Document Type and Number:
WIPO Patent Application WO/2018/124371
Kind Code:
A1
Abstract:
The present invention relates to an ultraviolet curable adhesive tape and a manufacturing method therefor. The present invention relates to an adhesive tape comprising an ultraviolet curable adhesive composition having a low cure shrinkage, the adhesive composition comprising: a resin syrup prepared by partially polymerizing monomers comprising 70-99 parts by weight of a (meth)acrylate-based monomer having a C1-20 alkyl group, 1-30 parts by weight of a polar monomer capable of copolymerizing with the monomer, and 0.01-10 parts by weight of a photoinitiator; a photoinitiator; a cross-linking agent; and a xylene-based resin. The present invention can prepare an adhesive resin having a low cure shrinkage by adding a xylene-based resin to an adhesive resin composition, and the adhesive tape comprising the adhesive resin composition, of the present invention, allows warpage caused by a shrinkage phenomenon to be greatly reduced, and thus there are advantages enabling damage to an adhesive surface to be minimized and enabling the problem of adhesive strength deterioration caused by a shrinkage phenomenon to be overcome.
