Synthetic resin leather includes a base material, and a skin layer that is stacked on the base material and is made of a synthetic resin capable of being elastically deformed. Multiple micro recess parts are intermittently and regularly formed on a surface of the skin layer. The multiple micro recess parts form multiple bottom face parts that are located at a substantially constant depth from the surface of the skin layer, and multiple inner side face parts that extend from the surface of the skin layer to the multiple bottom face parts and are capable of being elastically deformed.

Coated nonwoven fibrous mats, building panels, and methods for making the same are provided. A coated nonwoven fiber mat includes a nonwoven fibrous mat having a continuous barrier coating on a surface thereof. The continuous barrier coating includes a set composition of gypsum and a binder. A building panel includes a panel core associated with a coated nonwoven fiber mat. A method of making a coated nonwoven fibrous mat includes depositing a composition of water, gypsum stucco, and a binder onto a surface of a nonwoven fibrous mat and setting the composition to form a continuous barrier coating.

A conveyor belt includes a bottom fabric layer having a lower first surface forming a backside of the conveyor belt and an upper first surface, wherein the lower first surface is impregnated with an impregnation having: a) one or more thermoplastic polyolefins selected from the group consisting of ethene homopolymers, propene homopolymers, ethene/-olefin copolymers, propene/-olefin copolymers and terpolymers of ethene with two or more different -olefins; and b) a thermoplastic polymeric dispersing agent containing repetitive units derived from at least one ethylenically unsaturated monomer of a comparatively lipophilic nature and from at least one ethylenically unsaturated monomer of a comparatively hydrophilic nature and earring an anionic carboxylate group. A process for the manufacture of such belts includes applying the thermoplastic polyolefin(s) and the thermoplastic polymeric dispersing agent as an aqueous dispersion and heating the lower first surface having the dispersion applied thereonto.
