    摘要: A protective film for polarizers, including a cellulose resin having an acyl substituent with from 2 to 4 carbon atoms and having a degree of acyl substitution of from 2.1 to 2.7, which satisfies 25≦Re≦100 and 50≦Rth≦300 and in which the cellulose resin contributes to expression of at least 40% of the Re in the film.

    摘要: A self-dispersing graft-copolymer capable of self-dispersion in a high-electrical insulating carrier liquid to form grains therein. The graft-copolymer is combined with a pigment or dye to provide a self-dispersing solid colorant, which is suitable as a toner or toner supply for a liquid developing agent for electrostatic photography. The colorant is also applicable to a printing ink, an ink for an ink-jet system or a coating paint composition. The colorant well self-disperses in a carrier liquid to form well dispersed grains therein without the necessity of mechanical dispersing means.
