Abstract: The invention relates to a process for producing carbamoyloxy (meth)acrylates which comprises transesterification of hydroxyalkyl carbamates with an (meth)acrylate of formula CH2?CR29—COOR30 wherein R29 is hydrogen or methyl and R30 represents an alkyl group comprising from 1 to 8 carbon atoms, in the presence of an organotitanate, an organozirconate catalyst or an organotin catalyst, the carbamoyloxy (meth)acrylates thereby obtained and their use in radiation curable compositions.

Abstract: The present invention is directed towards water-thinnable phosphorous-containing polymers precursors, their preparation and use. The precursors of the invention are useful in compositions for preparing coatings which impart and/or exhibit resistance to attack, for example which are useful as flame-retardant coatings.

Abstract: The invention relates to a process for the preparation of compound(s) comprising at least one acrylate or methacrylate group, at least one linear carbonate group and at least one 5-membered cyclic carbonate group. The process comprises (A) a selective ring-opening step and (B) a (meth)acrylation step. The process is environment-friendly and compounds obtained are usable in radiation curable compositions, for example in radiation-curable inks.

Abstract: The present invention relates to radiation-curable compositions useful as ink vehicles or inks, in particular UV-curable inks, such as UV-litho inks, comprising a (meth)acrylated styrene allyl alcohol copolymer obtained from the (meth)acrylation of a styrene allyl alcohol (SAA) copolymer with (meth)acrylic acid and/or one or more alkyl(meth)acrylates, and at least one alkoxylated acrylated monomer.

Abstract: There are disclosed star shaped thermoplastic elastomers made of acrylic block copolymers obtained by transition metal catalysed radical polymerisation. The elastomers comprise core arms obtained from monomers or mixture of monomers, whose Tg is from about ?65° C. to about ?20° C., and of shell arms obtained from monomers or mixture of monomers, whose Tg is from about 70° C. to about 160° C. The core copolymer has a polydispersity of 2 or higher and the final copolymer has a polydispersity of from 3 to 10.

Abstract: A radiation curable powder coating composition is disclosed, which comprises a blend of (meth)acryloyl group containing polyphenoxy resin, a (meth)acryloyl group containing resin other than the polyphenoxy resin and other than a (meth)acryloyl group containing amorphous polyester and, eventually, a (meth)acryloyl group containing monomer or oligomer. These powders give coatings with improved chemical resistance and flexibility.

Abstract: The present invention is directed towards phosphorous containing organic materials, processes for making them and uses thereof. These materials preferably impart and/or exhibit resistance to attack, for example they may be useful as flame retardant additives and/or materials. The materials are especially radiation-curable polyester polymers. The phosphorous component used has at least one P—C bond resistant to hydrolysis or transesterification. It can be bis(hydroxymethyl)isobutylphosphineoxide, bis(hydroxypropyl)isobutylphosphine oxide and trishydroxymethylphosphine oxide. In other embodiments, it is 9,10-dihydro-9-oxa-10-phosphaphenantrene-10-oxide.

Abstract: Functionalized pigment compositions produced by reacting a radiation reactive organ metallic coupling agent with a pigment/dye.

Abstract: The present invention relates to powdered thermosetting compositions including a binder which comprises a carboxyl group containing amorphous isophthalic acid containing polyester, a carboxyl group containing semi-crystalline polyester, at least 10 parts by weight, based on the total weight of the binder, of a specific glycidyl group containing acrylic copolymer and a curing agent having functional groups reactive with the polyesters' carboxyl groups. The powdered thermosetting compositions are useful for the preparation of powdered paints and varnishes which give low gloss coatings having an outstanding flow, a remarkable weatherability and excellent mechanical properties.
