<P>PROBLEM TO BE SOLVED: To provide a non-solvent type photocurable resin composition capable of forming a protective film which exhibits good and stable adhesion and scratch resistance on a coated surface of an optical disk, etc., and is excellent in transparency. <P>SOLUTION: The non-solvent type photocurable resin composition contains a urethane (meth)acrylate oligomer, a trifunctional (meth)acrylic acid ester monomer, a photopolymerization initiator, and a diluting monomer, wherein a fluorine-based (meth)acrylic acid ester monomer having four more fluorine atoms in its molecule in an amount of 10-40 wt.% and a monofunctional or bifunctional (meth)acrylic acid ester monomer in an amount of 10-30 wt.% are used as the diluting monomer. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
