Fig. 2. Curves 1, 2, and 3 show the spectral radiance factor for equivalent coatings of separate toluenesulfonamide—melamine—formaldehyde Day-Glo pigments containing 0.5% of a dye, either Alberta Yellow, Rhodamine F5G, or Rhodamine B Extra. Curve 4 is for a bright nonfluorescent red-orange printing ink. The illuminant was Source C. A magnesium oxide-coated block was used as a comparison white.

Magnesium acetate also has uses as a dye fixative in textile printing, as a deodorant, disinfectant, an antiseptic in medicine, and as a reagent chemical (see Disinfectants AND ANTISEPTICS Textiles) (6). In the United States, Hoescht-Celanese and Tennessee Eastman are the principal producers of magnesium acetate. These companies make about 36,000 t/yr, which is largely used in-house for the production of cellulose acetate.

Very unstable modifications, like the reddish, chlorine-free a-copper phthalocyanine, can be stabilized with amides or salts of copper phthalocyanine sulfonic acids (59—63). Mixture with other metal phthalocyanines, eg, tin, vanadium, aluminum, or magnesium, also inhibits crystallization change and poor performance in binders and prints (flocculation) due to the hydrophobic character of unsubstituted phthalocyanines.

P.R.48 5, a magnesium salt, was a comparatively recent product but its manufacture has already been discontinued. It is considerably yellower and at the same time more brilliant than P.R.48 4. The pigment is also much weaker in white reductions. Compared to the manganese version, P.R.48 5 does not perform as well if exposed to light and/or weather, and it darkens in full shades. Its primary field of application is the pigmentation of polyolefins, but it is also employed to color PVC and polystyrene. Its application properties and fastness properties in print and in paints largely parallel those of P.R.48 2.

Magnesium acetate is used in the manufacture of rayon fiber for cigarette filters and as a fixative for dyes in textile printing. It also is used as an antiseptic and disinfectant.

This same plant also used the cationic components of the brine, which included alkali metals such as calcium and magnesium, to produce other useful products. Among these products was magnesium oxide, which was used as a nutritional supplement for dairy cows. This material had the trade name of NutriMaster and was also a white powder. Sometime in May 1973, there was apparently a shortage of the color-coded, printed paper bags in which these... 

The main advantages of the photo-polymer system include safer operations that do not use hot metals, such as zinc or magnesium, or plating solutions for the deposition of copper. Processing involves the use of developers such as water, dilute sodium hydroxide, and dilute solutions of sodium carbonate. Because each plate is a copy of the original (not a duplicate from a mould that has been used many times) the print quality is consistent and more predictable. While some of the pressures for change were environmental a bonus is that the overall costs of producing photo-polymer plates are lower than those for the traditional metal plates. 

CATALYST TM is a magnesium salt based catalyst for textile finishing which has been modified to provide stronger catalytic action than that provided by unmodified magnesium chloride catalysts. In addition it will not cause prints to flush when printing is done on fabrics which have been finished and not washed. 

Activated catalyst for use on goods to be over-printed or with water repellent finishes for fast curing—modified magnesium chloride solution.
