Abstract: 1,209,232. Photo-crosslinkable materials. BADISCHE ANILIN - & SODA FABRIK A.G. March 7, 1968 [March 10, 1967], No. 11073/68. Heading G2C. [Also in Division C3] Photo-crosslinkable compositions for use in the production of relief-bearing plates, sheets or films comprise (a) a highly polymerised substance, (b) at least one monomer having at least two photo-polymerisable double bonds or a mixture thereof with at least one monomer having only one photopolymerisable double bond, (c) 0À01-10% by weight of the total composition of a photo-initiator, and (d) as a polymerisation inhibitor, a N-nitroso hydroxylamine derivative of the formula where R is a monovalent aliphatic, cycloaliphatic, araliphatic or aromatic radical having up to 18 carbon atoms, X is H, a metal atom, or an unsubstituted or substituted ammonium radical, and n denotes a number equivalent to the valency of X. The relief-bearing image is produced by exposing a layer of the composition to light imagewise and then washing with a suitable solvent to remove the unexposed areas. Component (a) may be a polyamide or a cellulose derivative, e.g. cellulose acetate, and the initiator (c) may be diacetyl, benzil, benzoin, benzoin methyl ether, α-methylbenzoin or phenanthraquinone. The monomer with at least two double bonds may be a di- or poly-(meth)acrylate of a polyhydric alcohol or phenol, a bis- or poly(meth) acrylamide derivative of a di- or poly-amine or other compound containing two or more -NH- groups. The reliefbearing articles can be used as printing plates and for the production of fluid control devices. In examples, the photo-crosslinkable layers are adhered to an aluminium support.

Printing plates are produced by imagewise exposing a material containing 40-99% by weight of a polyamide and 60-1% of a compound containing at least one photo-polymerizable double bond and at least one hydrogen capable of reacting with an isocyanate, treating the exposed material with a polyisocyanate and then removing the unexposed areas. Specified compounds are acrylamides and methacrylamides, partial esters of glycols with acrylic or methacrylic acid and hydroxy- or aminostyrenes. The polyisocyanate may be hexamethylene-, p-phenylene, 2, 5 or 2, 6-toluene -, or 1 5-naphthalene-di-isocyanate, 4, 4', 4" triphenylmethane tri-isocyanate or tri-methylolpropane/2, 4-toluene di-isocyanate addition product. The material may also contain a thermal polymerization inhibitor and photo-initiator.

Abstract: 1,154,872. Photo-polymerizable materials. BADISHE ANILIN & SODA-FABRIK A. G. Sept. 7, 1966 [Sept. 8, 1965], No. 39967/66. Heading G2C. [Also in Division C3] Printing reliefs are prepared by exposing a plate, film or sheet of a photo-polymerizable composition to the action of actinic light, through a negative or positive image-bearing transparency, and removing in the desired depth the non-polymerized (non exposed) areas by means of a suitable solvent, said photo-polymerizable composition comprising a mixture of 50 - 90% by weight of a soluble linear synthetic polyamide containing as an integral part of the polymer chain recurring amido groups and 10 - 50% by weight of at least one addition polymerizable monomer containing at least two non-conjugated ethylenic double bonds or a mixture of such monomer with a monomer containing only one ethylenic double bond (said monomer or monomers being compatible to the extent of at least 30% by weight of the polyamidemonomer mixture with said polyamide), and 0À05 - 8% by weight of the polyamide/monomer mixture of at least one compatible carboxylic anhydride dispersed in the polyamide - monomer mixture. The compositions may also contain 0À01 - 10% by weight of the polyamide/monomer mixture of a photo-polymerisation initiator. The plate, film or sheet may be attached to a support, e.g. of metal, wood, paper or plastics material. The polyamide is preferably a copolymer of a lactam and/or nylon salt. Suitable poly-unsaturated monomers include alkylene - bis (meth) acrylamides, poly (meth) acrylyl derivatives of polyamines, (meth) acrylate esters of polyhydric alcohols, urethane and urea compounds obtained by reacting a diol mono (meth) acrylate or a mono - (meth) acrylamide with a diisocyanate, and heterocyclic compounds such as 1, 35 - triacryloyl - hexahydrotriazine- 1, 3, 5 and triallyl cyanurate. Suitable monoethylenic monomers include amides of (meth) acrylic, maleic and itaconic acid, styrene, mono- (meth) acrylate esters, N-vinyl-carbazole, N-vinyl pyrrolidone, N-vinyl-imides, vinyl acetate or propionate, dimethyl maleate and N - vinyl caprolactam. The anhydride component may be an aliphatic, cycloaliphatic or aromatic anhydride; polymeric anhydrides may also be used. Initiators which may be used include vicinal dicarbonyl compounds, α-carbonylalcohols, acyloin ethers, azonitriles, and polynuclear quinones. A thermal polymerization inhibitor, e.g. hydroquinone, p-methoxyphenol or di-t-butyl-p-cresol, may also be present. The photo-polymerization process is suitable for relief printing, indirect relief printing, dry offset printing and autotype intaglio printing.
