Abstract: Modified aminotriazine-formaldehyde condensation products which are active against microorganisms are prepared by reacting curable condensation products of formaldehyde and an aminotriazine with an aryl-mercury compound of the general formula <FORM:0939614/IV(a)/1> where R is an aryl radical and X is an anion.  The condensation products used may be etheri-fied.  Aminotriazines specified are melamine, melam, melem, ammeline and 2-chloro-4,6-diamino-1,3,5-triazine.  The mercury compound may be phenyl-mercury hydroxide, phenyl-mercury borate, phenyl-mercury nitrate, phenyl-mercury salts of organic acids containing more than four carbon atoms, phenyl-mercury formate, phenyl-mercury acetate, phenyl-mercury lactate, m-tolyl-mercury acetate, p-aminophenyl-mercury acetate, p-aminophenyl-mercury lactate, p-aminophenyl-mercury sulphate, p-dimethylami-nophenyl-mercury lactate, p-diethylaminophenyl-mercury acetate, p-hydroxyphenyl-mercury chlo-ride, p-diethylaminophenyl-mercury chloride and the corresponding bromides or iodides.  The reaction may be performed in solution in water and diethylene glycol, glycerol diacetate and magnesium chloride may be present.  In one example the aminotriazine resin is a mixture of hexamethylolmelamine hexamethyl ether, trimethylolmelamine trimethyl ether and the reaction product of stearic acid methylolamide and hexamethylolmelamine hexamethyl ether.  The products may be dispersed in water by means of, for instance, mono-oleyldiethylethylendi-amine dimethyl sulphate and used for treating textiles or organic materials or the products may be formed in situ in or on such materials.  Specification 742,812 is referred to.ALSO:Cotton fabrics are protected from microorganisms by treatment with the reaction product (see Group IV(a)) of a curable aminotriazine-formaldehyde condensation product and an organomercury compound of formula R-Mg-X, where R is an aryl radical and X is an anion.  The reaction product may be applied in aqueous solution and, if desired, condensed further on the fabric. Alternatively, the reaction product may be formed in situ on the fabric.  Specification 742,812 is referred to.ALSO:Plant seeds, e.g. dwarf bean seeds, are protected from micro-organisms by treatment with the reaction product (see Group IV(a)) of a curable aminotriazine -formaldehyde, e.g. melamine -formaldehyde condensation product and an organo-mercury compound of formula R-Mg-X where R is an aryl radical and X is an onion. Specified organo-mercury compounds are:- phenyl mercury hydroxide, formate, acetate, nitrate, borate and lactate, metatolyl mercury acetate, para-aminophenyl mercury acetate, lactate and sulphate, paradimethylamino-phenyl mercury lactate, paradiethylamino-phenyl mercury lactate, acetate and chloride and para-hydroxyphenyl-mercury chloride.  The reaction product may be condensed further on the seeds.  It may be applied in aqueous solution or suspension which may contain emulsifiers, adhesives and other bactericides, fungicides and insecticides. Specification 742,812 is referred to.ALSO:Plants and animal tissues are protected from micro-organisms by treatment with the reaction product (see Group IV (a)) of a curable aminotriazine - formaldehyde condensation product and an organomercury compound of formula R-Mg-X, where R is an aryl radical and X is an anion.  The reaction product may be condensed further on the organic matter to be protected.  It may be admixed with diluents, e.g. water, emulsifiers, adhesive agents, other bactericides or fungicides and insecticides, when in use. Specification 742,812 is referred to.
