Abstract:
A dark colored water-based paint composition, which has excellent adhesion to glass, comprising:(i) water-soluble sodium silicate forming 15 to 30 weight percent of said composition,(ii) water forming 20 to 30 weight percent of said composition;(iii) water-soluble base in an amount sufficient to provide said composition with a pH of at least 10.5;(iv) finely divided metal oxide powder selected from the group consisting of oxides of copper, iron, nickel, cobalt and mixtures thereof forming 25 to 50 weight percent of said composition and having a particle size, on average, less than 7 microns;(v) low-melting glass frit powder melting below 1300.degree. F. forming about 25 to 40 weight percent of said composition and having a particle size, on average, less than 10 microns;(vi) particles of soda-lime-silica glass forming 0 to 25 weight percent of the composition and having a diameter, on average, less than 20 microns and having a melting point of at least about 1700.degree. F.; and(vii) zinc oxide forming 0 to 10 weight percent of said composition.
