PURPOSE: To provide a rapid-curing composite hot-melt adhesive, having excellent melt stability, composed of a polyester curable in air, and additives such as a polymerization initiator, a polymerization accelerator or a photo-sensitizer, wherein said polyester and said additives are combined together to form a bonded-type, sheath- and-core-type or sea-and-island type composite.
CONSTITUTION: A composite adhesive composed of a polyester curable in air, or a composition containing the polyester as a main component, and (B) additives such as a polymerization initiator, a polymerization accelerator or a photo-sensitizer, or a composition containing the additives. The (A) component and the (B) component are combined together to form a bonded type, a sheath-and-core type or a sea- and-island type composite. The air-curable polyester is polyester composition derived from an air-curing component, a polybasic carboxylic acid and a polyhydric alcohol, and the air-curing component is a monomer having a straight-chain unsaturated aliphatic group, a saturated cycloaliphatic group, etc., pref. a compound having tricyclodecene ring.
