摘要：<p>PROCESS FOR MAKING AN IMAGING MEDIUM SOLUTION A special process for making an imaging medium solution suitable for use in the formation of ablative imaging media such as video discs, microlithographic films, and chemical etch resisttype films. A thoroughly-mixed dye dispersion is filtered and added to a thoroughly mixed nitrocellulose solution, to form an imaging medium solution that is, in turn, nitrocellulose heated to a temperature of 50.degree.C for a time duration of at least one hour. After cooling to room temperature, the resultant imaging medium colloidal solution has a highly stabilized viscosity and can be used to form films of precise, uniform thicknesses.</p>
