Packaging form of radical polymerizable composition

[Abstract] The present invention is to provide a packaging bag using a heat sealable synthetic resin sheet to contain a radically polymerizable composition and air. In a preferred embodiment, the packaging bag has at least one layer of a metal layer or the like for blocking at least one of a solvent, a gas, a visible light, and an ultraviolet ray, and is, for example, a synthetic resin from inside to outside. Sheet (1)/adhesive layer (2)/synthetic resin sheet (3)/metal layer (4)/synthetic resin sheet (5) is made of a 5-layer laminate structure sheet. The amount of air in the packaging bag is preferably 1% to 50% of the capacity of the radically polymerizable composition, and the sheet for the packaging bag preferably has a total thickness of 50 to 300 μm and a metal layer thickness of 5 μm or more. This package form ensures the stability over time of the radically polymerizable composition during storage and ensures safety at the time of transportation. Therefore, it is preferable as a packaging form of a radical polymerizable composition such as a protective layer ink.

[Summary Item] 1. A packaged form of a radically polymerizable composition, characterized in that a radical polymerizable composition and air are accommodated in a packaging bag using a heat sealable synthetic resin sheet.
