LEATHER WITH ALTERATION OF SURFACE COLOUR DEPENDING ON TEMPERATURE AND METHOD FOR PRODUCING THE SAME

摘要

The present invention relates to a leather with a change in surface color as a function of temperature, the leather in question comprising at least one leather base material layer and a lacquer layer, the lacquer layer in question comprising at least one first lacquer layer applied to the leather base material layer in question and one to the relevant one comprises the first lacquer layer applied functional layer, a means with reversible heat-sensitive color change being present in the relevant functional layer, so that the relevant functional layer changes color when a temperature of 30-80 ° C. is reached. The present invention also relates to a method for producing the leather in question. The leather in question is used in surface materials for motor vehicle seats, etc., when the temperature of the leather in question reaches a certain temperature within a range of 30-80 ° C, the functional layer undergoes a color change and the user to a currently excessively high temperature attention is drawn to the leather.
