Abstract: The process produces a sensitized lithographic printing plate from an aluminium base which has been pretreated mechanically, chemically and/or electrochemically in the standard way and anodised, and a photosensitive copying layer applied to said base, a thin hydrophilising layer consisting of a hydrolysate or condensate of at least one silane being applied between said base and copying layer. … These lithographic printing plates are suitable, in particular, for offset printing.

Abstract: Aq. developer soln. (I) contg. basic cpd(s)., with pH over 7, for negative or positive working light-sensitive offset printing plates based on light-sensitive diazo cpds. contains 0.1-50 g/l (silane(s) of the formula X-(CH2)y-Si(R1)n(OR2)3-n (II), where R1 and R2 are 1-9C alkyl or 6-12C aryl; X is ZO-CO-CHR3-, R4O-CO-CHR3-, ZO-CO-CH=C(COOR5)-, R4O-CO-CH=C(COOR5)-, a 2,5-dioxo-2,5-dihydro-fur-3-yl gp., (R6O)2P(=O)-, (Hal)2P(=O)-, ZO3S-, HalO2S-, ZO3S-Ar- or HalO2S-Ar- gp.; R3 is H, 1-9C alkyl or 1-9C acyl; or the acyl gp. R3 + the HO-CO-=CH= gp. form a carboxylic anhydride ring; R4 and R5 are 1-9C alkyl or 6-12C aryl; R6 is H, 1-9C alkyl or 6-12C aryl; Z is H or an alkali metal; Ar is 6-12C arylene; Hal is Cl or Br; y is 1-4 and n is 0-1. (II) is dissolved in (I) in hydrolysed form, esp. in salt form. More specficially, X is (R6O)2P(=O)-; R2 and R6 are H, 1-9C alkyl or 6-12C aryl; y = 2; and n = 0. In particular, (II) is the K (2-(trihydroxysilyl)ethyl)phosphoante (IIA). ADVANTAGE - The addn. of (II), esp. phosphonic acid silanes, maximises the life of (I), without impariing the reproduction quality and ensures that the developed printing plates run freely in the printing machines and give large editions.

Abstract: The invention relates to novel 4-[(meth)acrylamidomethyl]pyrazoles and isoxazoles of the general formula (I) in which R denotes a hydrogen atom or a methyl group; R denotes a hydrogen atom, a methyl group or an ethyl group; R and R denotes an alkyl group having 1 to 6 C atoms or an unsubstituted or substituted aryl group having 6 to 20 C atoms, where R and R can be identical to or different from one another; X denotes an oxygen atom or an NR group in which R stands for a hydrogen atom or a radical having the meaning of R or R . The invention in addition relates to a process for the preparation of the 4-[(meth)acrylamidomethyl]pyrazoles and -isoxazoles of the general formula (I) and the use of these compounds, in particular for polymerisation and preparation of homo- and copolymers.

Abstract: An electrophotographic recording element consisting of an aluminum base, which is mechanically, chemically and/or electrochemically pretreated in a conventional manner, and a photoconductive layer which is applied to this base is produced by a process in which a thin layer which imparts hydrophilic properties and consists of a hydrolysis product or condensate of a silane is applied between the base and the photoconductive layer. These recording elements are particularly useful for electrophotographic offset printing.

Abstract: Prodn. involves coating an Al (alloy) plate with a soln. of a photosensitive, negative working compsn. (I) in diacetone alcohol (II) as solvent; and drying by removing (II). (I), which can be developed with aq. alkaline developer solns., contains a photosensitive diazonium resin (III), a polymeric binder (IV), a colour change system and opt. other additives. The residual (II) content of the coating is adjusted to and kept at 0.1-1.5 (wt.)% during or after drying. ADVANTAGE - The residual (II) ensures max. colour change and high contrast on exposure, which are not affected by humidity or moisture, e.g. from damp fingers during handling.

Abstract: Process for anodising the surface of plates, foils or strips made of aluminium or aluminium alloys in an aqueous electrolyte which contains one or more acids and also, optionally, one or more additives and which contains, as additive or as one of the additives or as acid or as one of the acids, a silane or a plurality of silanes of the general formula I where the indices and the variables have the following meaning: y is an integer from 1 to 4; n is 0, 1 and 2 independently of y; R and R are C1-C9-alkyl and C6-C12-aryl, R and R being identical to, or different from, each other; and X is the radicals X to X , where the variables have the following meaning: R is a hydrogen atom, C1-C9-alkyl, an alkane-carboxylic anhydride ring formed from the alkanecarboxylic acid radical containing 1 to 9 carbons atoms and a carboxylic acid group linked to R3 R and R are the radical R ; R is a hydrogen atom and the radical R ; Z is a hydrogen atom and an alkali metal cation; Ar is C6-C12-arylene; and Hal is a chlorine and bromime atom; the silanes of the general formula I (= silanes I) being dissolved in the electrolyte solution in hydrolysed and/or condensed form. Also the use of the plates, foils or strips made of aluminium or aluminium alloy anodised by this process for producing bases for photosensitive lithographic printing plates or offset printing plates.

Abstract: Methacrylate (co)polymers containing carbazolyl side groups contain or are composed of repeating units of the general formula (I) (I) where m is an integer of from 3 to 11. The novel methacrylate (co)polymers containing carbazolyl side groups can advantageously be used as photoconductors in photoconductive layers, in particular of electrophotographic recording elements.
