Abstract
The coloring problem of a conventional molded article is overcome while retaining the advantages of high strength and high flame retardancy of the molded article when a metal hydroxide is used in combination with red phosphorus and carbon powder in the method of imparting a synthetic resin with flame retardancy. The molded article can be colored in any color and exhibits decreased lowering of electric insulation resistance when submerged. The molded article comprises a base material colored from dark red to black containing 100 wt parts synthetic resin, 5-200 wt parts metal hydroxide, 1-30 wt parts red phosphorus and 0.1-30 wt parts carbon powder; and a skin layer laminated thereon masking a colored surface of the base wherein the skin layer contains 100 wt parts, 0-100 wt parts pigment, and 0-200 wt parts metal hydroxide, provided that the total amount of pigment and metal hydroxide in the skin layer is at least 0.001 wt parts.
