INK COMPOSITIONS FOR GRAVURE PRINTING, BUILDING MATERIALS COMPRISING THE SAME AND MANUFACTURING METHOD THEREOF

摘要

An ink composition for the gravure printing, a construction material containing the ink composition, and its manufacturing method are provided to prevent the viscosity increase due to the use of an inorganic pigment. An ink composition for the gravure printing comprises 10-20 parts by weight of an acrylic resin or monomer; 50-70 parts by weight of an inorganic pigment; and 20-30 parts by weight of an organic solvent. Preferably the acrylic resin or monomer contains an alkyl (meth)acrylate, and the organic solvent is at least one selected from the group consisting of methylisobutyl ketone and methylethyl ketone. A construction tile comprises an inorganic material base(4), and a gravure printing layer(2) comprising the ink composition.
