Provided is a paper treatment agent in which a polyhydric alcohol as a moisturizer has been mixed, and with which paper that has a favorable texture when pressed strongly against the skin as in the case of blowing the nose or the like, suppresses the moisture absorption and moisture desorption even under the environment of high humidity or low humidity, and retains the sense of use, the moist feeling, and the softness can be obtained.

Novel fluorescent whitening agents, compositions or mixtures thereof with known fluorescent whitening agents, their preparation, and their use. The novel fluorescent whitening agents (FWAs) contain three structural subunits derived from 4,4-diamino-2,2-stilbenedisulfonic acid. The novel compounds and their mixtures with known FWAs show very good effectiveness as fluorescent whitening agents for cellulosic materials, in particular for paper.
