Zusammenfassung:	PURPOSE:To improve the antiblocking performance, abrasion resistance and heat resistance by adding a prescribed quantity of the inorganic minute particle fillers into the slide preventing varnish in which the aqeous sticking agent and the alkali-soluble water-soluble resin having a certain glass transition temperature are compounded in each prescribed ratio. CONSTITUTION:Nonslip varnish is adjusted by compounding 40-100 wt. parts of alkali-soluble water-soluble resin having a glass transition temperature of 80 deg.C or more, e.g., styrene/maleic acid copolymer having a molecular weight of 5,000-60,000 into 100 wt. parts of aqueous sticking agent such as ethylene/vinyl acetate copolymer emulsion. Further, the inorganic minute particle fillers, e.g., silica powder having a particle diametre of 1-20 mu is added in 2-10 wt.% (solid portion) into the nonslip varnish. After this varnish is applied to the surface of a paper container, etc., a corrugated board is formed by a corrugator machine. With this constitution, the antiblocking performance, abrasion resistance and heat resistance can be improved.
