Abstract

PURPOSE: To obtain a material for an offset master superior in printing resistance, by coating an emulsion of conductive ZnO and a resin on a water resistant paper base of elongation in water not more than a specified value and drying it to form a photosensitive layer.
CONSTITUTION: Conductive ZnO containing In, Al, Sn, or the like metal element and having 10-3W10-4Ωcm volume resistivity under 180kg/cm2, and an acrylic resin or vinyl acetate resin are mixed in 1:1W6:1 ratio to form an emulsion, and this 5W50g/m2 emulsion is coated on a paper base of elongation immersed in water ≤2.5% and dried to form a photosensitive layer for an offset master material. The offset master made using this material has superior resistance to printing, does not curl in etching of an image, and it can be easily set.
