ABSTRACT:
In accordance with the present invention there is provided a system and method for featuring information on a record. The system and method utilize reactant and coreactant compositions which are formulated to produce a color-changing reaction when brought together. The system and method also utilize a record having first and second areas disposed adjacent to each other. The second area is generally treated with the reactant composition. The coreactant composition is formulated to exhibit a first marking color on the first area of the record and to produce a color-changing reaction with the reactant composition on the second area of the record. The color-changing reaction effects a second marking color on the second area. The system and method further utilize a writing implement containing the coreactant composition. The implement is used to deposit the coreactant composition on the first and second areas in the form of symbolic information. The information on the first area exhibits the first marking color, and the information on the second area exhibits the second marking color after the color-changing reaction has taken place. The result of carrying out the system and method of the present invention is that the information is featured on the record by the contrast between the first and second marking colors.
