Conjugated enals or their methyl acetals react with benzeneselenenyl chloride in the presence of an oxygen nucleophile to give Michael-type adducts. The latter are oxidized into 2-alkylidene 3-oxy propanals and propionic acids.
A conductive sheet supports an interlayer and a photoconductive photoreceptive layer in that order, with the interlayer containing at least one colloidal substance selected from colloidal silica and colloidal alumina, and an organic solvent soluble resin which is composed of
(A) a polymer having an acid value of from 10 to 100 and containing repeating units represented by formula (I) and (II)
wherein R1 represents H or CH3; R2 represents H, -CH3, - C2H5, or a chloromethyl group; and n represents an integer of 1 to 10;
wherein R3 represents H or-CH3; and
(B) at least one polymer selected from a homopolymer and a plural copolymer having a glass transition point (Tg) offrom -70 to 20 °C. It can be utilized as a lithographic printing material having long press life.
An anthraquinone dye represented by the Formula (1), (2) or (3), and an ink jet recording liquid containing a compound represented by the following Formula (1), (2) or (3):
A positive photosensitive composition comprises a compound capable of generating a specified sulfonic acid upon irradiation with one of an actinic ray and radiation and (B) a resin capable of decomposing under the action of an acid to increase the solubility in an alkali developer.
