The present invention relates to a pressure-sensitive adhesive composition, a protective film for polarizers, which includes a cured product of the pressure-sensitive adhesive composition, a polarizer, and a liquid crystal display (LCD). In the present invention, a pressure-sensitive adhesive showing excellent endurance reliability in high-temperature and/or high-humidity conditions and having superior physical properties such as cuttability, re-peeling property, and workability can be provided. In particular, it is possible to provide the pressure-sensitive adhesive composition which can prevent light leakage that may occur in an LCD, even when being applied to a film having a low stress optical coefficient.

An aluminum-chelate-based latent curing agent is capable of showing excellent solvent resistance and excellent storage stability at room temperature without impairing low temperature rapid curability of resin composition, when preparing one-pack type thermosetting epoxy resin composition by blending aluminum-chelate-based latent curing agent holding aluminum-chelating agent on porous resin particles obtained by subjecting polyfunctional isocyanate compound to interfacial polymerization into alicyclic epoxy resin showing extremely high cationic polymerizability. Aluminum-chelate-based latent curing agent for curing thermosetting epoxy resin is configured such that aluminum-chelating agent is held on porous resin obtained by subjecting polyfunctional isocyanate compound to interfacial polymerization, and that surface activity inhibition treatment is performed by epoxy-alkoxy-silane coupling agent.
