The invention provides a composition for forming a hydrophobic material, the composition being made by combining: a perfluorinated amine compound comprising at least two amine moieties, such as a compound made by combining a straight or branched chain C.sub.1-10 alkyl amine having at least two amine groups per molecule, with a straight or branched chain C.sub.1-12 perfluorinated carboxylic acid confining at least one COOH group per molecule; an epoxy compound comprising at least two epoxy moieties; a lubricant, such as a perfluorinated polyether; a population of nanoparticles; and a solvent. Hydrophobic materials formed by evaporation of the solvent from such a composition are also provided as are intermediates excluding the lubricant which are used in the formation of such compositions. Such compositions are used in the formation of hydrophobic and particularly superhydrophobic surfaces. Advantageously these compositions are useful to form robust surface coatings that are resistant to mechanical wear.

A matte synthetic paper is a biaxially oriented polypropylene synthetic paper having a thickness of 25 to 300 m, and includes a printing surface layer as an outermost paper layer. Moreover, by adding a mist flour or a thermoplastic elastomer, the haze and gloss of the printing surface layer can be improved. According to Tappi T480, the printing surface layer having gloss of 15 to 50% is suitable to be printing paper.
