Abstract
Abstract A sheet material for mounting on a substrate such as a wall, and displaying an article such as a greeting card, comprising a film backing, a first repositionable adhesive coating on one surface, and a second repositionable coating on the other surface. The sheet material permits the article to be adhered to, repositioned on, and removed from the sheet material without removing the sheet material from the substrate to which it has been adhered.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
218 words
A sheet material for mounting on a substrate and displaying an article, comprising a substantially smooth, flexible film backing, a coating of a first repositionable adhesive on a first major surface of said backing for removably adhering said sheet material to said substrate, and a coating of a second repositionable adhesive on a second major surface of said backing for, adhering said article to said sheet material, said first repositionable adhesive coating providing a higher level of adhesion per unit area of said sheet material than said second repositionable adhesive coating by virtue of said first repositionable adhesive being more aggressive an adhesive than said second repositionable adhesion such that the adhesion level provided by said first repositionable adhesive coating is at least about 50 gram/cm width higher than that provided by said second repositionable adhesive coating when tested according to Test Method A, and the adhesion level provided by said second repositionable adhesive coating is about 30 to about 55 gram/cm width when tested according to Test Method A, such that when said first repositionable adhesive coating is contacted with said substrate to which said sheet material is being adhered, said article which is being adhered to said second repositionable adhesive coating can be repositioned thereon and removed therefrom without removing said sheet material from said substrate.
Claim 2
Dependent Claim
218 words
A sheet material for mounting on a substrate and displaying an article, comprising a substantially smooth, flexible film backing, a coating of a first repositionable adhesive on a first major surface of said backing for removably adhering said sheet material to said substrate, and a coating of a second repositionable adhesive on a second major surface of said backing for, adhering said article to said sheet material, said first repositionable adhesive coating providing a higher level of adhesion per unit area of said sheet material than said second repositionable adhesive coating by virtue of said first repositionable adhesive being more aggressive an adhesive than said second repositionable adhesion such that the adhesion level provided by said first repositionable adhesive coating is at least about 50 gram/cm width higher than that provided by said second repositionable adhesive coating when tested according to Test Method A, and the adhesion level provided by said second repositionable adhesive coating is about 30 to about 55 gram/cm width when tested according to Test Method A, such that when said first repositionable adhesive coating is contacted with said substrate to which said sheet material is being adhered, said article which is being adhered to said second repositionable adhesive coating can be repositioned thereon and removed therefrom without removing said sheet material from said substrate.

A sheet material according to claim 1, wherein said second repositionable adhesive coating is substantially transparent.
Claim 6
Dependent Claim
20 words
A sheet material according to claim 4, wherein said second major surface of said backing has a decorative design thereon.
Claim 7
Dependent Claim
17 words
A sheet material according to claim 1, further comprising a release liner adhered to said second surface.
Claim 8
Dependent Claim

Claim 9
Dependent Claim
16 words
A sheet material according to claim 7, having a width of about 2 to 5 inches.
Claim 10
Dependent Claim
52 words
A sheet material according to claim 7, wherein when said sheet material is unwound, the level of adhesion between said release liner and said first repositionable adhesive coating and said release liner and said second repositionable adhesive coating is such that said release liner remains adhered to said second repositionable adhesive coating.
Claim 11
Dependent Claim
43 words
A sheet material according to claim 6, wherein when said sheet material is adhered to a substrate by said first repositionable adhesive coating, said release liner can be removed from said second repositionable adhesive coating without removing said sheet material from said substrate.
Claim 12
Dependent Claim
16 words
