A method for forming microcapsules by enwrapping an oily core material in a formaldehyde condensation product formed in situ wherein a dispersant is used of the formula (I): ##STR1## where: M is an alkali metal cation or a quaternary ammonium group,

Sulfonated-ethylene oxide dispersants for use in preparing

A light-sensitive photohardenable composition comprising a reducing agent, a light-sensitive silver halide, a polymerizable compound, and a coumarin or a ketocoumarin.

Light-sensitive polymerizable compositions containing silver compounds

Processes for forming metal patterns such as electric circuits and photosensitive materials useful therein are disclosed wherein a layer of photosensitive microcapsules is used to form a pattern of an adhesive, a metallic pigment, a metal salt or a reducing agent by exposing the layer of microcapsules to actinic radiation and transferring the internal phase to a support member. A pattern of the pigment salt or reducing agent is thereby formed on the support member which is treated with an electroless plating solution to form the metal pattern.
