Abstract: PROBLEM TO BE SOLVED: To obtain the subject mixture stable to preservation, mixable and processable, having high reactivity and scarcely yellowing by including a monoacylphosphine oxide and a diacylphosphine oxide. SOLUTION: This mixture is obtained by including (A) a monoacylphosphine oxide which is preferably a liquid at 21 deg.C and represented by formula I [R is a 1-18C alkyl, phenyl or the like; R is phenyl or the like; R is a 1-18C alkyl, a (substituted)phenyl or the like] (e.g. 2,4,6- trimethylbenzoylethoxyphenylphosphine oxide), (B) a diacylphosphine oxide that is preferably a solid at 21 deg.C and represented by formula II (R is a 1-18C alkyl or the like; R and R are each a 1-18C alkyl, phenyl or the like) [e.g. bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide]. The contents of the components based on the sum total of the weights of the components A and B are preferably 70-98 wt.% of the component A and 2-30 wt.% of the component B.

Abstract: PROBLEM TO BE SOLVED: To obtain a coating material radiation-curable on substrates such as metal, leather and wood by mixing a water-dispersible polymer and a water- soluble compound each of which is radiation-curable and having α,β-ethylenic unsaturations with water in a specified ratio. SOLUTION: 5.0-90.0 wt.% water-dispersible polymer being radiation- polymerizable and having at least one α,β-ethylenic unsaturation (e.g. ester of an α,β-ethylenically unsaturated monocarboxylic acid with a hydroxyl- containing polycondensate) is mixed with 0.1-90 wt.% compound (e.g. aliphatic epoxide acrylate) being radiation-polymerizable, having at least one α,β-ethylenic unsaturtion and being water-soluble or capable of being diluted with at least 10 wt.%, based on the total weight of the material, water, at most 20 wt.% arbitrary photoinitiator, at most 60 wt.% filler, at most 20 wt.% additive and water. Thus, a high-solid-content coating material which requires no physical drying after application can be obtained.

Abstract: PROBLEM TO BE SOLVED: To obtain a mixture having a good ability to wet pigments, exhibiting a low yield point even at high viscosity, and being useful as a binder by constructing the mixture from a condensation resin constructed from a urea (derivative) and an acidic-CH aldehyde or ketone and a radiation-curable compound having a plurality of (meth)acryloyl groups. SOLUTION: This mixture is constructed from 10-90 wt. % condensation resin constructed from a urea (derivative) and an acidic-CH aldehyde or ketone and, optionally, HCHO, desirably comprising 50-100 wt.% acidic-CH aldehyde or ketone and 0-50 wt.% HCHO, constructed from an aldehyde or ketone (e.g. i-butylaldehyde) and desirably having a molar ratio of the urea (derivative) to the aldehyde or ketone of 1:4 to 1:10 and 90-10 wt. % radiation-curable compound desirably containing a polyester acrylate or a polyether acrylate having two or more, desirably, 2-20 (meth)acryloyl groups.

Abstract: Radiation-curable urethane prepolymers are made from a mixture in which the isocyanate component contains two different trifunctional isocyanates or one tri- and one di-functional isocyanate, or the unsaturated polyol component contains at least two different unsaturated compounds with reactive hydroxyl groups and possibly other hydroxy compounds. A process for the production of radiation-curable, urethane group-containing prepolymers (PU) comprises reacting an isocyanate component (A) containing trifunctional isocyanate(s) (A1) and optionally difunctional isocyanate(s) (A2) with a polyol component (B) containing unsaturated compound(s) with at least one reactive hydroxyl group (B1) and optionally other OH group-containing compounds (B2), in which either (A) contains two different compounds (A1) or one (A1) and one (A2), or component (B) contains at least two different compounds (B1). Independent claims are also included for the following: (1) radiation-curable urethane prepolymers obtained by this process; (2) radiation-curable preparations containing prepolymers (PU) as above and possibly conventional additives etc.; (3) a process for coating substrates by applying PU or preparations containing PU to the substrate, removing any solvent; and hardening with UV or electron beam radiation; (4) coated substrates obtained by this process.
