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.

Abstract: A layered envirochromic material is described herein that contains at least one substrate or surface material; at least one base layer coupled to the at least one substrate or surface material; and at least one envirochromic layer coupled to the at least one base layer. Methods of producing the layered envirochromic materials include providing a surface or substrate; applying at least one base layer component on to the surface; curing the at least one base layer component to form a base layer; applying at least one envirochromic layer component on to the surface; and curing the at least one envirochromic layer component to form the envirochromic layer. Additional methods include providing a surface or substrate; applying at least one base layer component on to the surface; applying at least one envirochromic layer component on to the at least one base layer component; and curing the at least one base layer component and at least one envirochromic layer component to form the layered material.

Abstract: Paper compositions are provided that include an amine group-containing cationic polymeric material and a binder material. The paper compositions are particularly useful as receiver materials for images formed by electrophotographic imaging methods utilizing liquid developers. Also described are imaging methods that utilize the paper compositions as receiver materials and methods for manufacturing the paper.
