ABSTRACT:
A process for the formation of microcapsules having at least two polymeric substances forming the final microcapsule walls comprising forming a stable emulsion droplet comprising an amphiphilic polymeric agent and the material to be encapsulated and coupling to said amphiphilic polymeric agent at least one polymeric substance to form a substantially impermeable wall about said material, said at least one polymeric substance being capable alone of reacting with said amphiphilic polymeric agent or capable of coupling with said amphiphilic polymeric agent in the presence of a coupling agent capable of reacting with said amphiphilic polymeric agent and said at least one polymeric substance. Also the resultant microcapsules and products, preferably, transfer sheet materials utilizing said microcapsules.
