摘要:
The present invention concerns our discovery that decorative sheets and coverings comprising polyvinyl chloride and having substantially non-migratable through-color images may be prepared using cationic dyestuffs. These coverings may be prepared by providing a variety of polyvinyl chloride-containing substrates with image compositions comprising cationic dyestuffs and a suitable binder, and then treating these materials such that the cationic dyestuffs migrate into the substrate. Through-color images are obtained which are substantially non-migrating, even under severe conditions.

The present invention relates to gasketing materials comprising a rubber binder, a pulverized rice hull filler and a polyester which preferably is crystallizable. The rice hull material acts as a reinforcing filler and, in combination with the rubber and polyester, provides gasketing materials which demonstrate the ability to conform to flange irregularities. As a result, the gaskets demonstrate remarkable sealing capabilities. When they comprise nitrile rubbers, they are also resistant to fuel absorption.

The present invention concerns our discovery that a water-soluble cationic dye and binder composition may be dissolved in a solvent, and, optionally, a magnetic material may be uniformly dispersed within said solvent solution. The resulting solution or mixture is agitated with a hot water solution comprising an ionizable salt whereby there is essentially no partitioning of the cationic dyestuff into the aqueous phase. During the intermixing step, the solvent is driven off, thereby providing a solid mixture of ink which may be pulverized and used in a wide variety of printing processes.
摘要:
A reinforced primary backing for tufted pile fabrics is disclosed. The reinforced primary backing comprises a non-woven fibrous capping layer, a reinforcing material layer, and a woven backing layer, said non-woven fibrous capping layer being positioned adjacent one side of said reinforcing material layer and said woven backing layer being positioned adjacent the other side of said reinforcing material layer, said non-woven fibrous capping layer being needled into and extending downward through said reinforcing material layer and continuing into and through said woven backing layer to the outside surface of said woven backing layer.
