Abstract
A panel is composed of synthetic resins and coated with an antifogging layer, the panel having a plastics substrate formed as a board or film or molded into any desired shape. The panel further has a heat generating pattern as the antifogging layer formed on the substrate and composed of a conductive paste, and a hard coat covering the layer and mainly composed of a silicone resin. The conductive paste is composed of a resinous binder, a conductive agent and a solvent, and the binder is selected from a group consisting of (i) a saturated polyester, (ii) a mixture of the polyester and a polyvinyl chloride, (iii) a mixture of the polyester and a copolymer of vinyl chloride and vinyl acetate, and (iv) a mixture of the polyester, the polyvinyl chloride and the copolymer. The heat generating pattern layer protects the resin panel from fogging, and the hard coat enhances scratch resistance and weather resistance to the panel.
