Synthetic leather article and method for preparing same

A synthetic leather article, comprising, from top to bottom:

• (A) a top coating layer derived from an internally emulsified polyurethane dispersion comprising a first polyurethane derived from (Ai) one or more first isocyanate components comprising at least two isocyanate groups, (Aii) one or more first isocyanate-reactive components comprising at least two isocyanate-reactive groups, and (Aiii) one or more internal emulsifiers, wherein the internal emulsifiers or residual moieties of the internal emulsifiers are covalently attached to a backbone chain of the first polyurethane;
• (B) a barrier layer derived from an externally emulsified polyurethane dispersion, wherein the externally emulsified polyurethane dispersion comprising one or more external emulsifiers and a second polyurethane derived from (Bi) one or more second isocyanate components comprising at least two isocyanate groups and (Bii) one or more second isocyanate-reactive components comprising at least two isocyanate-reactive groups, wherein the external emulsifiers or residual moieties of the external emulsifiers are not covalently attached to a backbone chain of the second polyurethane;
• (C) a polyurethane foam layer comprising a third foamed polyurethane derived from a solvent-free system comprising (Ci) one or more third isocyanate components comprising at least two isocyanate groups, (Cii) one or more third isocyanate-reactive components comprising at least two isocyanate-reactive groups, and (Ciii) one or more foaming agents;
• and
• (D) a backing substrate.
