.6 --, R.sub.1, R.sub.2 and R.sub.3 each independently represents a hydrogen atom, an unsubstituted alkyl group, a substituted alkyl group, a cycloalkyl group, an alkylaryl group, an aryl group, an alkoxyalkyl group or a heterocyclic residue, R.sub.4 represents an alkylaryl group, an aryl group, an alkoxyalkyl group or a heterocyclic residue, wherein R.sub.1 and R.sub.2 or R.sub.3 and R.sub.4 may be bonded to each other to form a substituted or unsubstituted heterocyclic ring, and n is from 1 to 4 on the average,wherein the composition contains: from 30 to 70 parts by weight of (A); from 70 to 30 parts by weight of (B); from 0.05 to 10 parts by weight of (C) based on 100 parts by weight of the total weight of (A) and (B); and from 5 to 100 parts by weight of (D) based on 100 parts by weight of (C).
