Abstract
The present invention relates to a method of making an elastomeric skin (1) wherein droplets of at least one first skin forming composition (2) are applied onto a mould surface to form a layer of the first skin forming composition thereon and wherein one or more second skin forming compositions (4) are applied at least partially onto the back of the layer of said first skin forming composition (2) to produce the skin (1). In order to obtain a special visual appearance when using of differently colored first and second skin forming materials, or in order to reduce the effect of the first skin forming composition (2) on the overall physical properties of the skin (1), the droplets of the first skin forming composition (2) are applied onto the mould surface and are allowed to coalesce to form a non-continuous layer of the first skin forming composition which comprises a plurality of gaps (3). The second skin forming compositions (4) are applied not only on the back of the first skin forming composition (2) but also in these gaps (3). The first skin forming composition preferably forms islands on the mould surface which are interconnected by means of the second skin forming composition…
