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 method for preparing microcapsules which comprises:

Method for preparing microcapsules having improved pre-walls, and

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:

Methods for the production of microcapsules using functionalized

Method for polymerizing a monomer suspended in water which comprises: Preparing a polymerization mixture of a water immiscible, liquid, ethylenically unsaturated monomer, a polyisocyanate and an oil soluble free radical initiator, dispersing said mixture in a solution of water and a surfactant, and effecting polymerization of said monomer.

Microsuspension polymerization

A process for producing microcapsules comprising the steps of: adding a hydroxy or amine functionalized acrylic resin or copolymer to an aqueous emulsion including a dispersed internal phase composition;
