Abstract:
1. A sealant composition for a plastic liquid crystal display cell, comprising: a two-component epoxy resin composition comprising a base resin liquid containing the following (1) and (3) to (6) and a curing agent liquid containing the following (2A) or a mixture of the following (2A) and (3), wherein the two-component epoxy resin composition is obtained from a two-component mixture of the base resin liquid and the curing agent liquid and contains the following (1) to (6): (1) from 15 to 84% by weight of a liquid epoxy resin having from 1.7 to 6 in weight average of epoxy groups in one molecule and an ionic conductivity of an aqueous solution obtained by extraction separation by contact mixing with 10 times by weight of pure water at from 40 to 80° C. of 2 mS/m or less, (2A) from 10 to 50% by weight of a curing agent containing one or a mixture of two or more selected from (2A-1) a tetrafunctional mercapto compounds or (2A-2) modified polymercapto derivatives, having an ionic conductivity of an aqueous solution obtained by extraction separation by contact mixing with 10 times by weight of pure water at from 40 to 80° C. of 0.6 mS/m or less, (3) from 0.01 to 15% by weight of a curing accelerator, (4) from 5 to 50% by weight of an inorganic filler, (5) from 0.1 to 5% by weight of a silane coupling agent, and (6) from 1 to 25% by weight of rubbery polymer fine particles having a softening temperature of 0° C. or less and an average particle diameter of primary particles of from 0.01 to 5 μm.
