First claim
Opening claim text (preview).
The invention claimed is: 1. A photo-curable resin composition for an adhesive film, the photo-curable resin composition comprising a (meth)acrylic acid ester-based photo-curable resin, which is end-capped and cross-linked with a multifunctional molecular weight regulator, wherein the (meth)acrylic acid ester-based photo-curable resin is obtained from a mixture comprising a (meth)acrylic acid ester-based monomer, a cross-linkable monomer and the multifunctional molecular weight regulator, and the content of the multifunctional molecular weight regulator is 0.001 to 1.0 parts based on 100 parts by weight of the (meth)acrylic acid ester-based monomer, wherein the cross-linkable monomer comprises at least one selected from a hydroxyl group-containing monomer, a carboxyl group-containing monomer and a nitrogen-containing monomer, and wherein the (meth)acrylic acid ester-based photo-curable resin has a weight average molecular weight of 1,700,000 to 15,000,000. 2. The photo-curable resin composition of claim 1 , wherein the multifunctional molecular weight regulator is multifuntional as having at least two functional groups. 3. The photo-curable resin composition of claim 1 , wherein the multifunctional molecular weight regulator is a tri-functional to hexa-functional thiol-containing compound. 4. The photo-curable resin composition of claim 1 , wherein the multifunctional molecular weight regulator comprises at least one selected from the group consisting of tris-[(3-mercaptopropionyloxy)-ethyl]isocyanurate, trimethylolpropane tris-3-mercaptopropionate, pentaerythritol tetrakis-3-mercaptopropionate, dipentaerythritol hexa-3-mercaptopropionate, and pentaerythritol tetrakis(3-mercaptobutyrate). 5. The photo-curable resin composition of claim 1 , wherein the (meth)acrylic acid ester-based monomers are a cured material of an acrylic photo-curable resin composition or an epoxy acrylate-based photo-curable resin composition comprising at least one selected from the group consisting of methyl (meth)acrylate, ethyl (meth)acrylate, n-propyl (meth)acrylate, isopropyl (meth)acrylate, n-butyl (meth)acrylate, t-butyl (meth)acrylate, sec-butyl (meth)acrylate, pentyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, 2-ethyl-butyl (meth)acrylate, n-octyl (meth)acrylate, isooctyl (meth)acrylate, isobornyl (meth)acrylate, and isononyl (meth)acrylate. 6. The photo-curable resin composition of claim 1 , wherein the cross-linkable monomer comprises at least one selected from the group consisting of 2-hydroxyethyl (meth)acrylate, 2-hydroxypropyl (meth)acrylate, 4-hydroxybutyl (meth)acrylate, 6-hydroxyhexyl (meth)acrylate, 8-hydroxyoctyl (meth)acrylate, 2-hydroxyethyleneglycol (meth)acrylate, 2-hydroxypropyleneglycol (meth)acrylate, (meth)acrylic acid, 2-(meth)acryloyloxy acetic acid, 3-(meth)acryloyloxy propyl acid, 4-(meth)acryloyloxy butyl acid, acrylic acid dimer, itaconic acid, maleic acid, 2-isocyanatoethyl (meth)acrylate, 3-isocyanatopropyl (meth)acrylate, 4-isocyanatobutyl (meth)acrylate, (meth)acrylamide, N-vinyl pyrrolidone, and N-vinyl caprolactam. 7. The photo-curable resin composition of claim 1 , further comprising a photo-initiator. 8. The photo-curable resin composition of claim 7 , wherein the photo-initiator comprises at least one selected from the group consisting of a phosphorus-benzo initiator, a hydroxy ketone-based initiator, an aminoketone-based initiator, and a caprolactam-based initiator. 9. An adhesive film comprising a photo-cured material of the photo-curable resin composition for the adhesive film according to claim 1 .
