CROSS-LINKING OF POLYACRYLATE WITH ELECTRON BEAM

摘要

PROBLEM TO BE SOLVED: To obtain an acrylic pressure-sensitive adhesive(PSA) composition having good processability of a starting material and an intermediate for a hot-melt technique and further, having a combination of a good bonding strength with a good tack and an ultimate shear strength. SOLUTION: This method of cross-linking a polyacrylate composition is characterized in that a polymer is cured only in a certain structure by selective irradiation of a pressure-sensitive adhesive composition with electron beams and a structured pressure-sensitive adhesive composition can resultantly be produced.
