Abstract:
PURPOSE: To improve a grease insensitive effect of a photographic print layer of prototype plate for a flat plate printing and to prevent publications from the filth of the ground by a method wherein a specific acetylene derivative is contained in a photographic print layer.
CONSTITUTION: Approximately 0.1W20wt% of more than one kind of acetylene alcohol (for example: propargyl alcohol) or acetylene glycol (for example: 1.4- butynediol) is contained to form a photographic print layer in which an inorganic pigment such as titanium oxide is dispersed in a bonding agent such as a acryl resin, by means of a precoated layer in a prototype plate for a direct drawing type flat plate printing formed on a supporting body.
