硬化性組成物及び接着剤
Document Type and Number:
Japanese Patent JP6966154
Kind Code:
B2
Abstract:
The present disclosure relates to a curable composition containing 100 parts by mass of a flexible epoxy resin (A), 1 to 150 parts by mass of polymer fine particles (B), and 1 to 200 parts by mass of an epoxy curing agent (C), wherein the polymer fine particles have a core-shell structure and at least two layers of a core layer and a shell layer, the core layer of the polymer fine particles (B) has a glass transition temperature of more than 0 °C as calculated by the following numerical formula (1), a cured product obtained by curing the curable composition has a type A durometer hardness of 5 to 95 at 23 °C as measured by JIS K6253-3, 1 / Tg = £ M i / Tg i wherein M i represents a mass fraction of a monomer unit i selected from butadiene unit and a non-crosslinking monomer unit constituting the core layer of the polymer fine particles (B), and Tg i represents a glass transition temperature (K) of a homopolymer composed of the monomer unit i.
