Abstract:
[Problem] To contribute to SDGs by making it possible to provide a (semi-)transparent clear file with sufficient durability[Means for Solving] A (semi-)transparent clear file of the present invention comprises (semi-)transparent covering paper P in which at least one surface of raw material paper R is covered with a cured product of a resin composition L. The resin composition L contains an energy ray polymerizable (meth)acrylic monomer and/or oligomer having a viscosity at 25° C. of 100 mPa·s or less, and glass transition temperature Tg of the cured product of 50° C. or higher. A basis weight of the paper is 65 g/m2 or more and 100 g/cm2 or less. The paper has a thickness of 80 μm or more and 100 μm or less. A proportion of the paper to 100 pts. mass of the covering paper P is 50 pts. mass or more, and a proportion of the cured product is less than 50 pts. mass. The monomer and/or the oligomer are/is preferably alkali-soluble, and also preferably contain/contains an inert resin. The raw material paper R is preferably uncoated paper.
