The present invention improves the long-term storage stability of an organoborane-Lewis base complex. First composite particles of the present invention include particles of an organic polymer (B), and an organoborane-Lewis base complex (A) contained in the particles. Second composite particles of the present invention include particles of an inorganic compound (B'), and an organoborane-Lewis base complex (A) adsorbed on the particles.

Composite particles, kit, material, and method for producing composite particles

An easily removable dental curable composition which prevents the fall or leakage of a temporary prosthetic appliance or a root canal filling material which is easily removed by bonding and adhering it to tooth, shows such high flowability that its operation is easy, has a long working time and excellent X-ray contrast properties and sealability and can be easily removed as required, and a filling kit. The dental curable composition comprises (A) a polymerizable monomer mixture containing a polymerizable monomer having an acid group in the molecule and (B) a polymerization initiator, wherein the component (A) contains (A') a long-chain polymerizable monomer having a structure with a chain length of 17 or more atoms and/or the composition further comprises (D1) a soft resin material.

Easily removable dental curable composition

A dental self-etching primer composition and a dental self-etching primer kit comprising a mixture of (A) a polymerizable monomer, (B) a reducing inorganic compound containing sulfur, (C) a ketone-based solvent and (D) water and having a storage stability of 2 hours or longer at 65&#xb0; C.
