The present invention relates to a composition comprising hedge-hog shaped particles, at least one binder, and at least one hydrophobizing agent and/or at least one hydrophilizing agent, a method for controlling the wettability of substrate surfaces using these compositions, as well as a material comprising these compositions.

A process for application of metal on a substrate surface comprises applying a mixture of a solvent, a polymerizable monomer, and a photoinitiator on a substrate surface, wherein the photoinitiator does not form two phases together with the monomer and the solvent, i.e. it forms an amorphous mixture without any crystals. The monomer is able to polymerize to a polymer comprising at least one carboxylic group. Thereafter the solvent is evaporated. Polymerization is induced by irradiating the applied dried mixture. Ions are applied and reduced to metal and thereafter further metal can be deposited. The method can be used in industrial processes, both 2D and 3D surfaces can be coated with metal. Materials sensitive to standard grafting chemicals and/or polymers containing halogen atoms can be coated.

The present invention relates to a composition comprising hedgehog shaped particles, at least one binder, and at least one hydrophobizing agent and/or at least one hydrophilizing agent, a method for controlling the wettability of substrate surfaces using these compositions, as well as a material comprising these compositions.

Hydrophobic materials, processes for their production, and uses thereof are described. The materials can be made with silica or polytetrafluoroethylene particles embedded into a liquid polymer. The hydrophobic materials are stretchable.

A method for producing a building material includes a first step of applying an undercoat paint onto a surface of an inorganic base material, curing the undercoat paint, and polishing the undercoat paint; and a second step of applying an enamel paint onto the undercoat paint and curing the enamel paint. The undercoat paint contains an undercoat-forming material and a filler. The enamel paint contains an enamel-forming material and a pigment. The enamel-forming material is a solvent-based resin. A content of the filler in the undercoat paint is 40% to 70% by mass in terms of solid content. A content of the pigment in the enamel paint is 1% to 50% by mass in terms of solid content.

A decorative sheet includes a primary film layer, a transparent ridged layer, and a surface protective layer laminated in this order, wherein asperities having ridge parts protruding in a ridged shape are formed on the transparent ridged layer, and the relationship between a film thickness TA of the surface protective layer on a raised portion of the transparent ridged layer and a film thickness TB of the surface protective layer on a recessed portion of the transparent ridged layer satisfies 0.1TA/TB2.0.
