Abstract

A composition may contain a wide variety of particles with good dispersibility, the composition being able to make both rigidity and elongation at sufficient levels compatible with each other even under a low humidity. A coating and a film may each be formed of such a composition, and a base material having the foregoing coating or film. Specifically, the composition may contain an ethylene-vinyl alcohol copolymer (A) having the content of an ethylene unit of 0.5 to 19 mol % relative to all structural units and a particle (B), wherein the content of the particle (B) is 1 part by mass or more and less than 100 parts by mass based on 100 parts by mass of the ethylene-vinyl alcohol copolymer (A).
