Abstract
A composition containing an epoxide compound with two or more epoxide groups, a thiol ester with two or more ester groups and two or more thiol groups and/or a thiol ether with two or more thiol groups, and 0.005-2 wt. %, based on the total weight of the composition, of a tertiary amine which has a 5- or 6-membered aliphatic nitrogen heterocycle, said composition containing less than 1 wt. % of a primary amine. The composition can be used as, an embedding medium for microscopy and as an adhesive and to an optical element which comprises the composition.
