Summary:To provide a composition for primer layer formation capable of forming a primer layer capable of obtaining excellent adhesion to a phosphor layer.SOLUTION: A composition for primer layer formation for forming a primer layer adjacent to a phosphor layer of an optical laminate contains a polyfunctional compound and a curing agent, where the polyfunctional compound has a functional group A having reactivity or intermolecular force bondability to a curable resin used for the phosphor layer and a functional group B which is the same as or different from the functional group A and has reactivity to the curing agent, at the terminal of a main chain or a side chain of a resin skeleton, the functional group B contains at least one functional group selected from the group consisting of a hydroxyl group, a vinyl group, an acryloyl group, a methacryloyl group, a silanol group, an amino group and a carboxyl group, and the curing agent contains an isocyanurate type compound.SELECTED DRAWING: None 【課題】蛍光体層に対する優れた密着性が得られるプライマー層を形成することができるプライマー層形成用組成物を提供すること。【解決手段】光学積層体の蛍光体層に隣接するプライマー層を形成するためのプライマー層形成用組成物であって、多官能性化合物と硬化剤とを含有し、上記多官能性化合物は、樹脂骨格の主鎖又は側鎖の末端に、上記蛍光体層に用いられる硬化性樹脂に対して反応性又は分子間力結合性を有する官能基Ａと、上記官能基Ａと同一又は異なる、上記硬化剤に対して反応性を有する官能基Ｂとを有し、上記官能基Ｂは、水酸基、ビニル基、アクリロイル基、メタクリロイル基、シラノール基、アミノ基及びカルボキシル基からなる群より選択される少なくとも一種の官能基を含み、上記硬化剤はイソシアヌレート型化合物を含む、プライマー層形成用組成物。【選択図】なし
