Filed: 1971-05-25
Abstract: 1301052 Microcapsules CIBA GEIGY AG 25 May 1971 [26 May 1970] 17054/71 Heading B8C Solid orliquid particles are microencapsulated by dispersing them in a liquid medium (e.g. water) containing a reactive, surface-active "tenside" which is caused to react to form an insoluble compound which coats the particles. Thereafter, the resulting suspension is mixed with a solution of non-surface-active aminoplast precondensates which are again converted to an insoluble form by condensation polymerization and which coats the particles again to give a product with strengthened walls. The term "tenside" refers to soluble surface active compounds having both hydrophobic and hydrophilic groups, in particular aminoplasts of the urea-formaldehyde and melamineformaldehyde types. The aminoplast precondensate used subsequently may be of the same general type but with low surface activity. Examples refer chiefly to the microencapsulation of dyestuffs and adhesives.

Title: Metallisable azo dyestuffs containing sulphonimide groups and metal complex compounds thereof
Inventor: DEHNERT JOHANNES
IPC: C09B43/40
Filed: 1958-05-29
Abstract: The invention comprises metallisable azo dyestuffs containing in ortho- and ortho1- position to the azo bridge a hydroxy, amino or a carboxylic acid group and which are free from sulphone and sulphonamide radicals that are substituted by a halogenalkyl group or a group of the formula -R-X in which R is an aliphatic radical and X is a labile sulphurcontaining substituent (i.e. substituents such as sulphuric or sulphonic acid ester groups which are easily split off in an alkaline medium) and metal complexes thereof, said dyestuffs containing either in the diazo or azo component or in both, at least once a group of formula -SO2-NH-SO2-R (and where the coupling component is a 1-phenyl-3-methyl-5-pyrazolone the disulphomide radical is in the diazo component only) wherein R is a hydrocarbon radical which may or may not be substituted but is different from the azo dyestuff to which the sulphonimide group is attached.  The dyes and the metal complexes are prepared in known manner by diazotisation and coupling of suitable components and the dyestuffs are metallised alone or in admixture with each other or with other metallisable azo or azomethine dyestuffs and if the complexes contain less than two dyestuff molecules per metal atom being reacted, if desired, with colourless complex-forming compounds or metallisable dyes.  Specified metallising agents are salts of chromium, cobalt, nickel and copper. In the preparation of the metal complexes, dyes may be used wherein an alkoxy group or a hydrogen atom rather than a hydroxy group is ortho to the azo group and in these cases dealkylating, metallisation or oxidative coppering processes are employed and such complexes may be demetallised.  The dyes give red, violet and brown shades on nitrogenous materials such as wool and may be used to colour varnishes and cellulose and in spin-dyeing of cellulose acetate. In an example the dyestuff 1-amino-2-phenol-5-sulphonic acid-(41-chloro)-benzenesulphonic acid imide->2-naphthol is heated under reflux in a solution of chromic oxide in formic acid and the chromium complex precipitated as its cyclohexylamine salt. Many further examples are given.  Specifications 637,404, 660,447, 692,073, 754,660 and 766,554 are referred to.
