Abstract
Vesicular recording materials incorporate a sensitized layer comprising, as vehicle for the sensitizing agent, a quaternized polyelectrolyte, e.g. preferably polymers of dimethylamino ethyl methacrylate. The water sensitivity of the preferred polymers is reduced by copolymerisation with insolubilizing comonomers such as itaconic acid.
