Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
87 words
In a self-adhering transfer material comprising in descending order an upper foil-like or paper-like carrier layer, one or more transferable designed layers, releasably connected to the carrier layer and a lower adhesive layer, wherein the improvement comprises an intermediate layer between the adhesive layer and the one or more design layers, the intermediate layer consisting essentially of a polyester resin hardenable into a permanently elastic formstable layer, said polyester resin being adhesively bondable and compatible with both the adhesive layer and the one or more design layers.
Claim 2
Dependent Claim
87 words

Claim 3
Dependent Claim
32 words
The transfer material of claim 1 wherein the polyester resin of the intermediate layer has been applied in solvents and has not been completely hardened before application of the lower adhesive layer.
Claim 4
Dependent Claim
20 words
The transfer material of claim 1 wherein a primer layer is present between said intermediate layer and said adhesive layer.
Claim 5
Dependent Claim
22 words
The transfer material of claim 3 wherein said primer is a nitro-combination varnish, a screen printing varnish or an acrylic resin varnish.
Claim 6
Dependent Claim
27 words
The transfer material of claim 3 wherein said intermediate layer itself is pigmented and has the same outside dimensions of said primer layer and said adhesive layer.
Claim 7
Dependent Claim
25 words
The transfer material of claim 1 wherein an adhesion promoting agent is used to increase the adhesion between said intermediate layer and said adhesive layer.
Claim 8
Dependent Claim
15 words
The transfer material of claim 6 wherein said promoting agent is a powdery adhesion promoter.
