<p>The disclosed colored resin composition contains 90% to 99.9% by mass of a polypropylene-based resin satisfying the conditions (a) to (d) described below, and 0.1% to 10% by mass of a coloring agent (wherein the total amount of the polypropylene-based resin and the coloring agent is 100% by mass). The polypropylene-based resin is a reactive polypropylene prepared by polymerization of an ethylene/C3-10 a-olefin copolymer rubber in the presence of a homo polypropylene or a random polypropylene in a reactor, and satisfies the following conditions: (a) the melt flow rate (at a temperature of 230°C and under a load of 21.6 N) is at least 4 g/10 minutes; (b) the low-temperature brittle temperature is at most 0°C; (c) the total light transmittance measured using a 1-mm-thick test specimen is at least 25%; and (d) the melting peak temperature is at least 140°C.</p> |
