"Valuable papers, such as checks, promissory notes, money or printing papers used in wallpaper laminates, must be resistant to burning. For this reason, different flame retardants are used in papers. However, generally, the flame retardants used negatively affect printability by creating a hydrophobic surface. For this reason, it is thought that the combination of flame retardants with a filler that will positively affect the printability of paper will be more suitable for such printable papers. For this purpose, this work aimed to obtain paper with good printability and delayed ignition properties by using calcium carbonate, which is a good paper filler, and tin oxide, which is a flame retardant. In this study, starch-based paper coating formulations containing calcium carbonate and tin oxide individually and in combination in equal amounts were prepared and applied on office paper. Color, gloss, contact angle and flame retardancy properties of the produced papers were determined using a spectrophotometer, a glossmeter, a goniometer and LOI, respectively. Prints were made on the the obtained papers with the IGT C1 offset test printing machine, and the color and gloss properties of the prints were determined. As a result, it was determined that the flame retardancy properties of the papers were significantly increased with the tin oxide filler, while the combination of calcium carbonate and tin oxide improved both the printability and flame retardancy properties."
