The invention generally relates to novel poly-substituted cis stilbenes, their synthesis, their purification, and their use in thermoset resins. These novel cis stilbenes give rise to thermoset resins with greatly improved processing characteristics such as lower melting temperature and lower viscosity; resulting in polymers and composites having greatly improved thermal stability.

A surface marker resin formulation is provided that includes a linear aromatic polyester or a co-polymer thereof present in an amount of 10 to 45 total weight percent. The resin is dissolved or dispersed in a solvent. A colorant package is also dissolved or dispersed in the solvent. Upon drying of the solvent a mark is provided on a surface that can alert a user as to relative movement between articles defining the surface. A process of marking a surface includes two articles being brought into a pre-selected alignment to define a surface. A continuous bead is applied to the surface. The solvent evaporates to a state of dry-to-touch in a time of between 1 and 30 minutes to mark the surface.
