Abstract
Printed matter, in which an image is recorded on a clear film with a white ink containing a white coloring material and at least one urethane resin as a resin fixative and having a degree of white shielding of 50 or more.
Claims8
A recording method, comprising:
- recording an image on a clear film with a white ink containing a white coloring material and a combination of at least one urethane resin and a resin other than the at least one urethane resin as a resin fixative and having a degree of white shielding of 50 or more, and the resin other than the at least one urethane resin including an acrylic styrene resin or a polyethylene resin,
- wherein the degree of white shielding is expressed by (L* value−65)/integrated transmittance×1000, with L* being L* in a L*a*b* three-dimensional space instituted by CIE and measured by a colorimeter, and L* is in the range from 0 to 100 not having units,
- light passing through the printed matter is measured with a spectrophotometer in a visible light region having a wavelength in the range of 380 nm to 700 nm at 1 nm intervals,
- measured values of the light passing through the printed matter are outputted in the form of 0% to 100%;
- the measured values are integrated to provide the integrated transmittance at the wavelength in the range of 380 nm to 700 nm;
- and
- the integrated transmittance ranges from 0 to 32,000, wherein 0 indicates complete shielding and 32,000 indicates complete transmission.
