[A] An epoxy resin including an aromatic ring and having a functionality of 2 or higher [B] An amine-based hardener or an acid anhydride-based hardener.
摘要:
A method of making a polymer network. The method includes providing a composition including a polythiol having more than one thiol group and a polyepoxide having more than one epoxide group, applying a solution including a photolatent base catalyst to a surface of the composition, and subsequently exposing the composition to light. Upon exposure to light, the photolatent base catalyst photochemically generates a first amine and at least partially cures at least the surface of the composition to form the polymer network.
