<P>PROBLEM TO BE SOLVED: To provide a resin composition with preferable initial adhesiveness by injection molding without the need of pre-molding treatment such as primer coating to a flat surface of a metal such as steel plate and aluminum, further with adhesiveness being long durability and high-temperature durability, as well as high modulus of elasticity. <P>SOLUTION: This resin composition includes (1) a polyester, (2) a fibrous reinforcing material, (3) a spherical reinforcing material, (4) a polyolefin, (5) an epoxy compound, and (6) a tackifier, in weight ratios of (1)/(2)/(3)/(4)/(5)/(6)=100/10-100/1-40/1-60/1-40/1-40, where the polyester (1) has a polyetherdiol with 500-4,000 number-average molecular weight copolymerized by 5-50 mol% to the whole glycol component. <P>COPYRIGHT: (C)2013,JPO&INPIT |
