Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
130 words
In a putty-like epoxy adhesive sealant comprising a first band of an uncured epoxy resin composition and a second band, said second band comprising a composition capable of curing of said epoxy resin when said first and second bands are combined to form a substantially uniform mixture, the improvement wherein said uncured epoxy resin composition contains from about 0.02 to about 5%, by weight, of a coloring agent effective to impart latently transient color to said epoxy resin composition which contrasts with the color of said curing composition, said colored epoxy resin composition forming a substantially uniformly colored composition when said epoxy resin composition and said curing composition are combined to form a substantially uniform mixture, said uniformly colored composition becoming essentially colorless with curing of said epoxy resin composition.
Claim 2
Dependent Claim
130 words
In a putty-like epoxy adhesive sealant comprising a first band of an uncured epoxy resin composition and a second band, said second band comprising a composition capable of curing of said epoxy resin when said first and second bands are combined to form a substantially uniform mixture, the improvement wherein said uncured epoxy resin composition contains from about 0.02 to about 5%, by weight, of a coloring agent effective to impart latently transient color to said epoxy resin composition which contrasts with the color of said curing composition, said colored epoxy resin composition forming a substantially uniformly colored composition when said epoxy resin composition and said curing composition are combined to form a substantially uniform mixture, said uniformly colored composition becoming essentially colorless with curing of said epoxy resin composition.
