    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: The invention relates to storage-stable solutions of film-forming copolymers containing carboxyl groups, whose carboxyl groups are reacted to 5 to 80 % with glycidyl (meth)acrylate, in an inert organic solvent or solvent mixture, these solutions additionally containing a phosphoric acid ester of a hydroxyalkyl (meth)acrylate and optionally o-phosphoric acid, and to a procedure for the manufacture of photosensitive coatings which contain photoinitiators, free-radical-polymerisable ethylenically unsaturated organic monomeric compounds, and if appropriate plasticisers, dyes, colour formers and inhibitors of thermal polymerisation, the manufacture of these coatings taking place in a storage-stable solution of this type. They are particularly suitable for the manufacture of offset printing plates.

    Abstract: The invention relates to novel polyethyleneimine and polyvinylamine derivatives, the polyethyleneimines containing the structural elements Ia and/or Ib and the polyvinylamines containing the structural elements IIa, IIb and IIc in which the following applies to the degrees of polymerisation n, m and p: n >/= 1, m >/= 0 and P >/= 0, and X is CR R PO3R R or CR R SO3R , X , independently of X , is a hydrogen atom, CR R PO3R R or CR R SO3R , Y and Y , independently of one another, are at least one CHR PO3R R or CHR SO3R group and possibly a hydrogen atom, Y and Y , independently of one another and of Y and Y , are hydrogen atoms, CHR PO3R R or CHR SO3R groups, and Z -Z are identical or different inorganic and/or organic radicals, where R and R , independently of one another, are a hydrogen atom, a C1-C12-alkyl group or an aryl group, and R and R , independently of one another, are a hydrogen atom or an alkali metal atom or NR R R R where R to R are identical or different radicals selected from the group consisting of hydrogen, alkyl, aryl, hydroxyalkyl and benzyl. The invention also relates to aluminium-based substrate materials coated with these polyethylenimines and/or polyvinylamines, and to the use thereof for the production of offset printing plates.

    Abstract: A photochromic system contains an oxidizable leuco dye and a photochemically activated initiator which converts the leuco dye to the dye, the initiator being a phenanthroimidazole derivative. The photochromic system is useful for the production of photochromic layers for photoresists and printing plates.
