Abstract
A protective coat layer-forming composition is used for forming a protective coat layer of a protective coat layer-laminated film including a base film made of a cyclic olefin resin and the protective coat layer formed on at least one side of the base film. The protective coat layer-forming composition includes a component (A) of a multifunctional acrylate monomer, a component (C) of an isocyanuric acid derivative having two or more (meth)acryloxy groups, a component (D) of a caprolactone oligomer derivative having three or more (meth)acryloxy groups, and a component (E) of a photopolymerization initiator.
Claims7
A photocurable composition comprising the following components (A), (B), (C), (D), and (E):
- Component (A), a multifunctional acrylate monomer comprising at least one selected from the group consisting of bisphenol F EO-modified di(meth)acrylate, bisphenol A EO-modified di(meth)acrylate, trimethylolpropane tri(meth)acrylate, dicyclopentenyl (meth)acrylate, dicyclopentenyloxyethyl (meth)acrylate, neopentyl glycol di(meth)acrylate, pentaerythritol tri(meth)acrylate, and dipentaerythritol hexa(meth)acrylate, wherein a content of the component (A) is 5 to 30% by mass;
- Component (B), a multifunctional acrylate oligomer having a molecular weight of from 500 to 10,000 selected from the group consisting of a urethane(meth)acrylate having at least six (meth)acryloyl groups, a difunctional urethane acrylate, a multifunctional polyester acrylate, a phenylglycidylether acrylate hexamethylene diisocyanate urethane, and a phenylglycidylether acrylate toluene diisocyanate urethane, wherein a content of the component (B) is 10 to 30% by mass, and a total content of the components (A) and (B) is 40% by mass or lower;
- Component (C), an isocyanuric acid derivative having two or more (meth)acryloxy groups, wherein a content of the component (C) is 5 to 40% by mass;
- Component (D), a caprolactone oligomer derivative having three or more (meth)acryloxy groups, wherein a content of the component (D) is 37 to 79% by mass, and the component (B) is not the same as the component (D);
- and
- Component (E), a photopolymerization initiator, wherein a content of the component (E) is 1 to 10% by mass.
