A method for producing a resin composition, comprising the step of: subjecting a radical copolymerization of a first radical polymerizable monomer which is free from any crystalline molecular chain, and a second radical polymerizable monomer having a crystalline molecular chain, in the presence of a radical polymerization initiator, wherein the second radical polymerizable monomer is the following compound, and n n n n n n n n n n (wherein R 1 denotes a hydrogen atom or a methyl group, and R 2 denotes an alkyl group having at least 17 carbon atoms) the first radical polymerizable monomer has a particular reactivity ratio. |
