A transfer method includes the steps of placing a donor substrate including a support base and a transfer layer provided on the support base onto a receptor substrate such that the transfer layer faces the receptor substrate, evacuating a space between the receptor substrate and the donor substrate that are placed one on the other, and transferring the transfer layer onto the receptor substrate by applying a radiant ray onto the donor substrate in an evacuated atmosphere.

Improvements in permitting brighter colorations within polypropylene fibers and/or yarns while simultaneously providing more efficient production methods of manufacturing of such colored fibers as well are provided. Generally, such fibers and/or yarns have been colored with pigments, which exhibit dulled results, or dyes, which exhibit high degrees of extraction and low levels of lightfastness. Such dull appearances, high extraction levels, and less than stellar lightfastness properties negatively impact the provision of such desirable colored polypropylene fibers and/or yarns which, in turn, prevents the widespread utilization of such fibers and yarns in various end-use applications. Thus, it has surprisingly been determined that brighter colorations, excellent extraction, and more-than-acceptable lightfastness characteristics can be provided, preferably, through manufacture with certain polymeric colorants that include poly(oxyalkylene) groups thereon. Fabric articles comprising such novel fibers and/or yarns are also encompassed within this invention.

The present invention relates to a method of producing activated color regions in a web substrate where activated color regions are formed coinciding with deformed regions.

An elastomeric article that contains a chromogen that undergoes a detectable change in color in the presence of one or more microbes is provided. For example, in one embodiment, the chromogen is a solvatochromic dye (e.g., Reichardt's dye) that undergoes a color change in the presence of bacteria or other microbes. More specifically, such dyes may respond to differences in polarity between microbe components (e.g., cell membrane, cytoplasm, etc.) and the environment outside the cell. Alternatively, other mechanisms may be wholly or partially responsible for the interaction between the dye and the microbe, such as acid-base reactions, redox reactions, and so forth.
