Time validation indicator |
| abstract |
A time validation indicator is disclosed comprising at least a receiving layer and an activating layer. The receiving layer comprises at least one or more masking colorants and one or more deactivators that cause and maintain the one or more masking colorants in an initial colored state. The activating layer comprises at least one or more migratory activators that migrate into the receiving layer upon at least a portion of the receiving layer being placed in contact with at least a portion of the activating layer to initiate a predetermined time period. The migration of the one or more migratory activators into the receiving layer causes at least a portion of the one or more masking colorants to advance to a final colorless state resulting in a visual color change of the receiving layer that indicates the predetermined time period has elapsed. Also disclosed are methods for creating and using the inventive time validation indicator. |
