    Abstract: A lignin composition containing two or more compounds represented by the following formula (1), where the total content of the compounds is 0.06% by mass or more:




    where in the formula, Ra is a hydrogen atom, a methyl group, an ethyl group, a furyl group, a hydroxymethylfuryl group, a hydroxyphenyl group, a hydroxymethoxyphenol group, or a hydroxydimethoxyphenol group; Rc1 and Rc2 are independently a hydroxyl group, an alkoxy group, an amino group, or a thiol group; R11 to R20 are independently a hydrogen atom, a hydroxyl group, a hydrocarbon group including 1 to 15 carbon atoms, a hydrocarbon ether group including 1 to 15 carbon atoms, or a group containing a carbonyl group.

    Abstract: Provided is a rubber composition that allows for manufacturing a tread rubber that is high in braking performance on a dry surface road and also high in braking performance even on a wet road surface such as a manhole surface that is slipperier than an asphalt road surface. The rubber composition is prepared by compounding a rubber component (A) including a natural rubber by 70 mass % or more, and by further compounding, with the rubber component as 100 parts by mass: (B) at least one kind of thermoplastic resins selected from among C5-based resins, C5- to C9-based resins, C9-based resins, terpene-based resins, terpene-aromatic compound-based resins, rosin-based resins, dicyclopentadiene resins, and alkylphenol-based resins, at 5 parts by mass to 50 parts by mass; and (C) a filler including silica, at 20 parts by mass to 120 parts by mass, in which the filler (C) contains silica by 50 mass % to 100 mass %.
