摘要

The invention relates to a process for manufacturing materials in the forms of sheets reconstituting the appearance of natural fine materials, such as reptile skins. According to the invention, the sheet 1 is subjected to a raised impression operation using heat, for example by high-frequency induction, the sheet being pressed into a mould bearing on one face the reverse imprint of the said raised uneven features 8, 8', 9, 9', and the process is characterised in that the said sheet is subjected, prior to its raised impression, to two successive coatings of coloured layers 3, 4 of different shades or colours, the upper or surface layer 4 being provided so as to be modified in certain areas under the action of the pressure and of the temperature rise. Application to the manufacture of articles of fancy leatherwork. IMAGE
