These resin materials can include a polymer formed by polymerization of at least one acrylic resin having (i) a content ratio (molar ratio) of hydroxyl groups of side chains each containing 10 or more carbon atoms to hydroxyl groups of side chains each containing less than 10 carbon atoms that is less than 1/3; (ii) at least one polyol that contains plural hydroxyl groups in which all the hydroxyl groups are connected together through a chain containing 6 or more carbon atoms; and (iii) an isocyanate. The resin material can further include a polymerization ratio of about 0.1 or more and about 10 or less, the polymerization ratio being a ratio (B/A) of a total molar amount (B) of hydroxyl groups contained in all the polyols used for the polymerization to a total molar amount (A) of hydroxyl groups contained in all the acrylic resins used for the polymerization.
