Zusammenfassung:	Provided are: a coating agent which has excellent adhesion to various substrates including an olefin-based substrate and is for imparting gas barrier properties; a laminate having excellent gas barrier properties obtained by using the coating agent, and a packaging material. The coating agent includes a resin (A) and an aqueous solvent (B), wherein the resin (A) comprises a vinyl alcohol-based polymer (A1) and a polyalkyleneimine (A2), the laminate has a gas barrier coating layer comprising the coating agent, and the packaging material comprises the laminate. L'invention concerne : un agent de revêtement qui a une excellente adhérence à divers substrats comprenant un substrat à base d'oléfine et qui est destiné à conférer des propriétés de barrière aux gaz ; un stratifié ayant d'excellentes propriétés de barrière aux gaz obtenues à l'aide de l'agent de revêtement, et un matériau d'emballage. L'agent de revêtement comprend une résine (A) et un solvant aqueux (B), la résine (A) comprenant un polymère à base d'alcool vinylique (A1) et une polyalkylèneimine (A2), le stratifié ayant une couche de revêtement barrière contre les gaz comprenant l'agent de revêtement, et le matériau d'emballage comprenant le stratifié. オレフィン系基材を含む種々の基材への密着性に優れ、ガスバリア性を付与するためのコーティング剤、当該コーティング剤を用いて得られるガスバリア性に優れる積層体、包装材を提供する。樹脂（Ａ）と、水性溶剤（Ｂ）とを含み、前記樹脂（Ａ）がビニルアルコール系重合体（Ａ１）と、ポリアルキレンイミン（Ａ２）とを含むコーティング剤、当該コーティング剤からなるガスバリアコーティング層を有する積層体、当該積層体からなる包装材。
