Abstract: A glass fiber reinforced resin composition is described, comprising the following components: (a) 30 to 98 parts by weight of a crystalline propylene polymer; (b) 2 to 30 parts by weight of a glass fiber having an average diameter of 10.mu. or less, the amount of a binder deposited being from 0.01 to 0.3% by weight; (c) 0 to 35 parts by weight of an ethylene-based rubber; (d) 0 to 30 parts by weight of at least one inorganic filler selected from talc, mica, calcium silicate and glass powder; and (e) 0 to 10 parts by weight per 100 parts by weight of the sum of the components (a) to (d) of a pigment comprising a coloring component and a dispersing component, the proportion of a coloring matter or matters having a Mohs hardness of 3.5 or more in the coloring component being less than 30% by weight. This composition is superior in high temperature stiffness, appearance, and pelletizability, and is satisfactory in an amount of warp of article or re-heating warp, and impact strength.
