Description

[0001] Cross-reference of related applications [0002] This application claims priority from Korean Patent Application No. 2003-35599, filed with the Korean Intellectual Property Office on June 3, 2003, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a recording medium, and more particularly, to an ink jet recording medium comprising an ink receiving layer coated on the surface of a substrate. [0004] Inkjet printers are widely used because they can provide fast output speed, low cost, and high-definition images. Background technique [0005] Various recording media such as plain paper, special coated paper, and special films have been used in ink jet printers. When the inkjet recording medium includes a hydrophobic substrate formed of polyester such as polyethylene terephthalate, cellulose acetate, etc., a hydrophilic material is coated on the hydrophobic substrate to facilitate the ink recording Fix...
