摘要： Multicolor printing on a high speed web-fed press with cold-set ink increases production efficiency over that of a press with dryers. For this purpose, newsprint is used because of its good oil absorptiveness, however, the printing quality is not satisfactory. A coating including needle form pigments, the average oil absorptiveness of which is more than 65 cc/100 g, was applied on the base paper, and coated paper for the high speed press was produced. The present invention increases the reproducibility of dots and sharpness of print patterns compared comparing to usual newsprint without decreasing the handling efficiencies

摘要： A production method of microcapsules using a copolymer including at least three types of monomers including 50 to 90 by weight of acrylic acid, 2 to 40% by weight of an acrylamidealkylsulfonic acid such as acrylamidepropanesulfonic acid, and 2 to 15% by weight of an alkylacrylate such as butylacrylate as an anionic water-soluble polymer as an emulsifier and a reaction promoter for a core substance of the microcapsules, whereby obtaining microcapsules for use in pressure-sensitive copy paper having wall films of an amine-aldehyde condensation polymer which reduces spot staining generated when the capsules are used in pressure-sensitive copy paper by reducing coarse particles present in traces in the microcapsule slurry.
