A compound of the chemical formula (I) ##STR1## in a specific crystalline form, processes for its preparation, and its use for pest control.

Crystalline form and its preparation

Herbicides based on an aqueous suspension of from 20 to 50 percent by weight of 1-phenyl-4-amino-5-chloro-pyridaz-6-one or 1-phenyl-4-amino-5-bromo-pyridaz-6-one, from 2 to 10 percent by weight of dispersant, from 0.5 to 5 percent by weight of silica and from 0.5 to 5 percent by weight of a block polymer of propylene glycol, propylene oxide and ethylene oxide, which additionally contain a thiolcarbamate, a chloroacetanilide or a 2,6-dinitroaniline, the weight ratio of pyridazone to thiolcarbamate, chloroacetanilide or 2,6-dinitroaniline being from 4:1 to 1:2, a process for their preparation, and their use for combating undesired plant growth.

Herbicides based on pyridazones

A new valuable fungicide based on N-tridecyl-2,6-dimethylmorpholine as the active ingredient, the said ingredient being in the form of microcapsules of which the wall consists of a polymer while the core contains the active ingredient.

Fungicide

Laminates for the manufacture of flexographic printing plates and containing (a) a layer consisting essentially of a photocrosslinkable mixture of a two-block copolymer of from 30 to 95% w/w of a diene hydrocarbon and from 5 to 70% w/w of a styrene monomer or a partially hydrogenated product thereof with a compatible monomer having at least one C--C double bond, said mixture containing a photo-initiator, (b) a non-photocrosslinkable elastomeric underlayer having a Shore A hardness of from 15 to 70 and (c) a non-photocrosslinkable stablizing layer preferably between layers (a) and (b).

A process for the manufacture of thin layers based on polyurethane elastomers. A liquid reaction mixture essentially consisting of (A) polyesters, polyethers, polyester urethanes or polyether urethanes, all of which contain at least two hydroxyl groups in the molecule, and diisocyanates or (B) prepolymers obtained from the hydroxyl-containing compounds mentioned under (A) above with an excess of diisocyanates, said prepolymers containing at least two isocyanate groups in the molecule, and at least one of the compounds mentioned under (A) above which are capable of reacting with isocyanates, to which reaction mixture a minor quantity of substantially compatible monomers having at least two photocrosslinkable C--C multiple bonds and optionally a photopolymerization initiator have been added, is applied to a substrate to form a coating thereon, which coating is then gelled by irradiation and finally thermocured. The process of the invention is particularly suitable for the continuous manufacture of uniformly thin layers of soft polyurethane elastomer showing narrow tolerance limits.

Manufacture of thin layers of polyurethane elastomers

The invention relates to relief plates for flexographic printing comprising a relatively soft elastomeric base (U) having a modulus of elasticity of from 10 to 200 kg/cm.sup.2 and a thickness of from 0.5 to 6 mm and, firmly bonded thereto, a thin, relatively hard, difficultly soluble intermediate layer Z having a modulus of elasticity of from 1 .times. 10.sup.3 to 2.1 .times. 10.sup.6 kg/cm.sup.2 and a thickness of from 5 to 500 .mu. and, firmly bonded to said intermediate layer Z, a relief layer P' consisting of a photocrosslinked elastomeric mixture having a modulus of elasticity of from 30 to 2000 kg/cm.sup.2 and a thickness of from 200 to 300 .mu., the modulus of elasticity of the photocrosslinked relief layer P' being the same as or higher than that of the base U and the neutral surface of the relief plate lying in or near the intermediate layer Z. The invention also relates to photosensitive laminates for the production of such plates.

Laminates for the manufacture of relief printing plates

Laminates for the production of relief plates for flexographic printing, by imagewise exposure and washing out with a developer solution have, on a base optionally provided with an elastomeric layer, a photo-crosslinkable layer containing a photoinitiator and consisting of a polyurethane elastomer which has been prepared in a special manner from an aliphatic saturated polyesterglycol, an aliphatic diisocyanate, but-1-ene-3,4-diol and, if desired, another diol and which has a Shore A hardness of 30 to 90.degree. in the photo-crosslinked state, the elastomer being optionally mixed with a photo-crosslinked monomer.
