Claim Text:
1. A resin composition comprising an alkoxysilyl group-containing hydrogenated block copolymer [3], and a hydrocarbon-based polymer [4] having a number average molecular weight of 300 to 5000, wherein the resin composition comprises the hydrocarbon-based polymer [4] in an amount of 1 to 50 parts by weight based on 100 parts by weight of the alkoxysilyl group-containing hydrogenated block copolymer [3], the alkoxysilyl group-containing hydrogenated block copolymer [3] being obtained by introducing an alkoxysilyl group into a hydrogenated block copolymer [2] that is obtained by hydrogenating 90% or more of unsaturated bonds of the main chain, the side chain, and the aromatic ring of a block copolymer [1] that comprises at least two polymer blocks [A] and at least one polymer block [B], the polymer block [A] comprising a repeating unit derived from an aromatic vinyl compound as a main component, the polymer block [B] comprising a repeating unit derived from a linear conjugated diene compound as a main component, a ratio (wA:wB) of a weight fraction wA of the polymer block [A] in the block copolymer [1] to a weight fraction wB of the polymer block [B] in the block copolymer [1] is 30:70 to 65:35, and the hydrocarbon-based polymer [4] is a hydrogenated (co)polymer of an olefin and/or a conjugated diene that has an iodine number of 2.0 or less.
