Art paper with surface microstructures and preparation technology thereof

The invention provides art paper with surface microstructures. The art paper is characterized by comprising a paper layer, wherein a microstructure layer is arranged on the surface of the paper layer; a plurality of microstructures are uniformly and densely distributed on the microstructure layer. The art paper has the beneficial effects that the paper surface is provided with the microstructures, the microstructures can be used as spaces for containing pigment, and the interior of each microstructure is provided with a hydrophilic surface layer for effectively adsorbing pigment liquid; even if the art paper is put on the plane with certain slope, and the amount of water dipping is more, the accumulation of pigment liquid at the lower part is avoided; the thickness of each microstructure is equal to 1/5-1/3 of thickness of the paper layer, and the distance between the adjacent microstructures is equal to 50-150% of width of each microstructure; the sense is similar to the sense on the surface of common art pa
