Disclosed is a polyester polymer prepared from a reaction mixture comprising a polyacid component and a polyol component that comprises lignin. Residues of lignin are incorporated into the backbone of the polyester polymer. Coatings comprising the same and substrates coated at least in part with such coatings are also disclosed.

A coated article is described, including a substrate with a coating composition applied thereon to provide a coated article with a textured surface. In one aspect, the coated article is a steel rebar used to reinforce concrete. The textured surface provides optimal surface roughness and demonstrates superior pullout strength relative to an uncoated standard.

The present invention relates to a composite product comprising a thermally modified solid wood component coated with a layer of a composite material which composite material comprises thermally modified cellulosic material and a polymer. The invention also relates to a process for producing said composite product.

A release film is provided for supporting an ultrathin ceramic green sheet having a thickness of 0.5 to 1.0 m, and the release film due to containing modified organic particles and an antistatic agent has a slippery releasing surface with a low friction coefficient and hence excellent coatability and releasing properties; resulted in that when the release film is rolled up, the rolled surfaces do not adhere to each other, and when the ultrathin ceramic green sheet is peeled off from the release film, the ultrathin ceramic green sheet due to a relatively small electrostatic force being generated is without breaking; so that the release film contributes to increasing the yield of ultrathin ceramic green sheet.
