Paint set giving laminated coating film with excellent interlayer adhesion

摘要

PROBLEM TO BE SOLVED: To provide a coating material set for providing a laminated coating film having excellent interlayer adhesion between a top coating layer and an undercoating layer by using an adhesion improver for an amine curable epoxy resin coating material capable of imparting good interlayer adhesion by preventing adhesion inhibition by amine brushing.SOLUTION: There is provided a coating material set comprising an undercoating material [I] and a top coating material [II], wherein the undercoating material [I] is an amine curable epoxy resin coating material to which a (co)polymer, comprising a (meth)acrylate ester unit represented by the general formula [wherein, Rrepresents a hydrogen atom or a methyl group and Rrepresents a branched alkyl group having 3 to 18 carbon atms], is added, and the top coating material [II] is a conventional coating material as a top coating material, such as an acrylic urethane coating, for an amine curable epoxy resin coating material.SELECTED DRAWING: None
