PHOTOPOLYMERIZABLE COMPOUNDS AND PHOTOCURABLE COMPOSITIONS

摘要

A process for preparing photopolymerizable photosensitizing compounds which comprises addition reacting a specific benzophenone derivative with an alkylene oxide to obtain a hydroxyl group-containing reaction product which is then esterified with an unsaturated carboxylic acid or addition reacted with glycidyl acrylate; the photopolymerizable photosensitizing compounds; and photocurable compositions comprising the photopolymerizable photosensitizing compound.
