ABSTRACT:
The present invention provides a copolymer comprising repeating units derived from (A) at least one fluoroalkyl (meth) acrylate represented by the following general formula (I) or (II):wherein, X1represents —O— or —NR3—; R1represents —H or —CH3; R3represents a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 12 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 12 carbon atoms, a substituted or unsubstituted aryl group having 6 to 12 carbon atoms or a substituted or unsubstituted aralkyl group having 7 to 24 carbon atoms; R2represents H or F; m is an integer ranging from 0 to 10; n is an integer of 2 or 3; and o and p each represents an integer of 1 or 2, and (B) at least one polyoxyalkylene group-containing ethylenically unsaturated monomer, and also provides an image-forming composition, a presensitized plate useful for preparing a lithographic printing plate, a paint composition or a photo resist composition comprising the copolymer. The fluoroaliphatic group-containing copolymer can provide a coating composition capable of simultaneously satisfying the requirements for the ability of a coating liquid to wet the base material and the uniform coating ability upon the application of the liquid and the post-processing aptitudes such as the re-coating ability of the coated film and developing ability as well as the foaming ability of the coating liquid.
