20250382743 · 2025-12-18 ·

Artificial leathers have a top layer that contains a solid, water-insoluble polyurethane elastomer, a solid, water-insoluble acrylate elastomer, and embedded particles of an encapsulated phase change material. The top layer imparts a desirable cool touch feature to the artificial leather, while also imparting other important physical and tactile properties such as a soft and smooth feel. An artificial leather comprises a backing layer and a top layer bonded directly or indirectly to the backing layer. The top layer comprises, by total weight of the top layer: (i) 25 to 75 weight percent of a solid, water-insoluble polyurethane elastomer; (ii) 10 to 40 weight percent of a solid, water-insoluble acrylate elastomer; and (iii) 1.5 to 30 weight percent of embedded particles of an encapsulated phase change material. The encapsulated phase change material (iii) has a melting or glass transition temperature of 20 to 37 C.
