Abstract
Abstract A sheet material having a decorative surface and a working surface, for application to a support surface is disclosed, the working surface of which is provided with a continuous coating of tacky, pressure-sensitive, adhesive, which adhesive is provided with a coating of a discontinuous layer of resilient, non-adhesive particles. The coating of particles have the ability to be deformed under a load and thus, upon application to a support surface, deform, under pressure, to such an extent as to bring the adhesive and the surface into fuller contact.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
59 words
A sheet material having a decorative surface and a working surface, the working surface being provided with a continuous coating of a tacky, pressure-sensitive, adhesive, the improvement comprising providing on the adhesive coating a discontinuous layer of resilient, non-adhesive, solid particles of a material selected from a foamed organic polymeric material, a natural or synthetic rubber or blends thereof.
Claim 2
Dependent Claim
59 words
A sheet material having a decorative surface and a working surface, the working surface being provided with a continuous coating of a tacky, pressure-sensitive, adhesive, the improvement comprising providing on the adhesive coating a discontinuous layer of resilient, non-adhesive, solid particles of a material selected from a foamed organic polymeric material, a natural or synthetic rubber or blends thereof.
Claim 3
Dependent Claim
26 words
A sheet material as claimed in claim 1 in which between 5% and 20% of the available adhesive surface is covered by the non-adhesive resilient particles.
Claim 4
Dependent Claim
22 words
A sheet material as claimed in claim 1 in which the discontinuous layer of resilient particles is covered with a release paper.
Claim 5
Dependent Claim
43 words
A sheet material as claimed in claim 1 in which the decorative surface of the sheet material is provided with a coating of a material which prevents the decorative surface adhering to the adhesive coated working surface when the sheet is rolled up.
Claim 6
Dependent Claim
121 words
In a sheet material which is applied to a support surface, said sheet material having a decorative surface and a working surface, in which the working surface is provided with a continuous coating of a tacky, pressure-sensitive adhesive, the improvement in which said adhesive coating is provided with a discontinuous layer of resilient, non-adhesive solid particles of a material selected from a foamed organic polymeric material, a natural or synthetic rubber or blends thereof, said particles having the ability to deform under a load and the ability to recover to substantially their original dimensions, after being deformed, and upon application to said supporting surface deform to such an extent as to bring the adhesive coating and the support surface into contact.
Claim 7
Dependent Claim
121 words
In a sheet material which is applied to a support surface, said sheet material having a decorative surface and a working surface, in which the working surface is provided with a continuous coating of a tacky, pressure-sensitive adhesive, the improvement in which said adhesive coating is provided with a discontinuous layer of resilient, non-adhesive solid particles of a material selected from a foamed organic polymeric material, a natural or synthetic rubber or blends thereof, said particles having the ability to deform under a load and the ability to recover to substantially their original dimensions, after being deformed, and upon application to said supporting surface deform to such an extent as to bring the adhesive coating and the support surface into contact.
