Abstract
Official abstract text for this publication.
A multilayer structure including (a) a fabric, (b) a polyurethane foam containing a plurality of cells defined therein, wherein the foam contains at least one surfactant, and (c) a skin layer, wherein the skin layer comprises a wetting agent and an acrylic polymer having a glass transition temperature of −20 degree Celsius or less, and the foam resides between the fabric and the skin layer; and the process of preparing the multilayer structure.
First claim
Opening claim text (preview).
What is claimed is: 1. A multilayer structure comprising: (a) a fabric, (b) a polyurethane foam containing a plurality of cells defined therein and at least one surfactant, (c) a skin layer, wherein the skin layer comprises a wetting agent and an acrylic polymer having a glass transition temperature of −20 degree Celsius or less, and the foam resides between the fabric and the skin layer, and (d) a finishing layer, wherein the skin layer resides between the finishing layer and the foam, and the finishing layer comprises a wetting agent, a crosslinked acrylic polymer wherein the acrylic polymer has a glass transition temperature of −20 degree Celsius or less. 2. The multilayer structure of claim 1 , wherein the wetting agent is selected from a silicon surfactant, a fluorine surfactant or mixtures thereof. 3. The multilayer structure of claim 1 , wherein the finishing layer is embossed. 4. The multilayer structure of claim 1 , wherein the multilayer structure is free of organic solvent. 5. The multilayer structure of claim 1 further comprising (e) a release paper, wherein the finishing layer resides between the skin layer and the release paper.
