INK JET RECORDING PAPER

摘要

Ink jet recording paper which is so-called plain paper with no coating using a pigment applied to its recording face and is excellent in recorded image density, color reproducibility and waterproofness and surface strength at the printed portion; specifically, ink jet recording paper obtained by applying a coating liquid containing a fluorescent whitening agent, a water soluble binder and a cationic polymer fixer to neutral base paper using wood pulp as a main material; specifically, ink jet recording paper, wherein an ISO brightness of coated paper as measured by a measuring method specified in JIS P-8148 with a xenon flash tube used as a light source is not less than 95 % and its fluorescent intensity is 7 to 15 %, the ink jet recording paper being machine-made using calcium carbonate as a filler and containing 5 to 20 % of base paper ash component through a specified treatment and a mixture in a specified ratio of a specified fluorescent whitening agent and a specified cationic polymer fixer.
