Patent ID: 8038830

Claim:
A process for producing a synthetic leather comprising the steps of: coating a resin composition for a skin layer of the synthetic leather onto a surface of a matte layer of a release sheet, drying the coating by heating to form a film as the skin layer, then laminating a backing fabric onto the skin layer with the aid of an adhesive to form an assembly, drying and aging the assembly, and then separating the release sheet from the assembly to form the synthetic leather, wherein the release sheet comprises: a matte layer formed by coating a composition for matte layer formation comprising a thermosetting resin, a release agent, and a matting agent as indispensable components, said matting agent comprising at least one of organic and inorganic porous fine particles, said porous fine particles having a mean particle diameter of 0.5 to 20 μm and a specific surface area of 1 to 1000 m 2 /g; and a substrate for supporting the matte layer, wherein said matte layer is a multilayer structure comprising at least two releasable resin layers; the releasable resin layers, except for at least a releasable resin layer in contact with the substrate, contain a release agent comprising a silicone-modified resin or a silicone-containing resin composition; a content of the release agent in the multilayer structure is greater in releasable resin layers that are closer to a surface of the multilayer structure than in the releasable resin layer that is in contact with the substrate; and the releasable resin layers, except for at least the releasable resin layer in contact with the substrate, further comprise a leveling agent.
