ENERGY BEAM CURABLE ADHESIVE COMPOSITION FOR FORMING PERFORATED STRUCTURE FOR ELECTROPHORETIC DISPLAY, PRESSURE SENSITIVE ADHESIVE SHEET FOR FORMING PERFORATED STRUCTURE, AND PERFORATED STRUCTURE AND ELECTROPHORETIC DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide an energy beam curable conductive adhesive composition forming a perforated structure for electrophoretic display, and a pressure sensitive adhesive sheet.SOLUTION: The energy beam curable adhesive composition forming the perforated structure for electrophoretic display forms a perforated structure which is a structure including a hollow part for containing electrophoretic liquid of an electrophoretic display performing display by applying a voltage to the electrophoretic liquid including dispersed charged particles to move the charged particles. The energy beam curable adhesive composition contains energy beam curable insulation resin and conductive fine particles dispersed in the energy beam curable insulation resin. An energy beam curable conductive adhesive composition has a rupture elongation of 500% or more before energy beam curing, and a stress relaxation rate of 70% or more and 95% or less. The conductive fine particle is composed of metal oxide and has a particle size of 1000 nm or less.
