Abstract: A two-component system for developing photosensitive materials provides a developing process which is not highly dependent upon critical values of time and temperature. The resultant developed materials possess less graininess than might be expected with conventional developer systems. The two-composition system is comprised of a first and a second composition employed as aqueous solutions, each containing an alkali sulfite. The first compositon comprises a phenylamine developer compound and hydroquinone.

Abstract: This invention relates to a radiation-sensitive, silver-free recording material for direct optical recording with high sensitivity, characterized by its exceptional resistance to light and heat and large solubility. This is achieved by the fact that the recording material contains as coloring substances, azo dyestuffs of the general formula ##STR1## R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 are the same or different and are halogen, alkoxy, alkyl, acetyl, amino; R.sub.8 hydroxy, alkoxy or acetylamino. The material distinguishes itself by the different processing variations that are possible so that with a same basic type, it is possible to obtain pictures operating according to a positive principle as well as according to a negative principle.

Abstract: The present invention is concerned with enhancement of resist development. In particular it is concerned with obtaining high solubility rate ratio between the exposed and the unexposed regions of a resist and also obtaining shorter development time. These objectives are achieved by treating the resist with a liquid trialkylamine having from two to eight carbon atoms in each alkyl group.
