| abstract |
The invention relates to a curable thiol-eno composition comprising either a compound A and a compound B, or a compound B which further comprises a polythiol functionality as defined under (A), where (A) a polythiol, (B ) a compound having a plurality of eno cyclic groups on itself, wherein said compound (B) comprises a carbonyl group directly linked to at least one eno cyclic group and comprises at least one hydrogen donor group, where the distance between the at least one of said enocyclic groups and the at least one of said hydrogen donor groups is at least two skeleton bonds, where compound B does not contain a (meth) acrylate group, and (C) 0-10% by weight of a photoinitiator The invention is further related to the use of such a composition for coating optical fibers, such as stereolithography resin, medical coatings and adhesives. |
