Abstract

913,764. Lithographic printing plates. ALGRAPHY Ltd., and ADAMS, R. A. C. Aug. 26, 1959 [Sept. 2, 1958], No. 28197/58. Class 98 (2). [Also in Group IV (a)] Lithographic printing plates may be coated with light sensitive materials prepared (see Group IV (a)) by (i) reacting (a) a linear epoxy resin which is an organic solvent soluble polyalcohol with more than one but not more than two terminal epoxy groups, with (b) an aliphatic alcohol containing two primary alcohol groups and at least one secondary alcohol group per molecule in an amount substantially equivalent to the epoxy content of the resin (one primary alcohol group being equivalent to one epoxy group) such that the hydroxyl equivalency of the alcohol is less than that of di-p-phenylol- 2,2-propane (i.e. less than 114), and (ii) esterifying with cinnamic acid or an esterifiable derivative thereof (e.g. cinnamoyl chloride), the solvent soluble polyether alcohol thus produced which contains no epoxy groups but has a lower hydroxyl equivalency and higher molecular weight than the original epoxy resin. Compounds specified are :-(a) epichlorhydrin/bisphenol A; (b) sorbitol. In Example (1) a solution of such a cinnamic ester and Michler's ketone in cyclohexanone/toluene was whirlcoated on to an aluminium plate; the plate was then exposed, developed in the same fresh solvent, rinsed in toluene, dried, and hand-inked by normal lithographic technique. A second example is similar. Specifications 713,947, 717,708, 717,710, 717,712 and 743,455 are referred to.
