Abstract
Abstract A gel composition suitable for use as a carrier for adhesives, dyes, pigments or the like is formed from a Group II metal salt or Group III metal salt of an aliphatic carboxylic acid having from 8 to 36 carbon atoms and a chelating agent for the metal, dispersed or dissolved in a liquid dispersant that can be water, a water-miscible organic solvent or a mixture of water and at least one water-miscible organic solvent. The gel contains from about 80 to 96 percent by weight of the liquid and the mole ratio of the salt to chelating agent employed is between about 0.5 to 1 and 2 to 1. When employed as an adhesive carrier, the gel contains from 5 to 45 weight percent, based upon the total weight of the adhesive composition, of a water soluble or water dispersible film-forming adhesive such as polyvinylpyrrolidone.
