Use of a component having an at least partially curved surface with a microstructuring composed of structuring elements at least in the region of the curvature, wherein the article has a removal direction which, in the case of side faces of the microstructuring elements (11 and 13) that are oriented parallel to one another, is defined by the direction parallel to these side elements, and if the side elements (11 and 13) of the microstructuring elements are not oriented parallel to one another, is determined by the direction in which it is possible to remove the article with microstructuring with a minimum expenditure of force from a mould in which this article has been moulded, wherein (i) the structuring elements are oriented parallel to one another independently of the curvature, (ii) the structuring elements each have a face which faces away from the surface of the article and which is of equal size to the other microstructuring elements, and (iii) the respective distance between the respectively adjacent side faces (11, 13) of the structuring elements is the same, - when these structuring elements lie jointly in one of the planes in which the removal direction also lies and - the distance is measured on a straight line which in each case runs parallel to the tangent which lies on the distance centre point between the respective structuring elements, and wherein the tangent and - the straight line which runs parallel thereto and on which the measurement is performed are situated in such a way as to produce the shortest possible distance which touches the two adjacent structuring elements and - which ends at that point on at least one of the side faces and which is furthest away from the article, as fluidized bed for discrete amounts of a liquid, preferably of a liquid having a surface tension ≥ 60 mN/m, preferably ≥ 68 mN/m, wherein the discrete amounts of the liquid move on the microstructuring. wherein the article has a removal direction which, in the case of side faces of the microstructuring elements (11 and 13) that are oriented parallel to one another, is defined by the direction parallel to these side elements, and if the side elements (11 and 13) of the microstructuring elements are not oriented parallel to one another, is determined by the direction in which it is possible to remove the article with microstructuring with a minimum expenditure of force from a mould in which this article has been moulded, wherein (i) the structuring elements are oriented parallel to one another independently of the curvature, (ii) the structuring elements each have a face which faces away from the surface of the article and which is of equal size to the other microstructuring elements, and (iii) the respective distance between the respectively adjacent side faces (11, 13) of the structuring elements is the same, -
