INK SET FOR INKJET RECORDING AND METHOD FOR FORMING IMAGE

PROBLEM TO BE SOLVED: To prevent the tinting of an image containing composite black formed by inkjet recording when the image fades with ozone. SOLUTION: An ink set for inkjet recording has a yellow ink, a magenta ink and a cyan ink. The maximum difference between decreasing rates (%) of OD (optical...

Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the tinting of an image containing composite black formed by inkjet recording when the image fades with ozone. SOLUTION: An ink set for inkjet recording has a yellow ink, a magenta ink and a cyan ink. The maximum difference between decreasing rates (%) of OD (optical density) values in each component (a yellow component, a magenta component and a cyan component) for each of temperature and humidity conditions is regulated to ≤10 even under any temperature and humidity conditions when ozone resistance evaluation tests are carried out for a composite black patch formed on glossy paper using the yellow ink, the magenta ink and the cyan ink under four kinds of temperature and humidity conditions adapted to the actual environment.
