Description

Eco-friendly and eraseable matte board and its manufacturing method {Circumstance harmony and clearing is superior the lusterless board that making method}

The present invention relates to a matte board, which is environmentally friendly and excellent in eraseability. More specifically, the writable surface layer (matte resin layer) of the matte board has a matte, but also determines the composition of the paint to be excellent in eraseability. It is easy to erase even writing on the surface layer by using board marker. Also, it is possible to suppress the pollution of natural environment by using eco-friendly material of the board material of matte board. The present invention relates to an environment-friendly and eraseable matte board that can reduce human injury.
