Abstract
PURPOSE:To form a visible latent image of high contrast and to obtain superior alkali developability by using a photosensitive material contg. specified naphtho- quinone-1,2-diazido-5-sulfonic acid ester so as to show a clear hue change in imagewise exposure. CONSTITUTION:4-Hydroxyphenyl or other ester of o-naphthoquinone-1,2-diazido-5- sulfonic acid represented by the formula (where R is H, halogen, NO2, alkyl or alkoxy, n is 1-3 and when n is >=2, R and R are the same or different) is dissolved in an alcohol or cellosolve solvent together with an alkali-soluble resin such as phenol-formaldehyde resin, and the soln. is applied to a support such as an Al plate and dried to form a photosensitive layer. Thus, a photosensitive material for a lithographic original plate is manufactured. When this material is exposed, said compound shows a clear hue change. The exposed part is easily removed by dissolution in an alkali developer, and high-contrast unexposure color of the compound remains at the unexposed part.
