A method for producing a breathable film based on polyvinyl chloride (PVC), including the following steps. Preparing a paste-like compound including a first fraction composed of PVC, a second fraction composed of a foreign material, and a third fraction composed of adjuvants and/or additives that that are mixed together to form the paste-like compound, applying the paste-like compound to a base, and drying and gelling the paste-like compound, which has been applied to the base, through the addition of heat, thus forming the film in which pores extending from the one surface of the film to the other are formed, which give the film breathability.

The present disclosure provides an artificial leather structure, comprising a woven layer, a porous elastomer layer disposed on the woven layer and a nonwoven layer disposed on the porous elastomer layer. The porous elastomer layer is adhered to the woven layer and the nonwoven layer.

A composite skin material for a vehicle wherein a synthetic leather includes a surface resin layer having a plurality of openings, an adhesion layer present on the rear surface of the surface resin layer, and a fibrous base material present on the rear surface of the surface resin layer across the adhesion layer, and the adhesion layer is present only at the adherend part, except for the plurality of openings, in the rear surface of the surface resin layer, and the base material surface of the fibrous base material is bonded to the surface resin layer.

The present disclosure relates to a breathable layered flexible material comprising at least one polyvinyl chloride (PVC) porous layer or a plurality of PVC porous layers and a support layer. The the pores of the PVC porous layer or plurality of PVC porous layers are obtainable by water evaporation of a water-in-oil PVC emulsion. The pores extend from the PVC layer to the support layer providing the material breathability. The disclosure also relates to a method for preparing the breathable layered flexible material. Upholsteries, in particular car upholsteries, comprising the breathable layered flexible material are also disclosed.

The present invention provides a synthetic leather including at least a base (i), an adhesive layer (ii), and a skin layer (iii). The adhesive layer (ii) is formed of a urethane resin composition including a urethane resin (A) produced using an aromatic polyisocyanate (a1) as a raw material and water (B). The skin layer (iii) is formed of a urethane resin composition including an anionic urethane resin (X) having an anionic group concentration of 0.15 mmol/g or less and water (Y). The aromatic polyisocyanate (a1) preferably includes toluene diisocyanate. The urethane resin (A) has an aromatic ring concentration of 0.1 to 2.5 mol/kg.

The present invention provides a synthetic leather including at least a base (i), an adhesive layer (ii), and a skin layer (iii). The adhesive layer (ii) and the skin layer (iii) are both formed of a urethane resin composition including a urethane resin and water, the urethane resin being produced using an aromatic polyisocyanate as a raw material. The urethane resin composition forming the adhesive layer (ii) preferably includes a urethane resin (A) and water (B), the urethane resin (A) being produced using an aromatic polyisocyanate (a1) as a raw material. The aromatic polyisocyanate (a1) preferably includes toluene diisocyanate. It is preferable that the urethane resin (A) include an anionic group and the concentration of the anionic group in the urethane resin (A) be 0.35 mmol/g or less.
