Abstract

Abstract A laminated structure having a surface to which objects adhere upon application to the surface of the lamination and which objects may be removed from the surface and readhered thereto repeatedly over a long period of time. The lamination comprises an adhesively coated supporting member, a material impregnated with a pressure sensitive plastic adhesive, the material having open interstices in which the plastic adhesive is retained overlying and secured to the adhesively coated supporting member and a plastic adhesive film on the exposed surface of the underlying impregnated material. The film is believed to inhibit curing of the impregnant, and the plastic impregnant maintained in a substantially uncured flowable condition. Upon the application of an object to the surface film it is believed that the pressure exerted causes the film to be interrupted and an amount of the uncured plastic impregnant to flow to the surface of the film, thereby providing a surface to which the object may be removably adhered. The surface of the lamination is capable of being washed with soap and water to remove accumulations of dust, dirt or other material which pressure sensitive adhesive coatings normally attract. Such washings maintain both the appearance and the functional adhesiveness of the laminate over a very long period of time.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 32 words
A laminated display board in accordance with claim 1 wherein said first-mentioned tacky adhesive is an uncured plastic adhesive and said permeable sheet means comprises a plurality of fibers defining interstices therebetween.
Claim 2
Dependent Claim 35 words
A laminated display board in accordance with claim 2 wherein said film is impermeable so as to act to inhibit curing of the underlying uncured plastic adhesive and said sheet means is a textile material.
Claim 3
Dependent Claim 40 words
A laminated display board in accordance with claim 3 wherein said film is formed of said tacky uncured plastic adhesive in its dried form whereby said surface is in a low tack state until pressure actuated to rupture said film.
Claim 4
Dependent Claim 27 words
A laminated display board in accordance with claim 4 wherein a rigid frame surrounds the marginal edges of said laminated structure and said backer board is rigid.
Claim 5
Dependent Claim 31 words
A laminated display board in accordance with claim 4 wherein said tacky adhesive is in an uncured form and said film adhesive is in a dried form of the same material.
Claim 6
Dependent Claim 32 words
A laminated display board in accordance with claim 3 wherein said film is water cleanable and renewable over long time periods and said highly tacky adhesive is a pressure sensitive polyvinyl adhesive.
Claim 7
Dependent Claim 27 words
A laminated display board in accordance with claim 2 wherein said adhesives are selected from the group consisting of polyvinyl acetate acrylic copolymer and polyvinyl acetate homopolymer.
