Abstract
Abstract A method for producing a multilayer decorative material, wherein a die is provided having one or more raised and depressed areas, the raised areas corresponding to the desired shape of the decorative material; a melt adhesive layer is applied to the raised areas across their surface; an effect layer is applied to the melt adhesive layer; a protective layer or a color lacquer layer is optionally applied to the effect layer; and the multilayer decorative material consisting of the adhesive, effect layer and optional protective layer is removed as a unit from the raised areas, for example by a self-adhesive sheet.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
A method for producing a multilayer decorative material including at least a melt adhesive layer and an effect layer comprising: (a) providing a die having one or more raised and depressed areas, the raised areas corresponding to the desired shape of the deorative material and the die being made of a material from which a melt adhesive layer is easily detachable; (b) applying the melt adhesive layer to the raised areas across their surface; (c) applying the effect layer to the melt adhesive layer; (d) providing a thermally non-activatable transparent protective layer or color lacquer layer on the effect layer; (e) removing from the raised areas of the die the melt adhesive layer, the effect layer and the protective layer or color lacquer layer as a multilayer decorative material with a least the melt adhesive layer exposed.
Claim 2
Independent Claim
137 words
A method for producing a multilayer decorative material including at least a melt adhesive layer and an effect layer comprising: (a) providing a die having one or more raised and depressed areas, the raised areas corresponding to the desired shape of the deorative material and the die being made of a material from which a melt adhesive layer is easily detachable; (b) applying the melt adhesive layer to the raised areas across their surface; (c) applying the effect layer to the melt adhesive layer; (d) providing a thermally non-activatable transparent protective layer or color lacquer layer on the effect layer; (e) removing from the raised areas of the die the melt adhesive layer, the effect layer and the protective layer or color lacquer layer as a multilayer decorative material with a least the melt adhesive layer exposed.
Claim 3
Dependent Claim
14 words
The method according to claim 1 wherein the die is made of silicon rubber.
Claim 4
Dependent Claim
25 words
The method according to claim 1 wherein the melt adhesive layer is strewn on as a particulate material across the die surface, melted and smoothed.
Claim 5
Dependent Claim
24 words
The method according to claim 1 wherein a heat-resistant synthetic layer is applied to the melt adhesive layer before the effect layer is applied.
Claim 6
Dependent Claim
16 words
The method according to claim 1 wherein the effect layer is formed by vaporization and deposition.
Claim 7
Dependent Claim
15 words
The method according to claim 1 wherein the transparent protective layer is a varnish layer.
Claim 8
Dependent Claim
34 words
The method according to claim 1 wherein the multilayer decorative material is removed from the raised areas of the die by means of a self-adhesive sheet applies to the layer furthest from the die.
Claim 9
Dependent Claim
12 words
The method according to claim 7, wherein the self-adhesive sheet is transparent.
