<P>PROBLEM TO BE SOLVED: To provide a color-developing sheet for pressure-sensitive copying, which is excellent in color development, pressure and contamination resistance, and general printability. <P>SOLUTION: Pressure-sensitive paper is provided with a capsule layer, that contains a capsule containing an electron donating developer and a hydrophobic liquid as core materials, on a support, wherein the capsule layer contains cellulose nanofibers. In particular, the capsule layer reveals an excellent effect by using a cellulose nanofiber having a width of 0.5-20 nm and a length of 0.1-15 μm. <P>COPYRIGHT: (C)2011,JPO&INPIT |
