Abstract
A curing agent composition is capable of curing a base resin containing a 2-methylene-1,3-dicarbonyl compound. The curing agent composition contains a specific 2-methylene-1,3-dicarbonyl compound and an initiator. A two-part mixing adhesive contains the curing agent composition and a base resin containing another specific 2-methylene-1,3-dicarbonyl compound.
Claims14
A two-part mixing adhesive kit, wherein:
- (i) a first part of the two-part mixing adhesive kit includes a curing agent composition comprising:
- (a) an initiator comprising at least one basic substance, and
- (b1) at least one first 2-methylene-1,3-dicarbonyl compound having a molecular weight of 180 or higher and 10,000 or lower, the first 2-methylene-1,3-dicarbonyl compound comprising at least one structural unit represented by formula (I), and
- (ii) a second part of the two-part mixing adhesive kit includes a base resin comprising (b2) at least one second 2-methylene-1,3-dicarbonyl compound, the second 2-methylene-1,3-dicarbonyl compound comprising at least one structural unit represented by formula (I), and
- wherein formula (I) is
