Abstract
Abstract A method of producing decal transfers having the steps of printing color on a solvent-soluble separation layer on a solvent permeable backing producing a picture, applying a solvent-soluble cover to the area surrounding the picture, and applying a protective-transfer foil over the picture and the cover. The foil is insoluble in the solvent. The cover dissolves in the solvent during the course of the transfer operation thereby removing any impurities arising in the unprinted area surrounding the picture. A decal transfer consists of a solvent-permeable backing carrying a solvent-soluble separation layer thereon, a printed color picture on the separation layer, a solvent-soluble cover on the separation layer in at least the picture-free areas, and an insoluble protective-transfer foil covering the picture and the majority of the cover.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
77 words
Method of producing decal transfers comprising the steps of printing color on a solvent-soluble separation layer on a solvent-permeable backing producing a picture, applying a solvent-soluble cover to the area surrounding the picture, and applying a protective-transfer foil over the picture and the cover, said foil being insoluble in the solvent; whereby said cover dissolves in the solvent during the course of the transfer operation thereby removing any impurities arising in the unprinted area surrounding the picture.
Claim 2
Dependent Claim
77 words
Method of producing decal transfers comprising the steps of printing color on a solvent-soluble separation layer on a solvent-permeable backing producing a picture, applying a solvent-soluble cover to the area surrounding the picture, and applying a protective-transfer foil over the picture and the cover, said foil being insoluble in the solvent; whereby said cover dissolves in the solvent during the course of the transfer operation thereby removing any impurities arising in the unprinted area surrounding the picture.
Claim 3
Dependent Claim
50 words
A decal transfer consisting of a solvent-permeable backing, a solvent-soluble separation layer on said backing, a printed color picture on said separation layer, a solvent-soluble cover on said separation layer in at least the picture-free areas, and an insoluble protective-transfer foil covering said picture and the majority of said cover.
Claim 4
Dependent Claim
50 words
A decal transfer consisting of a solvent-permeable backing, a solvent-soluble separation layer on said backing, a printed color picture on said separation layer, a solvent-soluble cover on said separation layer in at least the picture-free areas, and an insoluble protective-transfer foil covering said picture and the majority of said cover.
Claim 5
Dependent Claim
26 words
Transfer according to claim 2 wherein, the separation layer (2) and the cover (6) superimposed upon it in the picture-free area consist of the same material.
Claim 6
Dependent Claim
23 words
Transfer according to claims 2 or 3, wherein, the separation layer (2) and the cover (6) consist of materials of differing solution speeds.
Claim 7
Dependent Claim
26 words
Transfer according to claim 2, wherein when using water as a solvent, the cover consists of water-soluble mono-, oligo- or poly-saccharides, polyglycols, polyvinyl alcohols, or soaps.
Claim 8
Dependent Claim
24 words
Transfer according to claim 2 wherein, a gap is allowed between the colour application (3a-3d) and the cover exclusively extending over the pattern-free area.
Claim 9
Dependent Claim
15 words
Transfer according to claim 6, characterised in that, the gap is at least 0.5 mm.
