| titleOfInvention | Radiation-curable water-thinnable urethane resins, their preparation process and their use |
| abstract | Radiation hardenable, water dilutable urethane resins (I) are prepared by mixing (A) 1.0 mole of a cycloaliphatic and/or aromatic diisocyanate with (B1) 0.2-0.6 moles (w.r.t. reactive hydroxyl groups ) of a (meth)acryloyl group containing dihydroxy compound and (B2) 0.4-0.8 moles (w.r.t. reactive hydroxyl groups) of a (meth)acryloyl group containing, initially three or four valent polyol with a residual average hydroxy functionality of 1.0-1.4, such that the sum of reactive hydroxy groups in (B1) and (B2) is equal to 1.0 mole. Up to 50 mol.% of NCO groups of the product of (A), (B1) and (B2) are converted to urethane groups and the resulting intermediate product is mixed with (C) 0.3-0.5 mol. 2,2-bis-(hydroxymethyl)-propionic acid until complete reaction of the hydroxy groups of (C) occurs and optionally with 0.2-0.5 moles of (B2) until complete reaction of the residual free isocyanate groups. The ratio of isocyanate to hydroxy groups in (A) and (C) is 0.9:1 - 1:1 and the carboxyl group content of the product corresponds to an acid number of 20-40 mg KOH/g, that is neutralised to at least 40% by addition of an alkali hydroxide or tert. amine. The double bond equivalent is a maximum of 3.5 mmole/g solid urethane resin. |
