ABSTRACT:
This invention relates to a radiation-sensitive copying composition comprising a compound (1) which splits-off an acid upon irradiation and a compound (2) having at least one group selected from the group consisting of a carboxylic ortho acid ester group and a carboxylic acid amide acetal group, which composition, upon irradiation, forms an exposure product having a higher solubility in a liquid developer than the non-irradiated composition.
