Abstract: The present invention describes aqueous dispersions which are substantially free of protective colloids or emulsifiers, containing in a dispersed form a) a polyurethane (A) containing hydrophilic groups, causing water dispersion of said polyurethane which is substantially free of C-C double bonds and b) a prepolymer containing 0.1 to 1 mol radically polymerizable C-C double bonds per 100 gr. of prepolymer.

Abstract: Aqueous dispersions (AD) containing a polyurethane (PU) derived from (a) 4-30C di-isocyanates, (b) diol(s), of which (b1) 10-100 mole% have a mol. wt. of 500-5000 and are derived from (b1.1) (4-30C alkyl and/or alkenyl)-succinic acid, (b1.2) 0-60 mole% (based on b1.1) of another dicarboxylic acid and (b1.3) a diol with a mol. wt. of 60-500, (b2) 0-90 mole% have a mol. wt. of 60-500 and (b3) 0-90 mole% are diol(s) other than (b1.1) with a mol. wt. of 500-5000, (c) monomers other than (a) and (b) with two isocyanate (NCO) groups or two NCO-reactive groups and also one hydrophilic or potentially hydrophilic group to confer water-dispersibility on the PU, (d) optionally multifunctional compounds other than (a)-(c) with reactive alcoholic hydroxyl, primary or secondary amino, or NCO groups, and (e) optionally mono-functional compounds other than (a)-(c) with one reactive group as in (d). Also claimed are articles of leather, paper, textiles, plastics or metal, coated or adhesively bonded with (AD).

Abstract: Producing isocyanurate and uretdione gp.-contg. polyisocyanate mixts. with low colour values (I) comprises catalytic oligomerisation of (cyclo)aliphatic di-isocyanates (II), removal of unreacted monomers and subsequent treatment with radical-forming azo cpds. (III). Also claimed are mixts. with low colour values (I) as obtd. by this process. (III) have decompsn. pt. 20-150 (pref. 50-100) deg. C; the reaction is carried out at above the decompsn. temp., using 200-5000 (pref. 500-3000) ppm (III) (w.rt. mixt. I) and continued until nitrogen evolution ceases. Pref. (II) is 1,6-di-isocyanatohexane (HDI); oligomerisation is carried out at 0-100 deg. C in the presence of catalysts such as tetraalkylammonium cpds., Zn salts of alkylcarboxylic acids etc., after which the catalsyt is deactivated (e.g, by heat) and unreacted (I) is removed by evapn. Various suitable azo cpds. (III) are given; pref. (III) is AIBN. USE/ADVANTAGE - Used for the prodn. of high-grade polyurethane (PU) paints with high light stability and weather resistance. The invention provides a simple method for producing light-coloured (I) without interferring with the oligomerisation reaction, or for further lightening the colour of dark prods. (I). Cpds. (III) are easily handled (contrast peroxides as used in a prior-art process), and the reaction can be monitored by the evolution of nitrogen.

Abstract: Described is an image-recording sheet for thermotransfer printing, the sheet including an image-recording film comprising, for the major part, a polyurethane or polyester resin containing 0.05 to 0.5 moles of ionic groups per mole-equivalent of isocyanate or dicarboxylic acid used.
