    摘要： A paper coating composition is disclosed, which comprises:(A) a pigment, and(B) a copolymer emulsion prepared by polymerizing a monomer mixture containing:(i) 5 to 40 wt % of an .alpha.-olefin of the formula:CH.sub.2 .dbd.CH--R.sub.1 wherein R.sub.1 is a hydrogen atom or an alkyl group having 1 to 12 carbon atoms;(ii) 30 to 90 wt % of a vinyl ester of the formula: ##STR1## wherein R.sub.2, R.sub.3 and R.sub.4 are each a hydrogen atom or an alkyl group having 1 to 18 carbon atoms;(iii) 1 to 30 wt % of at least one unsaturated carboxylic acid ester selected from the group consisting of an acrylic acid ester in which the alkyl moiety thereof has 1 to 18 carbon atoms and a methyacrylic acid or dibasic unsaturated carboxylic acid ester in which the alkyl moiety thereof has 1 to 18 carbon atoms; and(iv) 0.1 to 10 wt % of an unsaturated carboxylic acid. The paper coating composition of the invention provides improved printability and printing quality and is particularly useful for gravure printing.

    摘要： Disclosed is a stage device suitably usable in a semiconductor microcircuit device manufacturing exposure apparatus for printing a pattern of a mask on a semiconductor wafer, for supporting and positioning the wafer with respect to plurality of directions. The device includes two plate members coupled to each other with a predetermined distance maintained therebetween. Each plate member has formed therein X, Y and .theta. stages defined by plural cutout grooves. Each stage is resiliently supported by a leaf spring functioning portion formed in the plate member. A Z stage for displacing the wafer in the Z direction is mounted to an outer circumferential part of one plate member, and a measuring mirror operable in combination with a laser interferometer is provided as a unit with the Z stage. Any motion of each stage can be controlled on the basis of the measurement made by using this mirror. The structure of the stage device ensures high precision and high rigidity and, therefore, the Z axis can be set substantially horizontally. Consequently the stage device is suitably applicable to an exposure apparatus to be used with an SOR ring.
