Claim:
1. An anti-microbial paper towel with a chromatic transfer indicator comprising: a) a cellulosic web; b) a transferable lotion composition comprising an emollient and an anti-microbial agent, the lotion composition being immobilized on the cellulosic web in a semi-solid or solid form and selected and applied in amounts such that it imparts a water absorption rate delay of at least about 25% to the cellulosic web, wherein the transferable lotion composition is selected from lotion compositions which are transferable upon contact with water or lotion compositions which are transferable upon application of heat; c) a pH-sensitive transfer indicator disposed on the web at a plurality of discrete indicator locations; and d) a water soluble indicator triggering agent disposed on the web at a plurality of discrete triggering agent locations which are apart from the pH-sensitive transfer indicator locations, wherein the water soluble indicator triggering agent is a non-toxic organic acid, inorganic acid, or a buffer solution; wherein the pH-sensitive transfer indicator and indicator triggering agent are selected and applied to the web such that the pH-sensitive transfer indicator undergoes a visually perceivable color change upon contact of the towel with water after a characteristic time delay of at least about 5 seconds, wherein the initiation of said color change is determined by a wicking time of the indicator triggering agent.
