Abstract
Abstract A transferable enamel sheet and the process for producing it is disclosed, which consists of a carrier film, a release layer applied thereon, a paint or enamel layer and an adhesive layer whereby a neutralization layer of wax-type consistency, preferably carnuaba wax is applied to the release layer which is of the dimethyl-siloxane type (silicone). It is possible to preform two types of transferable enamel sheets. One of them is characterized by the adhesive layer between the neutralization layer and the paint or enamel layer. In this case the enamel paint itself is used as a removal coating, which can immediately be adhered to the surface to be touched up or painted. The other type is characterized by a buffer layer, preferably acrylic resin coated on the neutralization layer and by sharp defined enamel-characters being printed on the buffer layer with an adhesive layer on the outer side to transfer the characters to any surface.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
99 words
A method for the fabrication of a transferable enamel sheet formed as a laminate, comprising the steps of applying a release layer on one side of a web-type carrier sheet, applying a neutralization layer comprising a wax consisting of a mixture of branched and unbranched hydrocarbon chains with an average length of 30 carbon atoms and a COOH group at several places on the chain on the coated side of said carrier sheet, applying a pressure-sensitive adhesive layer on said neutralization layer, curing said adhesive layer, applying an enamel layer on said adhesive layer, and curing said enamel layer.
Claim 2
Independent Claim
99 words
A method for the fabrication of a transferable enamel sheet formed as a laminate, comprising the steps of applying a release layer on one side of a web-type carrier sheet, applying a neutralization layer comprising a wax consisting of a mixture of branched and unbranched hydrocarbon chains with an average length of 30 carbon atoms and a COOH group at several places on the chain on the coated side of said carrier sheet, applying a pressure-sensitive adhesive layer on said neutralization layer, curing said adhesive layer, applying an enamel layer on said adhesive layer, and curing said enamel layer.
Claim 3
Dependent Claim
25 words
A method in accordance with claim 1, further comprising the step of adding solvents with apolar properties to said adhesive before applying said adhesive layer.
Claim 4
Dependent Claim
14 words
A method in accordance with claim 1, wherein said release layer consists of silicone.
Claim 5
Independent Claim
116 words
A method for the fabrication of transferable enamel characters or the like formed as part of a laminated sheet, comprising the steps of applying a release layer on one side of a web-type carrier sheet, applying on the coated side of said carrier sheet a neutralization layer comprising a wax consisting of a mixture of branched and unbranched hydrocarbon chains, with an average length of 30 carbon atoms and a COOH group at several places on the chain, curing said neutralization layer, applying a buffer layer on said neutralization layer, applying enamel characters on said buffer layer, curing said enamel characters, applying a pressure-sensitive adhesive layer on the enamel characters only, and curing said adhesive layer.
Claim 6
Independent Claim
116 words
A method for the fabrication of transferable enamel characters or the like formed as part of a laminated sheet, comprising the steps of applying a release layer on one side of a web-type carrier sheet, applying on the coated side of said carrier sheet a neutralization layer comprising a wax consisting of a mixture of branched and unbranched hydrocarbon chains, with an average length of 30 carbon atoms and a COOH group at several places on the chain, curing said neutralization layer, applying a buffer layer on said neutralization layer, applying enamel characters on said buffer layer, curing said enamel characters, applying a pressure-sensitive adhesive layer on the enamel characters only, and curing said adhesive layer.
Claim 7
Dependent Claim
32 words
A method in accordance with claim 4, further comprising the step of adding solvents with apolar properties to said buffer material before applying said buffer layer, and then curing said buffer layer.
