Abstract
Abstract There is disclosed an anti-dazzling and electrostatic charge-preventive transparent coating material comprising at least two kinds of conductive metallic compounds dissolved in an organic solvent and concentrated, the concentrate being added with water and catalyst to form a transparent solution containing fine particulates, ethyl silicate dissolved in another organic solvent, said transparent solution and the ethyl silicate solution being mixed together to cause hydration and polycondensation, thereby leading the growth of particulate solid ingredient.
