Abstract
A light-sensitive composition comprises at least one water-insoluble and aqueous alkaline-soluble polyurethane resin having N-sulfonylamido, N-sulfonylureido or N-aminosulfonylamido groups. The light-sensitive composition is excellent in developing properties in an aqueous alkaline developer and coating properties. In addition, the images obtained from the composition are good in wear resistance and exhibit high adhesion to the substrate. Thus, the composition is very suitable for use in making IC circuits, photomasks and PS plates which provide lithographic printing plates exhibiting high printing durability.
Claims10
A light-sensitive composition comprising, in admixture, (i) a light-sensitive positive working o-quinone diazide compound in an amount of from 10 to 50% by weight or a light-sensitive negative working diazonium compound in an amount of from 1 to 50% by weight, based on the total weight of the composition and (ii) an aqueous alkaline-soluble polyurethane resin having a N-sulfonyl-amido groups in an amount of from 5 to 90% by weight based on the total weight of the composition, the polyurethane resin having a structure, as basic skeleton, derived from a reaction product of diisocyanate compound represented by the following formula (I) with a diol compound represented by the following formula (II), (III), (IV) or (V):
- ##STR34## wherein R.sub.1 represents a bivalent aliphatic or aromatic hydrocarbon group which may have substituents selected from the group consisting of alkyl, aralkyl, aryl, and alkoxy groups and halogen atoms, with the proviso that R.sub.1 may have other functional groups which are not reactive with the isocyanate groups;
- R.sub.2 represents a hydrogen atom or an alkyl, aralkyl, aryl, alkoxy or aryloxy group which may have substituents selected from the group consisting of cyano, nitro, halogen atoms, --CONH.sub.7, --COOR.sub.7, --NHCONHR.sub.7, --NHCOOR.sub.7, --NHCOR.sub.7, --OCONHR.sub.7, and --CONHR.sub.7, wherein R.sub.7 represents an alkyl group having 1 to 15 carbon atoms;
- R.sub.3, R.sub.4, and R.sub.5, may be the same or different and each represents a single bond or bivalent aliphatic or aromatic hydrocarbon group which may have substituents selected from the group consisting of alkyl groups, aralkyl groups, aryl groups, alkoxy groups and halogen atoms, provided that R.sub.3 to R.sub.5 may optionally have other functional groups which do not react with the isocyanate groups and that two or three of R.sub.2 to R.sub.5 may optionally have other functional groups which do not react with the isocyanate groups and that two or three of R.sub.2 to R.sub.5 may form a ring together with the carbon atoms to which these are bonded;
- R.sub.6 represents a monovalent aliphatic or aromatic hydrocarbon group which may have substituents selected from the group consisting of alkyl groups, alkoxy groups and halogen atoms;
- Ar represents a trivalent aromatic hydrocarbon group optionally having substituents, and Y denotes N-sulfonylamido group.
