Abstract: Pet chew articles comprising a consumable body having a shape defined by an exterior surface and comprising a main portion and at least one protrusion extending therefrom with the proviso that the shape of the body is such that no point in the interior of the body is more than about 0.2 inch (? inch) from the portion of the exterior surface nearest to the point. As a result, any pieces of the article that are ingested by a consuming animal are small enough that they will not become lodged within the animal's digestive tract. Also a method for improving the dental health of animals comprising chewing or eating by an animal of such an article.

Abstract: A method for forming an image includes the step of desensitizing a radiation sensitive imaging system comprising a dye and a tetra (hydrocarbyl) borate in a binder by converting the tetra (hydrocarbyl) borate to a compound having fewer than four carbon-to-boron bonds.

Abstract: Acutance agents for use in thermally developable photosensitive compositions are disclosed. These novel compositions absorb scattered light and are rendered colorless at the development temperature of the photothermographic composition.

Abstract: A radiation sensitive element comprising a substrate having coated on at least one side thereof a layer comprising a radiation sensitive tetra(aliphatic) borate salt.

Abstract: The addition of certain classes of aromatic nitrogen containing compounds to photothermographic emulsions stabilizes the background density of the imaged film and/or increases the speed of the emulsion.

Abstract: Acutance agents for use in thermally developable photosensitive compositions are disclosed. These novel compositions absorb scattered light and are rendered colorless at the development temperature of the photothermographic composition.

Abstract: Latent fingerprints having a latency of several weeks are applied to paper substrates using compositions comprising trimeric aliphatic acids of at least 30 carbon atoms which are substantive to paper fibers are substantially non-volatile, and are non-hardening, non-toxic and non-hygroscopic. The latent fingerprints are developed as desired by dusting in the conventional manner with toner particles, suitably, comprising magnetic particles in oleophilic matrix.
