Title: Method for manufacturing toilet paper patterned with watermark
Inventor: SANO TAKEO
IPC: A47K10/16
Filed: 2020-04-17
Abstract: To solve the problem of conventional toilet paper rolls on which printing is applied for visual differentiation, where the printing is performed using ink having hue differing from that of ground color and pattern types are limited in a state in which difference exists in hue only.SOLUTION: Toilet paper having freeness of 420 to 500 mLcsf, basis weight (per one ply) of 14 to 20 g/m2, and paper thickness (per one sheet) of 70 to 130 μm is patterned by transfer printing of aqueous pigment ink. The paper has sufficiently transparent ground color of a watermark pattern and the ink is fixed on a surface of the paper. When the printing is performed using ink having higher viscosity and pigment concentration, a blot and crush of ink are inhibited and a pattern part having a clear and deep outline is formed. Anxiety of being easily peelable exists but, unexpectedly, the pattern part is hardly peeled off, which is thought to be due to a characteristic of the paper side. Accordingly, the paper can be patterned with a watermark beautifully.SELECTED DRAWING: Figure 1
