The present invention relates to coating compositions, which are curable by radiation and contain

Coating compositions curable by radiation and their use for preparing

A radically curable coating composition containing) 50 to 95 parts by weight of an unsaturated polyester component having a viscosity at 23.degree. C. of 1,000 to 15,000 mPa.s, B) 5 to 50 parts by weight of compounds containing (meth)acryloyl groups and/or vinyl ether groups, C) 0.01 to 0.3 wt. %, based on the total weight, of waxes and/or paraffins having a melting point of 35+ to 100.degree. C. and D) 0 to 10 wt. %, based on the total weight, of at least one plasticizer or carbamic acid resin, and the use of the coating composition for coating substrates, in particular wood substrates.

Radically curable coating compositions and their use for coating wood

The present invention relates to a process for the production of olefinically unsaturated polyester resins containing at least 0.025 moles of urethane groups per 100 g of resin by reacting

Unsaturated urethanized polyester resins, a process for their production

Unsaturated polyester resins having an acid number of from 0 to 50 and a hydroxyl number of from 10 to 150 which are composed of 0.6 to 0.8 moles of groups derived from maleic and/or fumaric acid, 0.2 to 0.4 moles of groups derived from norbornene dicarboxylic acid, 0.6 to 0.8 moles of groups derived from ethylene and/or propylene glycol, 0.2 to 0.4 moles of groups derived from diethylene glycol, 0.1 to 0.2 moles of groups derived from benzylalcohol and/or benzoic acid and 0 to 0.2 moles of groups derived from other alcohols, a process for their manufacture by a solvent-free or azeotropic esterification of said monomers and compositions which can be cured under influence of UV radiation, containing from 40 to 80 parts by weight of said polyester resins, from 20 to 60 parts by weight of styrene from 0.5 to 5 parts by weight of at least one photoinitiator and optionally known auxiliary agents and additives.

Unsaturated polyester resins, a process for their preparation and

Opaquely pigmented coatings can be produced from lacquers based on monomer-free air-drying polyesters by means of UV radiation if hydroperoxides are additionally employed alongside UV initiators.

Process for the production of UV-hardened opaquely pigmented coatings

Unsaturated polyesters of defined composition with a low content of polyalkylene glycol radicals in a narrow molecular weight range can be dispersed in water without external emulsifiers. These dispersions produce, after hardening, water and chemical resistant coatings with good mechanical properties.

Unsaturated polyesters

The invention relates to acryloyl-containing polyesters having acid numbers AN of 1-50 mg of KOH/g of substance and having been polymerized from cocondensed units of
