PHOTOCURABLE SLURRY
To provide a photocurable slurry that has excellent long-term stability, can photocrosslink of inorganic particles in the slurry with a trace amount of monomer, and allows for stable dispersion of the inorganic particles in the slurry.SOLUTION: A photocurable slurry includes (1) inorganic particles, (2) a modified polyethyleneimine in which a compound with a polyethylene glycol chain is added to a polyalkyleneimine or a polyethyleneimine, (3) a polyfunctional acrylate, (4) a photopolymerization initiator, and (5) a nonaqueous solvent with a vapor pressure of 50 Pa or less at 20°C.SELECTED DRAWING: Figure 4
【課題】長期安定性に優れ、スラリー中の無機物粒子間をごく少量のモノマー分で光架橋することが可能で、スラリー中の無機物粒子の分散安定性に優れる光硬化性スラリーを提供する。【解決手段】（１）無機物粒子と、（２）ポリアルキレンイミン、または、ポリエチレンイミンにポリエチレングリコール鎖を持つ化合物が付加した構造の変性ポリエチレンイミンと、（３）多官能アクリレートと、（４）光重合開始剤と、（５）２０℃での蒸気圧が５０Ｐａ以下である非水系溶媒と、を含む光硬化性スラリー。【選択図】図４
