Heat Treatable Painted Glass Substrate, and/or Method of Making the Same
Certain example embodiments of this invention relate to heat treatable painted glass substrates that have less than 11 wt. % (more preferably 5.40 wt. %, and still more preferably 5-9 wt. %) organic content in an as-deposited state, and/or methods of making the same. The paint preferably is curable at a temperature less than 300 degrees C. over a relatively short amount of time (e.g., less than 10-15 minutes), and the cured coated article may be stored for lengthy periods of time before being further processed. In certain example embodiments, the coated article undergoes a significant color change upon heat treatment
