A process for forming microcapsules having discrete capsule walls comprising the steps of:

Method for producing amine-formaldehyde microcapsules and photosensitive

A process for producing photosensitive microcapsules having an extended dynamic range and the microcapsules produced thereby are disclosed; the process includes:

Process for producing encapsulated photosensitive composition by

A process for preparing microcapsules which comprises dispersing a hydrophobic oily liquid in a continuous aqueous phase, the hydrophobic oily liquid containing a pre-wall former and at least one chain extender, the chain extender being a polyhydric compound which is capable of reacting with the pre-wall former at a rate such that the chain extender does not substantially react with the pre-wall former prior to dispersing the hydrophobic oily liquid in the continuous aqueous phase; and forming capsule walls around the droplets of hydrophobic oily liquid in the continuous aqueous phase.

Method of making microcapsules having an improved pre-wall

The present invention is directed to a method for preparing microcapsules which comprises:
