ABSTRACT:
A process for dispersing particles of an organic commpound in water is disclosed, which comprises dispersing the organic compound in water using (1) a water-soluble high molecular weight compound having a molecular weight of at least 10,000 and (2) a copolymer formed from a monomer represented by the following formula (I) and a monomer represented by the following formula (II), said copolymer having a molecular weight of not more than 10,000: ##STR1## wherein M.sub.1 and M.sub.2 each represents an alkali metal atom or an ammonium group; R.sub.1 represents a hydrogen atom, a methyl group, or an ethyl group; and R.sub.2 represents an alkyl group having from 2 to 18 carbon atoms.
A process of producing a heat-sensitive recording material is also disclosed, which comprises the steps of:
