    • Disclosed are inks containing compounds of the formula: ##STR1## where --R.sup.1 is --H or --CH.sub.3--R.sup.2 is an aliphatic, preferably linear hydrocarbyl, radical having 11-23 carbon atoms and containing at least one olefinic double bond, or mixtures thereof, -R.sup.2 being free of terminal double bonds, and--X-- is either (a) --OR.sup.3 O-- in which R.sup.3 is an aliphatic or cycloaliphatic hydrocarbon residue containing from 2 to 10 carbon atoms, or (b) --O(CH.sub.2 CHR.sup.4 O).sub.n -- where R.sup.4 is --H or --CH.sub.3 and n is an integer of from 2-10, or mixtures thereof.Preferably, --X-- is --OR.sup.3 O-- wherein R.sup.3 is --CH.sub.2 CH.sub.2 -- or ##STR2## --R.sup.1 is --CH.sub.3, and --R.sup.2 is a mixture of hydrocarbyl moieties derived from drying oils and is at least in part polyunsaturated, and more preferably, predominantly so. The products are oxidatively curable reactive diluents of exceptionally low viscosity and low volatility which are useful for the preparation of high solids lithographic inks to reduce atmospheric pollution caused by volatile non-reactive solvents. In addition to compounds of the given formula, other esters of drying oil fatty acids with various addition-polymerizable olefinically unsaturated hydroxyl-containing compounds are disclosed. Another way of describing the preferred reactive diluents of the invention is to define them as the mixed esters of a polyol with (1) mixed material drying oil fatty acids and (2) an .alpha.,.beta.-ethylenically unsaturated acid.
    • 公开的是含有下式化合物的油墨:其中-R 1是-H或-CH 3 -R 2是具有11-23个碳原子并含有至少一个烯属双键的脂族优选直链烃基,或其混合物 ,-R2不含末端双键,-X-为(a)-OR3O-,其中R3为含有2-10个碳原子的脂族或脂环族烃基,或(b)-O(CH2CHR4O)n - 其中R 4是-H或-CH 3,n是2-10的整数,或其混合物。 优选地,-X-是-OR 3 O-,其中R 3是-CH 2 CH 2 - 或R 1是-CH 3,-R 2是衍生自干性油的烃基部分的混合物,并且至少部分是多不饱和的, 主要是这样。 该产品是特别低粘度和低挥发性的可氧化固化的反应性稀释剂,其可用于制备高固体平版印刷油墨以减少挥发性非反应性溶剂引起的大气污染。 除了给定式的化合物之外,还公开了其它具有各种可加聚的烯属不饱和羟基的化合物的干油脂肪酸酯。 描述本发明优选的反应性稀释剂的另一种方式是将其定义为多元醇与(1)混合材料干油脂肪酸和(2)α,β-烯属不饱和酸的混合酯。

    • A duplicator system and method are provided for preparing a lithographic master and for producing duplicated copies from the master in a fully automated system. An ink and moisture system is provided for supplying ink and moisture to a master on a master cylinder. During a pre-inking phase, an ink ductor roller is operative for a predetermined duration within variable ranges, as determined by the number of duplicated copies to be reproduced, and a moisture roller is operative to transmit moisture to the inking system. An early moisture circuit is also provided for conditioning the system by supplying moisture prior to a pre-inking phase in those instances wherein there has been a significant delay between the processing of two consecutive masters. Control means including a sensing device is provided for sensing the ambient temperature at an ink fountain and providing an indication thereof at predetermined temperature values. Subsequent to the pre-inking phase and during a normal duplicating operation, in response to an indication of the sensed temperature, the speed of transfer of ink from the ink fountain to the ink form roller is automatically controlled by altering the movement of the ink ductor roller, i.e. by interrupting the ducting action of the ductor roller for preselected time intervals. Thus, as the viscosity of the ink changes in response to the temperature, the control means is effective to vary the ducting pattern of the ink ductor roller such that an amount of ink substantially suited to the temperature situation is applied to the master.
    • 提供了一种复印机系统和方法,用于制备光刻母版,并在全自动化系统中从母版制作复制副本。 提供墨水和湿度系统,用于向主缸上的主机供应墨水和水分。 在预墨水阶段期间,墨水导辊在可变范围内操作预定持续时间,由可再现的复制份数确定,并且湿气辊可操作以将湿气传送到上墨系统。 还提供了早期湿度回路,用于在预处理阶段之前提供水分来调节系统,在那些在两个连续主机的处理之间存在显着延迟的情况下。 提供了包括感测装置的控制装置,用于感测墨斗的环境温度,并以预定的温度值提供其指示。 在预墨水阶段之后和在正常复印操作期间,响应于感测到的温度的指示,墨水从墨斗转移到墨水成型辊的速度通过改变墨水管的运动而被自动控制 辊,即通过中断预定时间间隔的导辊的导管作用。 因此,当墨水的粘度随着温度而变化时,控制装置有效地改变墨水导辊的管道图案,使得基本上适合于温度情况的墨水量被施加到主机。
