Abstract
A filming composition comprises an acryl emulsion having a molecular weight of 1.5.about.2.5 million and a decomposition starting temperature of 200.degree..about.250.degree. C., as a main component. The composition has a tendency to decompose at low temperature and can be completely decomposed and removed during frit sealing, without the need for separate baking or complex equipment. A screen having good characteristics can be obtained through an advantageous method.
