Abstract: An injection molded colored article produced from colored material prepared by blending a coloring pigment with a synthetic resin. The article has the shape of a long main body section and a thin plate section integrally molded along a side edge of the main body section. A back surface of the main body has a curve formed from an inner end thereof. The thin plate section is formed into a tapered shape, having its thickness decreased toward its outer edge. An inclined angle .theta. defined between a upper surface and a back surface of said thin plate section, a ratio of distance A between an inner edge of said upper surface and an outer edge of said thin plate section to a distance B between said inner end of said back surface of said thin plate section and said outer edge, A/B, and a thickness C of said main body section are selected to fall within the following ranges;5.ltoreq..theta..ltoreq.45.degree.;0.3.ltoreq.A/B.ltoreq.1; and1.5.ltoreq.C.ltoreq.10 mm.
