Abstract
In a monolithic ink jet printhead, a structural layer is made comprising cavities, obtained from the polymerization of a solution of a monomer, or an oligomer, and a photointiator; during the polymerization by radiation, acid species are unduly generated in zones protected by a mask, due to reflection of the radiation on reflecting surfaces of the support of the sructural layer; these acid species cause undue polymerization of the solution on the inside of the cavities to oppose the formation of these acid species, a polymerzation inhibitor basic compound is used.
