[9] LUDOX AMŽ, manufactured by Du Pont, is an example of an
aluminate-modified silica colloid useful in the Miranda composition
(id., 9:21-23).
[10] The latex can be any synthetic or natural latex (id., 10:2-3).
[11] The alcohol can be a glycol or polyhydric alcohol, e.g., glycerine or
diethylene glycol (id., 11:15 to 12:19).
[12] The colloidal silica, latex and alcohol can be added in any order to
water (id., 13:18-19).
[13] In one embodiment, the amount of latex in the aqueous composition is
from 1 to 50%, i.e., 10,000 to 500,000 ppm (id., 11:9-11).
[14] In another embodiment, one part of the aqueous composition is
diluted with from 1 to 20 parts water (id., 13:25-26).
[15] An aqueous composition containing 1% latex diluted with 20 parts
water has a latex concentration of 500 ppm.
[16] Latexes are said to enhance the anti-skid or friction properties of
paper (Miranda, 9:30 to 10:1).
[17] Latexes and compositions comprising latex and silica are known to
improve the printability of paper (id., 2:26-29; 3:4-7).
[18] Miranda's anti-skid composition is said to enhance the printability
properties of paper (id., 15:21 to 16:5).
[19] According to Miranda, the alcohol (i.e., organic additive) in its anti-
skid composition is said to improve stability and to enhance
cleanability of the machinery used to apply the composition (id.,
16:13-21).
