Claims20
A multi-layer material suitable for use as a covering for an article, the material comprising:
- an elastomeric, polyurethane cellular layer having a density between about 0.2 g/cc to about 0.35 g/cc;
- a nonwoven, cellulose based substrate backing layer, the backing layer being approximately 0.006 inches thick and being a cellulose based non-woven paper saturated with latex, and having between about 12% to about 60% saturation based on dry fiber content;
- and
- a plurality of coatings on the polyurethane cellular layer;
- wherein the material is approximately 0.013 inches in thickness;
- wherein the material has a basis weight of approximately 93 lbs./3,000 ft2;
- and
- wherein the material has a creasability angle of between about 50° and about 130° such that the material is resilient to an extent that a visual mark is not created on a surface of the material after folding, yet not so resilient that the material will pull away from a surface of the article when the material is folded over an edge of the article and adhered to the surface of the article.

A book cover having a covering material, comprising:
- a book cover;
- and
- a cover material adhered to an outward facing surface of the book cover, folded over an edge of the book cover and adhered to an inner facing surface of the book cover, the cover material including:
- an elastomeric, polyurethane cellular layer having a density between about 0.2 g/cc to about 0.35 g/cc;
- a nonwoven, cellulose based substrate backing layer, the backing layer being approximately 0.006 inches thick;
- and
- a plurality of coatings on the polyurethane cellular layer;
- wherein the cover material is approximately 0.013 inches in thickness;
- wherein the cover material has a basis weight of approximately 93 lbs./3,000 ft2;
- and
- wherein the cover material has a creasability angle of between about 20° and about 160° such that the cover material is resilient to an extent that a visual mark is not created on a surface of the material after folding, yet not so resilient that the cover material will pull away from the inner facing surface of the book cover when the cover material is folded over the edge of the book cover and adhered to the inner facing surface of the book cover.

- wherein the covering material is approximately 0.013 inches in thickness;
- wherein the covering material has a basis weight of approximately 93 lbs./3,000 ft2;
- and
- wherein the covering material has a creasability angle of between about 20° and about 160°.
