Abstract: The present invention relates to an asphalt mixture including aggregates, a polyamide resin and asphalt, wherein the polyamide resin has a softening point of from 60 to 150° C., and is compounded in an amount of from 3 to 90% by mass on the basis of a total amount of the polyamide resin and the asphalt; and a paving method using the asphalt mixture. The asphalt mixture of the present invention provides a pavement which is free from rutting and torsional breakage and exhibits a high oil resistance. The pavement obtained from the asphalt mixture is free from fracture and can be prevented from suffering from occurrence of rutting and torsional breakage even when leakage of oils over a surface of the pavement occurs.

Abstract: The present invention provides a nonaqueous pigment dispersant containing a copolymer having: (a) a constituent unit derived from a nitrogen atom-containing polymerizable macromonomer having an ethylenic unsaturated double bond at one terminal, and (b) a constituent unit derived from a monomer unit having an ethylenic unsaturated double bond, being copolymerizable with the nitrogen atom-containing polymerizable macromonomer of constituent (a), and a pigment dispersion composition containing the dispersant, a pigment and a nonaqueous solvent.

Abstract: A hair cosmetic composition comprising fine particles of a crosslinked polymer, which are insoluble in water and ethanol and do not form a film at normal temperature, is disclosed. A conventionally known film-forming polymer may also be formulated optionally. The hair cosmetic is free from stiffness, stickiness, or excessive gloss imparted to the hair which are the defects of conventional hair cosmetics using only conventional film-forming polymers, and provides excellent hair conditioning and hair-resetting effects.

Abstract: A hair preparation comprises an oil-absorptive polymer of a vinyl monomer having a solubility parameter of 7 to 10, said polymer being porous and having a squalene absorption of at least 1 ml/g. It may further contain an anti-dandruff agent. The hair preparation may also comprise an anti-dandruff agent and a different oil-absorptive substance.

Abstract: An electrophotographic toner composition, improved in uniform dispersion therein of carbon black and electrophotographic properties, comprises a binder polymer, carbon black and a compound selected from the group consisting of a sulfonate compound having the formula (I), an alkaline earth metal salt of a basic alkylphenol persulfide having the formula (II), an alkyl or alkenyl succinic acid imide having the formula (III-1) or (III-2), an alkyl salicylic acid salt having the formula (IV), a compound having the formula (V) and a product obtained by treating the compound (V) with sulfur, in which R, R', R1 and R2 are a substituent and M is an alkaline earth metal.
