(57) Abstract: By blending a hydrogenated block copolymer with a specific structure and a liquid additive, excellent flexibility, low molecular weight retention, mechanical properties, photomelt viscosity / adhesion and liquid retention are achieved. To provide a soft composition. (A) A polybutadiene polymer block (A) having a 1,2-bond content of 5 to 25% in the block, and a weight ratio of a conjugated diene to another monomer is 1 00/0 to 50/50, and the content of the conjugated diene having an unsaturated bond in the side chain is 2 of the total conjugated diene amount in the block. 1 to 50% by weight of a hydrogenated block copolymer obtained by hydrogenating an olefinic unsaturated bond in a block copolymer having 5 to 95% by weight of a polymer block (B) in each molecule. %, And (b) a liquid additive (99 to 50% by weight). |
