Abstract: An object of the invention is to provide a finely cut paper product exhibiting a good workability in the production of a paper-resin composition comprising a mixture of a resin and a natural fiber, and improve the fluidity of an ecologically sound paper-resin composition using the finely cut paper product, so as to improve the moldability thereof when the composition is subjected to a working such as injection molding. An other object thereof is to restrain the generation of yellowing or the generation of an odor. The finely cut paper product for use in mixing with resin according to the invention is obtained by pulverizing neutral or alkaline pigment-free coated paper which comprises 70 to 100% by mass of hardwood bleached chemical pulp, 0 to 20% by mass of softwood bleached chemical pulp and 0 to 20% by mass of an inorganic filler, and has an ISO brightness of 70% or more.

Abstract: An ink jet printing paper which has a degree of bulk equal to or higher than that of non-coated paper, retains the same quality as that of coated type sheet with respect to surface smoothness, sharpness of print images, ink absorbability and water resistance, and shows improved ink strike-through and cockling while being bulky. The ink jet printing paper has an ink receiving layer provided on the base paper with the base paper containing synthetic fiber having a branched form.
