    • Toner particles of an intimate mixture of 25 to 75% by weight of substantially colorless, inert, nonelectroscopic spheroidal-shape polymer particles of size distribution in the range of greater than 5 to less than 60 .mu.m, not more than 15% of the polymer particles being less than 10 .mu.m or greater than 50 .mu.m equivalent spherical diameter, and 75 to 25% by weight of colorant particles having a size distribution within the range of 0.2 to 30 .mu.m and not more than 50% of the colorant particles being less than 1 .mu.m particle size. Ionic copolymer spheroidal particles are preferred. The toner particles are useful for color development of tacky areas by depositing and distributing the toner particles by means of a pad, including an applicator apparatus comprising a housing for toner, a free moving weight in the housing for agitating the toner, means to release toner from the housing, and at least two hinged pads mounted on the housing.
    • 25至75重量%的基本上无色,惰性的非电光球形聚合物颗粒的均匀混合物的调色剂颗粒,其尺寸分布在大于5至小于60μm的范围内,不超过15%的聚合物 颗粒小于10微米或大于50μm的当量球形直径,和75至25重量%的着色剂颗粒,其尺寸分布在0.2至30微米范围内且不超过50%的着色剂颗粒 粒径小于1μm。 离子共聚物球形颗粒是优选的。 调色剂颗粒可用于通过用垫沉积和分配调色剂颗粒来显色粘性区域,包括涂布装置,包括用于调色剂的壳体,用于搅拌调色剂的壳体中的自由移动重量,用于释放调色剂的装置 以及至少两个安装在壳体上的铰接垫。

    • Process for providing improved solvent resistant surfaces of relief flexographic printing plates prepared by imagewise exposure and liquid development of the unexposed areas of a layer of photosensitive elastomeric composition comprising a high molecular weight butadiene/acrylonitrile copolymer and a monomeric compound wherein, optionally after drying, the developed surface is, in either order, (1) postexposed to actinic radiation, and (2) contacted with two successive aqueous halogen solutions, first, 0.01 to 3.5% by weight aqueous bromine solution for about 15 seconds to 20 minutes or 0.2 to 10% by weight aqueous iodine solution for about 1.0 to 10 minutes, followed by chlorine solution equivalent to that supplied by an aqueous solution, 0.01 to 1.0 molar in NaOCl and 0.012 to 1.2 molar in HCl, for about 15 seconds to 5 minutes.
