PROBLEM TO BE SOLVED: To provide a photocurable resin composition excellent all in transparency, heat resistance, flexibility, follow up ability to unevenness and releasability without generating bleedout.SOLUTION: There is provided the photocurable resin composition which contains following components (A) to (D), the amount of the component (A) being set in a range of 30 to 70 pts.wt., the amount of the component (B) being set in a range of 10 to 40 pts.wt., the amount of the component (C) being set in a range of 10 to 30 pts.wt. and the amount of the component (D) being set to be 0.5 to 2.0 pts.wt based on 100 pts.wt. of the total amount of the components (A), (B) and (C). (A) a solid epoxy resin having an epoxy equivalent of 7000 to 13000 g/eq. (B) a solid epoxy resin having an epoxy equivalent of 400 to 1000 g/eq. (C) a liquid epoxy resin having a viscosity at 25°C of 12 to 25 Pa s. (D) an optical acid generator. |
