Abstract: An epoxy adhesive sealant composition comprised of an uncured epoxy resin composition and a composition capable of curing the epoxy resin composition, one of said compositions containing a coloring agent effective to impart latently transient color to said composition unlike the color of the non-colored composition. Substantially equal amounts of each of said compositions are combined to form a substantially uniformly colored composition which becomes essentially colorless with curing of the epoxy resin composition.
