Claims
- 1. A radiation-sensitive composition which comprises:
- (a) from about 30 to 90% by weight of a polymeric binder which is insoluble in water and soluble in aqueous-alkaline solutions;
- (b) from about 0.1 to 10% by weight of a compound which forms a strong acid under the action of actinic radiation; and
- (c) from about 5 to 70% by weight of a compound containing at least one acid-cleavable C--O--C bond and having a solubility in a liquid developer which is increased by the action of acid, said polymeric binder comprising a copolymer comprised of (i) 40 to 90 mol-% of alkenyl phenol units represented by the formula ##STR3## wherein R denotes a hydrogen atom, a cyanide group, and alkyl group or a phenyl group,
- R.sup.1 denotes a hydrogen atom, a halogen atom, a cyanide group or an alkyl group,
- R.sup.2, R.sup.3 and R.sup.4 each separately denotes a hydrogen atom, a halogen atom, an alkyl group or an alkoxy group, and
- X stands for an integer from 1 to 3,
- and (ii) from 10 to 60 mol-% of units of alkyl acrylate or alkyl methacrylate.
- 2. A radiation-sensitive composition as claimed in claim 1, wherein said vinyl monomer is represented by the formula ##STR4## wherein R.sup.5 denotes a hydrogen atom, a halogen atom or an alkyl group,
- R.sup.6 denotes an alkyl group, an alkoxy group, an alkyloxycarbonyl group, an acyl group, an acyloxy group, an aryl group, a formyl group, a cyanide group, a carboxyl group, a hydroxyl group or an aminocarbonyl group, and
- R.sup.7 denotes a hydrogen atom or a carboxyl group.
- 3. A radiation-sensitive composition as claimed in claim 1, wherein x is 1.
- 4. A radiation-sensitive composition as claimed in claim 1, wherein said compound (c) is a compound comprising at least one from the group consisting of an orthocarboxylic acid ester group, a carboxylic acid amide acetal group, an acetal group, an enolether group and an acyliminocarbonate group.
- 5. A radiation-sensitive composition as claimed in claim 1, wherein R.sup.1 denotes an alkyl group comprising 1 to 4 carbon atoms.
- 6. A radiation-sensitive composition as claimed in claim 1, wherein at least one of R.sup.2, R.sup.3 and R.sup.4 denotes hydrogen.
- 7. A radiation-sensitive composition as claimed in claim 1, wherein at least one of R.sup.2, R.sup.3 and R.sup.4 denotes an alkyl or alkoxy group comprising 1 to 6 carbon atoms.
- 8. A radiation-sensitive composition which comprises a support and a recording layer applied to said support, said recording layer comprising:
- (a) from about 30 to 90% by weight of a polymeric binder which is insoluble in water and soluble in aqueous-alkaline solutions;
- (b) from about 0.1 to 10% by weight of a compound which forms a strong acid under the action of actinic radiation; and
- (c) from about 5 to 70% by weight of a compound containing at least one acid-cleavable C--O--C bond and having a solubility in a liquid developer which is increased by the action of acid, said polymeric binder comprising a copolymer comprised of (i) 40 to 90 mol-% of alkenyl phenol units represented by the formula ##STR5## wherein R denotes a hydrogen atom, a cyanide group, an alkyl group or a phenyl group,
- R.sup.1 denotes a hydrogen atom, a halogen atom, a cyanide group or an alkyl group,
- R.sup.2, R.sup.3 and R.sup.4 each separately denote a hydrogen atom, a halogen atom, an alkyl group or an alkoxy group, and
- X stands for an integer from 1 to 3,
- and (ii) from 10 to 60 mol-% of units of alkyl acrylate or alkyl methacrylate.
- 9. A radiation-sensitive recording material as claimed in claim 8, wherein said support comprises a flexible, transparent plastic film and wherein said recording layer has a free surface covered by a covering film, said recording layer having a lower adhesion to said covering film than to said support.
