Abstract: The present invention relates to a radiation curable composition comprising at least one (meth)acrylated compound compound (A); and at least one inert polyester (B) that is prepared from a (i) polyol component comprising at least one cyclic ether polyol and (ii) from a polyacid component. The present invention further relates to their preparation and uses.

Abstract: The invention relates to amino(meth)acrylates obtained from the reaction of amines with a mixture of urethane(meth)acrylates and (meth)acrylated diluent sand their use for making coatings, adhesives, varnishes and inks. The amino(meth)acrylates of the invention are particularly suited for use in sealer compositions for parquet and laminate floors.

Abstract: The invention relates to a radiation curable aqueously dispersed polyester resin composition containing an emulsifier D and the reaction product AC of a hydroxy functional polyester resin A and an olefinically unsaturated compound C which can be radically polymerized and which is attached to the polyester resin backbone by an ester linkage or a urethane linkage. The invention also relates to a process for its preparation and to a method of use thereof.

Abstract: The present invention relates to a radiation curable composition comprising at least one ethylenically unsaturated compound (A) and at least one inert OH-terminated polyester (B) prepared from a polyol component that comprises ethylene glycol and from a polycarboxy component that comprises phthalic acid and/or phthalic anhydride. These polyesters can be further modified to bear moieties comprising photo-initiating activity. The present invention further relates to their preparation and their use in for instance lithographic and flexographic applications.

Abstract: The present invention relates radiation curable composition comprising at least one ethylenically unsaturated compound (A); at least one inert polyester resin (B); and at least one inert resin (C) different from (B). These present invention further relates to their preparation and their uses, especially in inks.

Abstract: A method and an apparatus for inactivating contaminants in blood products are disclosed. The blood product is flowed past an emitter of type C ultraviolet radiation while controlling the flow of the blood product so that the irradiation doses which are received by the blood product are lower than 640 joules/m2. The blood product is substantially free of nonenveloped viruses after the irradiation. The apparatus includes an emitter of type C ultraviolet radiation placed so as to emit the type C radiation toward the blood product in a quartz tube or a tube made of polymerized material which does not absorb type C radiation. The apparatus also includes a flow meter for controlling the flow rate of the blood product to be treated.

Abstract: A method and apparatus for inactivating contaminants, particularly nonenveloped viruses, in blood products without the need for quenchers in the blood products. The blood product is flowed through a flow meter at a controlled flow rate and subjected to type C ultraviolet radiation, where the irradiation dose received by the blood product is less than 640 joules/m2. The blood product does not contain quenchers when being irradiated, and the blood product retains more than 85% of its Factor VIII activity after being subjected to the radiation. The produced blood product is free of viruses and quenchers, avoiding potential toxicity due to the quenchers. The apparatus includes a source of UVC light, a quartz tube containing the blood product while it is exposed to the UVC light, a flow meter for controlling the flow rate of the blood product to be treated, and a pump. The UV light preferably emits light at 254 nm.

Abstract: A fibrinogen concentrate has a purity of 98% or higher and is free of viral contaminants and proteases. The fibrinogen concentrate is obtained by subjecting a solubilized plasma fraction containing fibrinogen to a viral inactivation chemical treatment using a solvent/detergent, subjecting the resulting viral-inactivated fraction to precipitation in a solution containing an amino acid at an acidic pH to obtain a supernatant, filtering the supernatant to obtain a purified fibrinogen concentrate, and recovering the purified fibrinogen concentrate.
