Abstract
Disclosed is a resin composition for an exterior material of a vehicle. The resin composition may include an amount of about 40 to 90 parts by weight of polypropylene resin having a melt index of about 70 to 110 g/10 min; an amount of about 10 to 40 parts by weight of an olefin block copolymer including an ethylene-based repeating unit and a α-olefin-based repeating unit having 4 to 30 carbon atoms; an amount of about 10 to 20 parts by weight of needle-shaped inorganic filler having an aspect ratio of about 5 to 10; and an 0.01 to 5 parts by weight of laser-transmitting black colorant, wherein all the parts by weights based on 100 parts by weight of the resin composition. In particular, an average transmittance may range from about 0.01 to about 1% or less in a wavelength of about 380 to 700 nm, and an average transmittance may range from about 15% or greater and less than about 100% in a wavelength of about 800 to 1200 nm.
