PROBLEM TO BE SOLVED: To provide a method for manufacturing a glass base hardly generating chipping on a cut surface of the obtained glass base when cutting a laminate formed by laminating and integrating a plurality of glass sheets with a temporary adhesive.SOLUTION: There is provided a method for manufacturing a glass base used for a touch panel or the like by cutting a laminate formed by laminating and integrating a plurality of glass sheets with a temporary adhesive. One containing a polyfunctional bisphenol A modified epoxy diacrylate, a photoinitiator, a thermal polymerization initiator and foaming agent is used as the temporary adhesive. The polyfunctional bisphenol A modified epoxy diacrylate is one having a molecular weight of around 3000 and the following structural formula. In the formula, R, Rand Rare alkylene groups.SELECTED DRAWING: None |
