Frictionizing composition

Abstract

There is disclosed a frictionizing composition for imparting long-term anti-slip properties to the surface of a paper product comprising an aqueous sol of colloidal silica, glycerin, and at least one agent selected from the group consisting of N-methyl pyrrolidone, N,N-dimethyl acetoacetamide, urea, sorbitol, fructose and dextrose. The composition remains fluid, even after prolonged exposure to drying conditions, and thus is readily dispersible in water for easy cleanup of residue from apparatus and the work environment.

What is claimed is:  
     
         1 . A non-skid surface composition consisting essentially of an aqueous suspension of glycerine with at least one material selected from the group consisting of colloidal silica and alumina, and wherein the ratio of said material to glycerin is between about 1:1 to 5:1and further including sorbitol.  
     
     
         2 . A frictionizing composition comprising: 
 (a) an aqueous sol of colloidal silica;    (b) glycerin; and    (c) sorbitol.    
     
     
         3 . A frictionizing composition comprising: 
 (a) an aqueous sol of colloidal silica;    (b) glycerin; and    (c) urea.    
     
     
         4 . A frictionizing composition comprising: 
 (a) an aqueous sol of colloidal silica;    (b) glycerin;    (c) urea; and    (d) sorbitol.    
     
     
         5 . A method of increasing the coefficient of friction of the surface of a cellulosic substrate comprising the steps of applying a non-skid surface composition consisting essentially of an aqueous suspension of glycerin, sorbitol, and at least one material selected from the group consisting of colloidal silica and alumina, and wherein the ratio of said material to glycerin is between about 1:1 to 5:1, to the surface of said substrate and evaporating water therefrom.
