The invention further relates to articles obtainable by this type of process. ## Claims ### Claim 1 A process for producing high-gloss surfaces on at least one portion of a substrate area, wherein the substrate area is composed of wood or wood-like material and the substrate area is covered with melamine paper, where the steps comprise: a) applying a layer made of a reactive melt to at least one portion of the substrate area covered with melamine paper; b) polishing the applied layer of melt; c) applying at least one lacquer layer to the polished layer of melt by means of a curtain-coating process; and d) hardening the layer structure applied. ### Claim 2 (depends on 1) The process as claimed in claim 1, wherein the reactive melt is based on a polyurethane. ### Claim 3 (depends on 1) The process as claimed in claim 1, wherein the melt is applied in step a) by means of a roll apparatus comprising at least one metering roll and an applicator roll rotating in a direction of rotation. ### Claim 4 (depends on 3) The process as claimed in claim 3, wherein the applicator roll rotates with a velocity in the range from 5 to 60 m/min. ### Claim 5 (depends on 4) The process as claimed in claim 4, wherein the applicator roll rotates with a velocity in the range from 10 to 25 m/min. ### Claim 6 (depends on 3) The process as claimed in claim 3, wherein the melt applied in step a) is polished by a polishing roll rotating in opposition to the direction of rotation of the applicator roll. ### Claim 7 (depends on 6) The process as claimed in claim 6, wherein the polishing roll rotates with a velocity in the range from 1 to 30 m/min. ### Claim 8 (depends on 7) The process as claimed in claim 7, wherein the polishing roll rotates with a velocity in the range from 1 to 6 m/min. ### Claim 9 (depends on 1) The process as claimed in claim 1, wherein the melt applied in step a) comprises an abrasive material. ### Claim 10 (depends on 1) The process as claimed in claim 1, wherein the lacquer layer to be applied in step c) comprises a pourable UV-curing high-gloss lacquer. ### Claim 11 (depends on 1) The process as claimed in claim 1, wherein prior to step c) at least one first lacquer layer comprising a UV-curing lacquer is applied with the aid of a roll, by way of spray equipment, or by means of ink jet. ### Claim 12 (depends on 1) The process as claimed in claim 1, wherein step c) uses a wet-on-wet method. ### Claim 13 (depends on 1) The process as claimed in claim 1, wherein prior to step d) a waiting time is observed for hardening. ### Claim 14 (depends on 1) The process as claimed in claim 1, wherein the substrate area covered with melamine paper is an element surface of a laminate element, of a parquet element, or of a floorboard element, of a panel, or of a veneer, furniture, or an item of furniture.
