<p>Solid anti-fogging agents such as 5-nitroindazole which are otherwise poorly soluble in water are converted ro readily water soluble compositions that are solids at room temperature when they are first dissolved in water soluble polymers or other organic compounds that have a melting point above room temperature and do not chemically react with the anti-fogging agent. The anti-foggants are preferably dissolved in the polymer or organic compound at or near the compounds' melting point below 175 °C. The solid compositions so formed to contain the anti-fogging agent are combined in predetermined amounts with other solid components of rapid access developers in a solid, single part package to form a single part, rapid access developer having high contrast.</p> |
