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: 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: The prodn. of radiation-curable acrylates (I) comprises (1) reacting hydroxy cpds. (II) with (meth)acrylic acid and (2) reacting the prods. with epoxide(s) (III); cpds. with one or more prim. or sec. amino gps. (IV) are added in or before stage (2), which is then continued until the acid no. of the mixt. has decreased by at least 3 mg KOH/g from its value at the time of addn. of (IV). Also claimed are acrylates (I) obtd. by this process.
