<p>PURPOSE: A double-sided adhesive tape is provided to have excellent adhesion and durability. CONSTITUTION: A double-sided adhesive(100) comprises a substrate(10); and an adhesive layer(20) which includes a polyfunctional acryl group-containing curing agent, and a photoinitiator. The adhesive layer is formed on both sides of the substrate. The gel fraction after curing the adhesive layer is 30-50%. Acryl syrup includes the (meth)acrylic ester monomer. The conversion rate of the acryl syrup is partially polymerized into 5-20%. The weight average molecular weight of the acryl syrup is 800,000-2,000,000 and the viscosity is 100-10,000 cps.</p> |
