PHOTOCURABLE RESIN COMPOSITION CAPABLE OF PROVIDING AN EXCELLENT IMITATION MOLD WITH HIGH YOUNG'S MODULUS AND ELASTICITY, FLEXIBILITY, AND GAS PERMEABILITY, AND A MANUFACTURING METHOD OF THE IMITATION MOLD

摘要

PURPOSE: A photocurable resin composition is provided to make an additional releasing agent treatment unnecessary, and to satisfy low viscosity, low surface tension, high Young's modulus, wide range elasticity, a low shrinkage ratio, a low swelling rate, high transparency, and high gas permeability.;CONSTITUTION: A photocurable resin composition comprises a photoreactive polymer that polydimethylsiloxane is coupled to silsesquioxane which has one or more polymerizable functional groups. The weight average molecular weight of the polydimethylsiloxane is 1,000-4,000. A manufacturing method of the imitation mold comprises a step of spreading the photocurable resin composition on a first substrate; and a step of arranging a second substrate on the first substrate, and curing the same.;COPYRIGHT KIPO 2013
