The present invention provides a synthetic leather at least including a base fabric (i), an intermediate layer (ii), and a skin layer (iii), in which the intermediate layer (ii) is formed of a moisture-curable hot-melt urethane resin composition containing a hot-melt urethane prepolymer (A1) having an isocyanate group and a foaming agent composition (A2), the skin layer (iii) is formed of an aqueous urethane resin composition (Z) containing a urethane resin (X) and an aqueous medium (Y), and the urethane resin (X) is a reaction product obtained by using a polyol (b1), a reactive silicone (b2) having a functional group which reacts with an isocyanate group, and a polyisocyanate (b3) as essential raw materials.

The present disclosure provides layered collagen materials comprising one or more collagen/polymer matrix layers. The collagen/polymer matrix layer(s) are formed of a collagen blended with one or more polymers. The collagen blended within the polymer(s) can be dissolved within the polymer(s). The one or more collagen/polymer matrix layers can be attached to a substrate layer, for example a fabric layer.

The present invention is to provide a method for manufacturing synthetic leather in which, after obtaining a thickened liquid by adding a thickening agent (B) with an oxyethylene group content of 210.sup.2 mol/g or less to an aqueous urethane resin composition containing an aqueous urethane resin (A) having an acid value of 0.01 mgKOH/g or higher in a range of 0.01 to 30 parts by mass relative to 100 parts by mass of the aqueous urethane resin (A), the thickened liquid is coated on a base and coagulated with a coagulating agent (C) containing a metal salt (c-1). As the thickening agent, it is preferable to use one or more kinds of thickening agent that is selected from the group consisting of a cellulose thickening agent, an acryl thickening agent, and a urethane thickening agent. Furthermore, as the metal salt (c-1), calcium nitrate is preferable.

The invention relates to a waterproof membrane for building applications comprising at least one support carrier and at least one layer of a cross-linked coating composition comprising at least one polyurethane. The invention also relates to a waterproof membrane comprising at least one support carrier and at least one layer of a cross-linked coating composition comprising at least one polyurethane, an optional pre-coating layer to facilitate the manufacturing process, and to join the support carrier with the cross-linked coating composition in the most optimal and durable manner to achieve good surface appearance and chemical bonding between reinforcing carrier and crosslinked polyurethane coating.
