Abstract: The adhesive composition for soft tissues, the adhesive composition for wound dressing or the wound dressing agent composition of the present invention is an adhesive composition for soft tissues, an adhesive composition for wound dressing or a wound dressing agent composition, comprising a monomer (A), a polymer (B) and a polymerization initiator composition (C) containing an organoboron compound, and is characterized by having a viscosity of 0.4 to 75,000 cp within 30 seconds after mixing of the components (A), (B) and (C). The composition of the present invention not only has low toxicity, low harmfulness and high adhesive strength but also is excellent in workability during application and is capable of forming films of excellent properties.

Abstract: The composition for hard tissue repair of the present invention is characterized by comprising 5 to 98.95 parts by weight of a monomer (A), 1 to 75 parts by weight of a (meth)acrylate polymer (B) and 0.05 to 20 parts by weight of a polymerization initiator composition (C) containing an organoboron compound (c1), with the proviso that the total amount of the components (A), (B) and (C) is 100 parts by weight. The composition undergoes small-scale heat generation during curing and can ensure a sufficient working time.
