Abstract
Abstract The present invention relates to structures exhibiting unique appearances resulting from the presence of crinkled chip materials. A reflective and/or nacreous platelet or flake material is intermixed with a plasticizer and a general purpose resin, and the mixture is formed into a reflective sheet. The reflective sheet is pulverized to provide a chip material which is then used alone or in combination with other chips to form a mottle comprising a vinyl chloride resin and a plasticizer. Upon consolidating the mottle into a decorative surface, the nacreous and/or reflective chips are found to surprisingly exhibit an enhanced crinkled appearance, thereby exhibiting unique aesthetic properties.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
128 words
A compounded mottle derived from (a) a chip material having a substantially smooth reflective surface and exhibiting pearlescent or metallic properties, said chip material being large enough to be retained on a 25-mesh screen (U.S. Standard) but being not greater than about 0.25 inch in diameter and being derived from a particulate material having reflective or pearlescent properties, a millable general purpose resin, and a plasticizer; (b) a particulate vinyl resin, and (c) a plasticizer, said particulate resin and proportions of (a), (b) and (c) being selected such that said mottle is amenable to processing at 300° F. to provide a transparent vinyl matrix wherein said chips exhibit an enhanced crinkled appearance relative to the appearance of the uncompounded chips, said mottle being in a loose, unconsolidated form.
Claim 2
Dependent Claim
128 words
A compounded mottle derived from (a) a chip material having a substantially smooth reflective surface and exhibiting pearlescent or metallic properties, said chip material being large enough to be retained on a 25-mesh screen (U.S. Standard) but being not greater than about 0.25 inch in diameter and being derived from a particulate material having reflective or pearlescent properties, a millable general purpose resin, and a plasticizer; (b) a particulate vinyl resin, and (c) a plasticizer, said particulate resin and proportions of (a), (b) and (c) being selected such that said mottle is amenable to processing at 300° F. to provide a transparent vinyl matrix wherein said chips exhibit an enhanced crinkled appearance relative to the appearance of the uncompounded chips, said mottle being in a loose, unconsolidated form.
Claim 3
Dependent Claim
47 words
The invention as set forth in claim 1 hereof wherein said chip material is derived from 100 parts by weight of general purpose resin, from about 20 to about 45 parts of plasticizer and from about 1 to about 5 parts of reflective or pearlescent particulate material.
Claim 4
Dependent Claim
51 words
The invention as set forth in claim 1 hereof wherein said mottle comprises from about 7 to about 30 parts of resin, from about 91 to about 60 parts of chips, and from about 2 to about 10 parts of plasticizer, said components comprising a total of 100 parts by weight.
Claim 5
Dependent Claim
33 words
The invention as set forth in claim 3 hereof wherein said particulate materials having reflective or pearlescent properties are selected from the group consisting of coated mica pearlescent pigments and particulate metallic materials.
Claim 6
Dependent Claim
