8results about "Sulfur dyes" patented technology

An absorbent article having a topsheet, a backsheet, an absorbent core disposed at least partially between the topsheet and the backsheet, and a wetness indicating composition is provided. The wetness indicating composition includes a colorant and a colorant fastener. The colorant has a first color state, wherein the first color state is associated with a first state of the wetness indicating composition. The colorant has a second, different color state, wherein the second color state is associated with a second state of the wetness indicating composition. The wetness indicating composition is disposed on the absorbent article in a plurality of discrete graphics, wherein each of the plurality of discrete graphics has an area of between about 0.02 cm2 and about 25 cm2.
