Zusammenfassung:	To provide a primer coating composition that is particularly excellent in both of adhesion to a CFRP substrate and adhesion to a topcoat composition.SOLUTION: The inventive primer coating composition is a two-part primer coating composition containing a base agent and a curing agent. The base agent contains a modified bisphenol A type epoxy resin, prepared by modifying bisphenol A type epoxy resin, and a chelate-modified epoxy resin. The base agent and/or the curing agent contain/contains at least an extender pigment as a pigment, the extender pigment including at least talc and dolomite.SELECTED DRAWING: None 【課題】本開示は、特にＣＦＲＰ基材との密着性及び上塗り組成物との密着性の双方に優れるプライマー塗料組成物を提供することを目的とする。【解決手段】本発明に係るプライマー塗料組成物は、主剤と硬化剤とを含有する２液系のプライマー塗料組成物において、主剤が、ビスフェノールＡ型エポキシ樹脂を変性させた変性ビスフェノールＡ型エポキシ樹脂とキレート変性エポキシ樹脂とを含有し、主剤若しくは硬化剤のいずれか一方又は両方は、顔料として少なくとも体質顔料を含有し、体質顔料は少なくともタルクとドロマイトとである。【選択図】なし
