ABSTRACT:
A process for the preparation of light-sensitive microcapsules comprises encapsuling silver halide and a polymerizable compound with a shell comprising an aminoaldehyde resin in an aqueous medium in the presence of an anionic protective colloid, wherein the anionic protective colloid is a mixture of pectin and a polymer comprising a repeating unit derived from styrenesulfonic acid such as poly(styrenesulfonic acid) and a copolymer of an ethylenic unsaturated compound and styrenesulfonic acid.
