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.
Claims16
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 and exposure product having a higher solubility in a liquid developer than the non-irradiated composition.
In the process for recording high-energy radiation which comprises
- (a) imagewise irradiating a radiation-sensitive recording material composed of a support and a radiation-sensitive layer in such doses that the solubility of the layer, especially in water and aqueous solution, increases in the irradiated areas, and
- (b) removing the irradiated areas with a liquid developer,
- the improvement wherein said layer comprises a compound (1) which splits-off acid during irradiation, and a compound (2) which contains at least one group selected from the group consisting of a carboxylic ortho acid ester group and a carboxylic acid amide acetal group.
