Abstract
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.
