  • Publication number: 20080314500
    Abstract: The invention relates to process for the preparation of a visual properties-matching multilayer coating sheet comprising the steps of a) determining the visual property data of a surface to be matched in visual properties; b) transmitting the data from step a) to a system configured to receive such data, and determination of the composition data of a coating composition having an acceptable match of visual properties; c) preparing a visual properties-matching coating composition according to the determined composition data; d) providing a base sheet layer optionally having an adhesive layer and a backing layer on one surface; e) applying the visual properties-matching coating composition to one surface of the base sheet layer to form a colour- and/or effect-imparting coating layer; f) optionally, drying the applied colour- and/or effect-imparting coating layer; g) optionally, applying a clear coat layer on top of the colour- and/or effect-imparting coating layer; h) optionally, drying and/or curing the clear

  • Publication number: 20030149164
    Abstract: A paint composition for a removable, decorative coat on a non-porous substrate, such as a car, is described. The paint composition is a pigmented lacquer that forms a film where internal cohesion exceeds adhesion to the substrate. The paint composition contains a binder having a glass transition temperature below 19° C., preferably below 13° C. The modulus of elasticity of the paint film after drying is less than 20 MPa, preferably less than 15 MPa.
