Abstract: A novel fluorinated aromatic acetal polymer comprises at least one unit of A and at least one unit of B or C, or at least one unit of each of A, B and C and optionally further comprises at least one unit of either D or E or at least one unit of each of D and E, wherein the units A and B and/or C, and optionally D and/or E are linked together by single covalent C-C bonds and have the formulae: 1 wherein RA is H or C1-C11 alkyl, or an aryl group that does not contain fluorine, and RB and RC are an aryl groups that contain fluorine. The polymer is prepared by reacting a hydrolyzed polyvinyl acetate polymer or copolymer with at least one non-fluorinated aldehyde component, and at least one fluorinated aromatic component. The polymer is useful is preparing a photosensitive composition which comprises at least one diazo resin and at least one such fluorinated aromatic acetal polymer. Such a photosensitive composition may be applied to a support to form an imageable member which may be imaged to form a lithographic printing plates.p
