Patent ID: 7851540

Claim:
A resin composition consisting essentially of 100 parts by weight of an ethylene/1-butene random copolymer (a), 10 to 500 parts by weight of at least one styrene block copolymer (b), 10 to 140 parts by weight of an oil (c) relative to 100 parts by weight of the total amount of (a) and (b), and 0 to 500 parts by weight of a polypropylene resin (d) relative to 100 parts by weight of the total amount of (a) and (b), wherein ethylene/1-butene random copolymer (a) contains 1-butene in an amount of 8 to 25% by mol, and the ratio (MFR 10 /MFR 2 ) of MFR 10 measured under a load of 10 kg and MFR 2 (also described as MFR) measured under a load of 2.16 kg, both being measured at 190° C. according to ASTM D-1238, and the molecular weight distribution (Mw/Mn) of the ethylene/1-butene random copolymer (a) satisfy the relationship: Mw/Mn+ 4.63 ≦MFR 10 /MFR 2 ≦14 −2.9 Log( MFR 2 ).
