摘要： A light-sensitive coating liquid, comprising, as an organic solvent, at least one substance represented by the formulae (I) to (III) shown below: ##STR1## wherein R.sub.1 represents an alkyl group having 1 to 4 carbon atoms, R.sub.2 to R.sub.7 each represent hydrogen atom or an alkyl group having 1 to 3 carbon atoms, with the proviso that at least one of R.sub.2 to R.sub.7 is an alkyl group. The light-sensitive coating liquid of this invention is improved in odor, low in toxicity and yet excellent in storability, and is also suitable for preparation of a light-sensitive lithographic printing plate improved in press life and dye remaining.
