[EN] CURABLE DENTAL COMPOSITIONS AND USES THEREOF [FR] COMPOSITIONS DENTAIRES DURCISSABLES ET LEURS UTILISATIONS
摘要:
A curable dental composition includes a compound having structural formula (A) where X is an amine-, oxygen-, or sulfur -containing linkage; Y is an amine-, oxygen-, or sulfur -containing linkage; n is 1 - 15; m is 1 - 5; p is 1-5, with the proviso that when p is greater than 1, m is 1; each R1is, independently, an alkyl or aryl group having 2 to 20 carbon atoms that is linear, branched, cyclic, or some combination thereof, and optionally includes one or more heteroatoms or unsaturated bonds; and each R2is, independently, a hydrogen atom or CH3The composition also includes filler. The filler is present in an amount of at least 25 wt.-%, based on the total weight of the curable dental composition.
According to the present invention, a lens adhesive including a compound represented by General Formula 1 is provided.

In the formula, Ar is an aromatic ring group represented by General Formula 2-2 and the like.
In the formula, Z

and the like (where Rz is a substituent, and two Rz's may form a ring); L
1
and L
2
each represent a single bond, —O—, —OC(═O)—, —OC(═O)O—, —OC(═O)NH—, and the like; Sp
1
and Sp
2
each represent a single bond or a linking group such as a linear alkylene group; Pol
1
and Pol
2
each represent a hydrogen atom or a polymerizable group; and a compound represented by General Formula 1 has at least one polymerizable group. Using the lens adhesive, it is possible to provide a cemented lens that is unlikely to deteriorate due to light, and an imaging module having high durability.
