摘要： Described herein is an aqueous coating composition including at least one binder, at least one sustainable pigment selected from recycled carbon black or coffee grounds or tea, at least one solvent and optionally at least one crosslinking agent and/or at least one additive. The use of the sustainable pigments in the aqueous coating results in colored coatings on substrates, such as flexible foam substrates, having a high optical quality as well as good mechanical properties. Also described herein is a process for producing the aqueous coating composition and a method for coating a substate using the aqueous coating composition. Finally, described herein is a substrate bearing a coating produced by the method.

摘要： Described herein are post-coating, in-mold coating and transfer coating methods for producing a coating on a substrate by using a liquid coating composition including at least one binder and at least one naturally occurring pigment. Also described herein is a coating produced by the methods. The coatings produced in this way not only have a high-level optical appearance and good tactile qualities but also outstanding mechanical resistance, flexibility and weathering stability. The methods can therefore be used to particularly good effect in those sectors imposing equal demands on optical quality, mechanical stability and flexibility of coating layers being present on the substrate. With particular preference, the methods are appropriate for application in the footwear industry, in particular in the coating of shoe parts, such as soles, composed of flexible foam substrates or in the production of shoe uppers based on leather or synthetic materials.
