  • the cast inkjet paper described in Patent Document 2 that is assumed to be used in an inkjet printer for home use is mainly composed of silica, which is a bulky pigment, and increases the amount of voids in the coating layer. For this reason, there is a problem that banding occurs due to insufficient ink spreading when recording with an industrial inkjet printer. Furthermore, since silica is used as the pigment, the strength of the coating layer is insufficient for general printing suitability such as offset printing and letter press, and the general printing suitability is poor.

Define the corners.
  • Heavy calcium carbonate in inorganic pigments compared with light calcium carbonate, has a recording layer consisting of a cast coating layer to ensure a sufficient gap for recording with an (industrial) ink jet printer, and (industrial) ink jet recording. This has the effect of retaining ink on the surface layer.
  • SBL also has the effect of suppressing ink from penetrating into the recording layer in (industrial) ink jet recording and retaining the ink on the surface layer. Further, SBL ensures general printability such as offset printing and letter press. In general printing, ink is brought into contact with a printing object to be transferred, so that the printing object needs a certain surface strength. SBL also has the effect of increasing the glossiness of the printed portion. Moreover, when the surface of the cast drum is pressure-bonded and dried to give a gloss finish, the releasability (peelability) from the cast drum is excellent. Further, since SBL has an effect of suppressing ink permeation in the internal direction of the recording layer, when SBL is increased, the ink tends to spread in the plane direction (direction along the surface) of the recording layer.
  • cast coated paper has a high surface water repellency, so that it prevents the ink from penetrating into the recording layer too much. If excessive ink is retained on the surface layer, the dried and solidified ink is granular on the surface layer. As a result, the definition of the recorded image decreases. In addition, it may cause poor drying of the ink. In addition, if the ink is retained on the surface layer but spreads too much in the plane direction, unintended ink mixing occurs, and the dried and solidified ink becomes grainy on the surface layer, which may reduce the fineness of the recorded image. is there. Therefore, by defining the contact angle, color developability is improved in (industrial) ink jet recording, and banding (stretching) and beading (graininess) can be suppressed.
  • Banding is a print defect in which a white portion that is not originally printed on a portion of the print portion is formed due to reasons such as ink not spreading in the recording layer, resulting in white stripes.
  • Beading refers to both (i) defective printing in which the ink is dried and solidified in a granular state, and (ii) image unevenness or poor drying. (i) is likely to occur when the ink does not penetrate into the recording layer and does not spread in the plane direction. Hard to be granular. On the other hand, if the ink spreads too much in the plane direction, the ink overlaps particularly in the mixed color portion, and it becomes easy to cause unevenness in the image or poor drying, and this becomes the printing defect (ii). Since (i) occurs when the ink contact angle is too high, and (ii) occurs when the ink contact angle is too low, it is necessary to define the upper and lower limits of the contact angle.

  • Kaolin has the effect of improving the smoothness of the recording layer and improving the glossiness of the blank paper.
  • the amount of kaolin is large because the internal voids are small and it is flat and easy to form a dense recording layer. The voids in the recording layer are reduced, and the above-described beading (graininess) is likely to occur in (industrial) ink jet recording.

On the other hand, when a release agent such as higher fatty acid calcium, paraffinic, zinc stearate, special surfactant, carnauba wax, ethylenebisstearic acid amide is used, the contact angle tends to exceed 40 degrees.
