Abstract
1355124 Microcapsules CIBA-GEIGY AG 4 Nov 1971 [6 May 1971] 51394/71 Addition to 1301052 Heading B8C [Also in Division C5] Solids and liquids are encapsulated by dispersing them in a solution of a reactive surfaceactive agent, e.g. an aminoplast derivative, adding thereto a solution of an aminoplast precondensate of low surface activity and causing a reaction to occur between the aminoplast derivative and precondensate whereby an insoluble product is produced which encapsulates the dispersed material. Suitable surface-active derivatives are urea-formaldehyde and melamine-formaldehyde precondensates which are substituted by both hydrophobic and hydrophilic groups and curable ethers of methylol ureas and methylolmelamines, many examples of which are described. Suitable aminoplast precondensates are dimethylolmelamines, hexamethylolmelamines, unetherified methylolmelmine and methylol ureas and methylolmelamines etherified with alcohols having at most 3 carbon atoms. Examples relate to the encapsulation of petroleum (to give a solid fuel), dibutyl phthalate (to give a lubricant), crystal violet lactone (for use in "carbonless" copying paper), red dye in paraffin oil (for a red copying paper) and an azo pigment.
