Abstract: The present disclosure relates to a color-changing adhesive composition, for example, a color-changing adhesive composition suitable in the preparation of composite materials. The present disclosure also relates to methods of preparing composite materials using color-changing adhesive compositions and to composite-materials comprising such color-changing compositions. In certain embodiments, the present disclosure provides color-changing adhesive compositions having an initial color, where the adhesive composition is capable of changing color to a final color, different from the initial color, once the adhesive compositions contact a curing composition comprising one or more curing agents. In certain embodiments the final color is colorless.
