Title:
ADHESIVE SHEET
Document Type and Number:
Japanese Patent JP2017222805
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a composition for producing an adhesive sheet which can reduce surface roughness of an adhesive sheet to be produced and can prevent air bubbles from remaining in a laminate produced by sticking two substrates through the adhesive sheet.SOLUTION: A composition for producing an adhesive sheet 12 contains EVA and a crosslinking agent, where viscosity (V) at 60°C of EVA and viscosity (V) at 90°C thereof satisfy expression (I): (V-V)/V×100≤93(%), the viscosity (V) at 90°C of the EVA and viscosity (V) at 110°C thereof satisfy expression (II): (V-V)/V×100≥30(%), and viscosity at 100°C of the EVA is 8.4×10to 1.5×10Pa s.SELECTED DRAWING: Figure 1
