Abstract: Disclosed is a method for producing a paraffin wax, the method including a step of mixing an unrefined wax containing normal paraffin with a solvent of dipole term (δp) is 4 to 8 and of hydrogen bonding term (δh) is 3 to 10 of the Hansen Solubility Parameters, and obtaining a mixed liquid; and a step of separating a solid material from the mixed liquid and obtaining a paraffin wax in which the normal paraffin concentration is higher.

Abstract: A resin composition including: at least one resin ingredient selected from the group made of a resin (A) having a side chain (a) containing a hydrogen-bonding cross-linking moiety with a carbonyl-containing group and/or a nitrogen-containing heterocycle and having a glass transition point of 25° C. or lower, and a resin (B) containing a hydrogen-bonding cross-linking moiety and a covalent-bonding cross-linking moiety in a side chain and having a glass transition point of 25° C. or lower, wherein both the resin (A) and the resin (B) are a reaction product of a cross-linking agent with a maleic anhydride-modified thermoplastic resin having a melting point of 68° C. to 134° C. and a maleation rate of 0.5 to 2.5% by mass.
