Abstract
Provided is an image forming method including a step of imagewisely applying, onto a base material by an inkjet method, at least two inks containing a polymerizable liquid crystal compound, a chiral compound, and a polymerization initiator and having reflection wavelengths different from each other, such that the total application amount of the inks provides an image area ratio of 50% or more in an image forming region.
Claims7
An image forming method comprising:
- a step of imagewisely applying, onto a base material by an inkjet method, three inks containing a polymerizable liquid crystal compound, a chiral compound, and a polymerization initiator and having reflection wavelengths different from each other, such that the total application amount of the inks provides an image area ratio of 50% or more in an image forming region,
- wherein the three inks are an ink capable of forming a cholesteric liquid crystal layer having a selective reflection wavelength in a red light range (a wavelength range of 620 nm to 750 nm), an ink capable of forming a cholesteric liquid crystal layer having a selective reflection wavelength in a green light range (a wavelength range of 495 nm to 570 nm), and an ink capable of forming a cholesteric liquid crystal layer having a selective reflection wavelength in a blue light range (a wavelength range of 420 run to 490 nm), respectively, and
- the three inks differ from each other in at least one of the kind of polymerizable liquid crystal compound or the content of polymerizable liquid crystal compound.
