Abstract
An object of the present invention is to provide a hydrogenated copolymer composition and the like having an excellent balance among initial tack strength, suppression of increase in tackiness, and suppression of uneven thicknesses of a tacky layer. The object can be achieved with the following hydrogenated copolymer composition. A hydrogenated copolymer composition comprising: a component (a) comprising a polymer block comprising a vinyl aromatic monomer unit as a main component and a polymer block comprising a conjugated diene monomer unit as a main component; and a component (b) comprising a polymer block comprising a vinyl aromatic monomer unit as a main component and a polymer block comprising a conjugated diene monomer unit as a main component.
