ABSTRACT:
Provided herewith is an anti-brick/anti-static composition useful for treating film surfaces. The composition comprises (i) an anionic or cationic surfactant exhibiting anti-static properties, and (ii) a similar charged inorganic particle, e.g., a negatively charged silica or positively charged alumina coated silica, having an average particle size of less than 0.1 micron. Upon coating a film surface with the composition, good anti-static properties are realized without experiencing problems with bricking or blocking of the film. The composition is particularly useful in coating microfilm since it also provides the anti-brick/anti-static properties without deleteriously effecting the viewing capabilities of the film over a wide range of magnifications.
