Patent ID: 8703839

Claim:
An activation energy ray-curable resin composition comprising 70 to 95 parts by mass of a multifunctional monomer (A) which has a surface free energy of 37 mJ/m 2 or more when cured and 5 to 30 parts by mass of a fluorine (meth)acrylate (B) which is compatible with the multifunctional monomer (A) (a total content of all monomers in the composition shall be 100 parts by mass), and further comprising 20 parts by mass or less of a fluorine (meth)acrylate (C) which is incompatible with the multifunctional monomer (A), wherein the multifunctional monomer (A) has three or more radical polymerizable functional groups in the molecule, and a value of the molecular weight divided by the number of the radical polymerizable functional group (Molecular weight/Number of radical polymerizable functional group) is in 110 to 200, and the fluorine (meth)acrylate (B) has one or more radical polymerizable functional groups in a molecule, and wherein the following equation is satisfied: [ b ×content of ( B )+ c ×content of ( C )]/[content of ( B )+content of ( C )]≦51.5% in which the fluorine content b is a value of a total mass of fluorine atom contained in the fluorine (meth)acrylate (B) divided by the molecular weight of fluorine (meth)acrylate (B), and the fluorine content c is a value of a total mass of fluorine atom contained in fluorine (meth)acrylate (C) divided by the molecular weight of fluorine (meth)acrylate (C).
