Abstract

Adhesives and primer compositions that include water, a polymer and a pH indicator. The adhesives and primers have a visually-detectable color when wet, and preferably dry to a clear or transparent film, while having good flow and spreadability. The adhesives and primers provide a visual indication of wetness by including a pH indicator such that when the composition is wet, the pH indicator is colored such that the color and the intensity of the color provides a visual indication of wetness; sufficiency of thickness; and uniformity of application of the adhesive or primer.

Description

[0001] This invention generally relates to adhesives and primers used in applying wallpaper to walls. More particularly, the invention relates to wallpaper adhesives and primers that are colored when wet and dry clear or transparent for ease in application to ensure that an entire wall, or an entire back side of the wallpaper is completely covered with the adhesive or primer, that the adhesive or primer is applied evenly to the wall or wallpaper, and to easily determine, by color difference, if a portion of the applied adhesive or primer is too dry to function so that additional adhesive or primer can be applied at selected locations.BACKGROUND OF THE INVENTION AND PRIOR ART[0002] Wallpaper is used to decorate the interior walls of homes, hotels, offices, hospitals and other structures where people live, work and meet. A typical wall is made from a plaster or, in the case of drywall, a gypsum core covered on its major surfaces with paper.[0003] The wallpaper is held to a wall by an ...
